Get BonusWhat is RTP in slots and why is this indicator important
Any experienced player knows: RTP (Return to Player) is not just a set of letters, but a vital indicator for anyone who wants to play smart. In essence, RTP is the percentage of the total amount of all bets that theoretically returns to players in the form of winnings over a long distance.
Imagine you are playing a slot with an RTP of 96%. This means that for every 100 rubles bet on this machine, players (on average and in the long run) get back 96 rubles in the form of winnings. The remaining 4 rubles make up the so-called "house edge".
Important to understand: RTP is a statistical indicator calculated over millions of spins. It does not guarantee that you will get back exactly 96% of your bets in a single gaming session. In the short term, the actual return percentage can deviate significantly from the stated RTP in either direction – and this is the very essence of gambling.
However, choosing slots with a high RTP mathematically increases your chances of winning in the long run. The difference between a machine with an RTP of 94% and 98% may seem insignificant, but over the long run, it's a huge amount of money.
For example, when playing with the same bets:
- In a slot with an RTP of 94%, you will theoretically lose 600 rubles for every 10,000 rubles
- In a slot with an RTP of 98%, the losses will be only 200 rubles from the same 10,000 rubles
A difference of 400 rubles – and that's only for 10,000 rubles of total bets! Now imagine how this affects the result of the game over months or years.
It should also be noted that RTP is directly related to the concept of slot dispersion (volatility), which we will discuss in more detail a little later. These two parameters together help to understand which machines are most profitable to play.

| Slot Name | Developer | RTP (%) | Volatility | Features |

Book of 99 – the absolute leader in payout
A real find for those hunting for slots with a high RTP is the Book of 99 machine from Relax Gaming with a record payout rate of 99%. This means that theoretically, players get back 99 kopecks for every ruble bet! Thematically, the slot is based on ancient Greek mythology, which makes the gameplay not only profitable but also exciting.
Book of 99: key features
- Record RTP of 99%
- Collecting book symbols (you need to collect 99)
- Free spins with an expanding symbol
- High volatility — a chance for big wins
- The ability to win up to 5000x the bet
The main feature of this machine is the collection of book symbols. When you collect 99 such symbols (hence the name), a free spins round with an expanding symbol is activated. This can lead to impressive wins, especially if you're lucky enough to get a high-paying hero symbol.
Note that the high RTP is combined here with high volatility – this means that wins can be rare but very significant. Players with a small bankroll should approach this slot with caution and smart money management.
1429 Uncharted Seas – a beautiful game with an amazing payout
This amazing slot from Thunderkick with an RTP of 98.6% takes players to the era of great sea discoveries. The game is designed in the style of old maps, and the animations and sound design create a unique atmosphere of adventure.
The main advantage of 1429 Uncharted Seas is its low volatility combined with a high RTP. This means that you will receive winnings quite often, although they may not be as large as in high-volatility slots.
Expanding wild symbols in the form of a ship and compass scatters that trigger up to 50 free spins make the gameplay dynamic and allow you to maintain a stable balance for a long time. Many professional players choose this slot specifically for wagering bonuses due to its generous mathematical model.
Blood Suckers – a classic with a vampire entourage
The legendary slot from NetEnt with an RTP of 98% remains one of the most popular slot machines with a high payout. The vampire theme, atmospheric graphics, and exciting bonus round attract both beginners and experienced players.
Blood Suckers is characterized by low volatility, which provides frequent, albeit small, wins. Combined with a high RTP, this makes the game ideal for those who prefer stability to sharp ups and downs of the balance.
The bonus game deserves special attention, where you have to open coffins and destroy vampires. Each vampire found brings a win, and the bonus round continues until you stumble upon an empty coffin. This game can bring up to 50x your bet, which makes Blood Suckers not only generous but also an extremely exciting slot.
Slot volatility: how this parameter affects your winnings
If RTP shows how much is returned to players on average, then volatility (or dispersion) determines HOW exactly these payouts occur. Understanding this parameter is critically important for choosing a slot that matches your gaming style and financial capabilities.
Low volatility: frequent small wins
Low-volatility slots are the ideal choice for players with a limited budget or those who prefer long gaming sessions without sharp balance fluctuations.
Features of low-volatility slots:
- Winnings fall out frequently, almost every 3-4 spins
- The size of the winnings is usually small – rarely exceeds 20-50x the bet
- The risk of quickly losing the entire bankroll is significantly lower
- The gameplay is more predictable and stable
- Great for wagering bonuses with betting requirements
In addition to the aforementioned 1429 Uncharted Seas and Blood Suckers, slots with low volatility and good RTP include Jack Hammer (RTP 97%), Starburst (RTP 96.1%), and Victorious (RTP 96.9%).
Medium volatility: a balance of risk and payout
Medium-volatility slots are the golden mean between frequent small wins and rare large ones. They are suitable for most players and provide a balanced gaming experience.
Characteristics of medium-volatility slots:
- Winnings occur with moderate frequency
- The size of payouts varies from small to quite impressive
- The balance can experience noticeable, but not critical, fluctuations
- The gameplay combines elements of stability and excitement
- A good option for players who have not yet decided on their preferences
Among the medium-volatility slots with a high RTP, we can highlight Jokerizer (RTP 98%), Marching Legions (RTP 98%), and Devils Delight (RTP 97.6%).
High volatility: rare but large wins
High-volatility slots are the choice of adrenaline lovers and hunters of big wins. Such machines can go "dry" for a long time but then suddenly give out a sum that is hundreds or even thousands of times the bet.
What you need to know about high-volatility slots:
- Winnings fall out rarely – you can spin dozens and even hundreds of times without significant payouts
- When a win does happen, it can be very large (100x, 500x, 1000x and higher)
- Require a solid bankroll for comfortable play
- High risk of quickly losing the entire deposit
- Suitable for patient players who are ready for a long "drought" for a chance at a big prize
Of the high-volatility slots with a decent RTP, you should pay attention to Book of 99 (RTP 99%), Mega Joker (RTP 99%), and White Rabbit (RTP 97.7%).
It is important to understand that volatility and RTP are independent parameters. A slot can have a high RTP and any level of volatility. The ideal choice depends on your personal preferences, bankroll size, and game goals.
Best slot providers with a high return percentage
The quality and fairness of a slot machine largely depend on its developer. Some providers are known for consistently releasing slots with a high RTP and transparent mechanics. Let's look at the most generous slot machine manufacturers.
NetEnt
A Swedish giant that has earned a reputation as one of the most reliable and innovative developers. The company's portfolio includes many slots with an RTP above 97%, including such hits as Mega Joker (RTP 99%), Blood Suckers (RTP 98%), and Kings of Chicago (RTP 97.8%). NetEnt is also known for its progressive jackpots, for example, Mega Fortune, which has repeatedly set records for the size of winnings.
Relax Gaming
A relatively young but ambitious provider that released the record holder of our rating – Book of 99 with an RTP of 99%. The company specializes in high-quality slots with innovative mechanics and often pleases players with machines with a high return percentage.
Thunderkick
A Swedish developer known for its creative and visually appealing slots. The company pays special attention to the mathematical models of its games and often offers an RTP above the industry average. A prime example is 1429 Uncharted Seas with an RTP of 98.6%.
Play'n GO
This developer balances a high RTP with exciting gameplay. Although the average RTP of their slots is slightly lower than the leaders on our list (around 96%), some machines stand out for their generosity – for example, Pearls of India with an RTP of 97.5%.
Yggdrasil
A provider known for its innovative mechanics and visual style. Jokerizer with an RTP of 98% is one of the most generous slots in their portfolio.
The table below shows the average RTP indicators for the main providers:
| Provider | Average RTP (%) | Best slot by RTP | RTP of the best slot (%) |
|---|---|---|---|
| NetEnt | 96.5 | Mega Joker | 99.0 |
| Relax Gaming | 96.4 | Book of 99 | 99.0 |
| Thunderkick | 96.3 | 1429 Uncharted Seas | 98.6 |
| Play'n GO | 96.2 | Pearls of India | 97.5 |
| Yggdrasil | 96.1 | Jokerizer | 98.0 |
| Pragmatic Play | 96.0 | 888 Dragons | 97.0 |
| Microgaming | 96.0 | Hot Ink | 97.5 |
When choosing a slot, it makes sense to first pay attention to machines from these time-tested developers. They not only guarantee a fair RTP but also provide high-quality gameplay, reliability, and security.
How to properly choose slots with a good payout: 5 main criteria
Choosing the right slot is a real art that requires taking into account many factors. In addition to the obvious RTP, there are a number of other criteria that should be paid attention to in order to maximize your chances of winning.
1. RTP is higher than the industry average
In the modern online gambling industry, the average RTP is about 96%. Accordingly, slots with a return percentage higher than this value can be considered relatively generous. But you should not chase only record holders – sometimes a slot with an RTP of 97% can be more profitable than a machine with an RTP of 99% due to other parameters.
2. Optimal volatility for your play style and bankroll
As we have already discussed, volatility determines the distribution of winnings. If your bankroll is limited, it is better to choose slots with low or medium volatility, even if their RTP is slightly lower. In the case of limited funds, a high-volatility slot with a high RTP may simply "eat up" your entire deposit before you get a significant win.
3. The presence and mechanics of bonus features
Modern slots offer many bonus features that can significantly affect the final profitability of the game:
- Free spins – especially valuable with multipliers or additional wild symbols
- Respins – repeated spins of individual reels
- Expanding or sticky wild symbols – can significantly increase the probability of forming winning combinations
- Multipliers – increase the size of the winnings several times
- Bonus games – often offer guaranteed winnings or a chance for a big prize
4. Payout structure
Study the slot's paytable before playing. Pay attention to the ratio between minimum and maximum winnings for combinations. A good slot should have a balanced payout structure – from small but frequent wins to rare but significant ones.
5. Developer reputation
Choose slots from proven providers who value their reputation and use certified random number generators. Companies like NetEnt, Microgaming, Yggdrasil, Play'n GO, and Thunderkick guarantee fair play and compliance with the stated RTP.
Additional factors to consider:
- Number of paylines or ways to win – in general, the more, the better (but not always)
- Minimum and maximum bets – they must match your bankroll
- Maximum possible win – some players prefer slots with a potential win of x1000 and higher
- Presence of a progressive jackpot – such slots usually have a lower base RTP, but can potentially bring a huge win
- The ability to buy a bonus game – this feature allows you to immediately get into the bonus round for a certain fee
Remember that the ideal slot is the one that matches your personal preferences, financial capabilities, and goals. Experiment with different machines in demo mode before playing for real money.
Common myths about high RTP slots
The world of gambling is full of misconceptions and superstitions, many of which concern high-payout slots. Let's debunk the most common myths and establish the truth.
Myth 1: "If a slot hasn't paid out for a long time, it means a big payout is coming soon"
This is probably the most common misconception among players. In fact, modern slots use random number generators (RNGs), which ensure the complete independence of each spin from the previous ones. The slot machine has no "memory" and does not take into account how much you have already lost. The probability of winning on the next spin remains unchanged regardless of whether the previous result was a win or not.
Myth 2: "Online casinos can arbitrarily change the RTP of slots"
Licensed online casinos do not have the ability to arbitrarily change the return percentage of slot machines. The RTP is set by the developer at the level of the game's source code, and licensing bodies regularly check the compliance of the stated indicators. The only exception is that some providers initially create several versions of the same slot with different RTPs, and the casino can choose which version to offer to players. However, after choosing a version, the casino can no longer interfere with the operation of the machine.
Myth 3: "Playing with the maximum bet increases the RTP"
In most modern slots, the RTP is the same for all bet sizes. However, there are exceptions, for example, Mega Joker from NetEnt, where the RTP really increases when playing at maximum bets. Such cases are usually explicitly stated in the game rules. If this is not stated, you can be sure that the return percentage does not depend on the size of the bet.
Myth 4: "Slots pay less after a big win"
Another common misconception. Modern licensed slots do not "cool down" after paying out a jackpot or another big win. Each spin is independent, and the probability of winning does not decrease due to previous results. The only exception is progressive jackpots, which are reset to their initial value after being paid out, but this only affects the size of the maximum prize, not the basic probability of winning.
Myth 5: "Demo versions of slots have a higher RTP to attract players"
Developers use the same RTP for both demo versions and real money play. Changing this parameter would be not only unethical but also illegal. Moreover, most demo versions use exactly the same code as the main game, just with the real betting function disabled.
Myth 6: "If you play by a certain 'system', you can beat any slot"
No betting system can change the built-in house edge in slots. Martingale, D'Alembert, Fibonacci – all these betting management systems can help structure the game, but are not able to overcome the mathematically embedded negative expected outcome. Remember: in the long run, the result will always tend towards the theoretical RTP.
Understanding these myths and the real principles of how slots work will help you make more informed decisions and get more enjoyment out of the game. Remember the main rule: the game should bring joy, not be perceived as a way to make money.
Strategies for playing high-payout slots
Although the result in slots is largely determined by luck, the proper application of some strategies can help maximize your chances of winning and extend the enjoyment of the game. Here are some proven approaches to playing high-RTP slots:
Bankroll management – the foundation of all strategies
Bankroll management is not just a fashionable phrase, but a truly important skill for any player. Here are the basic principles:
- Determine your gaming budget in advance – decide how much you are willing to spend and never exceed that amount
- Divide the bankroll into sessions – for example, if your monthly budget for the game is 10,000 rubles, you can allocate 1,000 rubles for each gaming session
- Adhere to the rule of 1-5% of the bankroll per spin – with a bankroll of 1,000 rubles, it is reasonable to make bets of no more than 10-50 rubles per spin
- Set winning and losing limits – for example, end the session when you reach +50% or -50% of the initial bankroll
Choosing volatility based on bankroll size
As we have already discussed, the volatility of a slot directly affects the gameplay:
Large bankroll + high volatility – with a solid amount, you can afford to "survive" long periods without winnings while waiting for large payouts
Small bankroll + low volatility – limited funds are better invested in slots with frequent, albeit small, wins to extend the game
Using casino bonuses and promotions
Modern online casinos offer many bonuses that, with proper use, can significantly increase your chances of winning:
- Deposit bonuses – increase your gaming bankroll
- Free spins – allow you to play without risk to your own funds
- Cashback – returns a portion of the lost money
- Slot tournaments – give you a chance to win additional prizes
When using bonuses, always carefully read the wagering requirements and choose slots with a high RTP for more effective wagering.
The "Up the Ladder" tactic
This strategy is especially effective for slots with medium and high volatility:
- Start with the minimum bet
- When you achieve a win that exceeds the initial bet by 1.5-2 times, increase the bet by one step
- If a series of unsuccessful spins leads to a loss of 20-30% of the bankroll, return to the previous bet size
- Continue to adjust the bet depending on the results
This approach allows you to maximize winnings during "hot" periods and minimize losses during "cold" ones.
The "Fixed number of spins" strategy
A simple but effective approach:
- Decide in advance how many spins you will make (for example, 100)
- Divide your bankroll by this number (for example, 1000 rubles ÷ 100 = 10 rubles per spin)
- Play for exactly the planned number of spins regardless of the result
- End the session and evaluate the results
This method helps to avoid emotional decisions and "tilt" (playing on emotions after a loss).
Proper use of autoplay
Many modern slots offer an autoplay function that can be customized with additional parameters:
- Loss limit – autoplay stops when a certain amount of losses is reached
- Win limit – the game stops at a big win
- Stop at bonus game – allows you to personally control potentially profitable bonus rounds
Properly setting these parameters will help you implement your game strategy without the need for constant control.
Remember that no strategy guarantees a win in slots – ultimately, the result is determined by luck and the built-in RTP. However, these approaches will help you play more consciously, extend the enjoyment of the game, and potentially increase your chances of a positive outcome.

Play at VavadaHow to check the real RTP of a slot machine
Despite the fact that developers and casinos state certain RTP indicators, it is sometimes useful to independently check how they correspond to reality. Here are a few ways to do this:
Official information from the developer
The easiest way is to visit the provider's official website and find data on the slot you are interested in. Large developers such as NetEnt, Microgaming, Play'n GO, and others usually publish information about the RTP of all their games. This data can be considered the most reliable, as it is checked by independent laboratories (for example, eCOGRA or iTech Labs) and regulatory bodies.
Information inside the slot itself
Most modern slot machines contain information about the RTP in the game rules or paytable. This information can usually be found by clicking on the "i", "Help", "Paytable", or "Rules" button in the slot interface. If a range is indicated there (for example, 94-97%), this may mean that the slot has several versions with different RTPs, or that the indicator changes depending on the game settings.
Independent calculation on a large sample
This method requires time and patience but allows you to get an idea of the real payout of the machine:
- Start with a certain amount (for example, 10,000 rubles)
- Make monotonous bets (for example, 10 rubles per spin)
- Make at least 1000 spins, recording each result
- After the series, calculate the actual RTP using the formula:
RTP = (Total winnings ÷ Total bets) × 100%
The more spins you make, the more accurate the result will be. However, remember that even 1000 spins is a relatively small sample, and the actual result can differ significantly from the theoretical RTP. For statistically significant results, tens or even hundreds of thousands of spins are required.
Checking country restrictions
Some developers create different versions of the same slot with different RTPs for different jurisdictions. For example, the UK and Sweden have stricter requirements for minimum RTP than some other countries. Compare the indicators for your region with those for the UK – if there is a significant difference, you may want to look for another slot.
Tracking and statistics tools
There are specialized programs and browser extensions that help you track your gaming statistics, including the actual RTP. These tools are especially useful for professional players who spend a lot of time playing and want to get accurate data about their results.
Reviews and reviews from other players
Forums, specialized sites, and player communities often publish information about the actual payout of various slots based on extensive gaming experience. Although this data is subjective and not always accurate, it can give a general idea of whether the real payout corresponds to the stated RTP.
Remember that even with a perfectly fair game, your personal results can differ significantly from the theoretical RTP due to natural variability and a limited number of spins. Only in the long run (millions of spins) will the actual result approach the stated return percentage.
Real stories of big wins in high RTP slots
A high RTP is not just a theoretical concept. The history of online casinos knows many cases when players received truly impressive winnings in slots with a good payout. Here are a few real stories that confirm that sometimes luck really smiles on players.
Record win in Mega Moolah
In September 2018, an anonymous player from Europe hit a jackpot of €18.9 million (about 1.5 billion rubles) in the Mega Moolah slot from Microgaming. This win still holds the world record for the size of an online jackpot. Interestingly, the base RTP of Mega Moolah is only 88.12%, but taking into account the progressive jackpot, this indicator increases to 96-97%. The story of this win is especially amazing because the lucky player made a bet of only €0.75 (about 60 rubles)!
Finnish player and NetEnt's Mega Fortune
In 2013, a player from Finland, who wished to remain anonymous, won €17.8 million (about 1.4 billion rubles) in the Mega Fortune slot from NetEnt. This machine has a base RTP of 96.6%, which is higher than the industry average. It is noteworthy that before this win, the Finn had been playing at an online casino for only a few weeks and that evening he was making bets of only €0.25 (about 20 rubles).
Big win in Book of 99
In June 2021, a player from Russia won more than €150,000 (about 12 million rubles) in the Book of 99 slot from Relax Gaming – the very one that tops our rating with an RTP of 99%. The game was played at medium bets (€2-5), and a big win happened during the free spins bonus round when the expanding hero symbol filled all the reels. The story of this win confirms that a high RTP combined with luck can bring truly impressive results.
Blood Suckers and a series of consecutive wins
In 2019, a player with the nickname MaxWin shared his story of playing Blood Suckers (RTP 98%) on a forum. Starting with a deposit of $500 (about 37,000 rubles), he increased his bankroll to $12,000 (about 890,000 rubles) in a few hours. The key moment was a series of five consecutive bonus game launches, each of which brought a win 20-30 times the bet. This story shows how a low-volatility slot with a high RTP can ensure a stable bankroll growth under favorable circumstances.
Jackpot in Jokerizer
In February 2018, a player from Sweden won €80,000 (about 6.5 million rubles) in the Jokerizer slot from Yggdrasil (RTP 98%) with a bet of only €2 (about 160 rubles). The win happened in Jokerizer mode when three joker symbols fell on the central reels, activating a Mystery Win with a maximum multiplier. This case demonstrates how a medium-volatility slot with a high RTP can lead to an unexpectedly large win.
Series of wins in 1429 Uncharted Seas
In January 2020, a professional gambling streamer documented his experience playing 1429 Uncharted Seas (RTP 98.6%). During a five-hour session, he started with $1000 (about 74,000 rubles) and ended with a balance of over $5000 (about 370,000 rubles). The key to success was repeatedly getting the maximum number of free spins (50) and expanding wild symbols, which regularly brought wins 50-100 times the bet.
These stories confirm that choosing slots with a high RTP can indeed lead to significant wins. However, it is important to remember that these cases are the exception rather than the rule. For every success story, there are thousands of players who have not received significant wins. Playing slots is always associated with risk, and even high-RTP machines do not guarantee a positive result.
What to pay attention to when choosing an online casino for playing slots
Even the most generous slot with a high RTP will not be of any use if you play at an unreliable online casino. Here are the key criteria to pay attention to when choosing a platform for playing:
License and regulation
Having a valid license from a reputable regulator is the first and most important indicator of a casino's reliability. The most respected licensing bodies include:
- Malta Gaming Authority (MGA)
- UK Gambling Commission (UKGC)
- Gibraltar Regulatory Authority
- Isle of Man Gambling Supervision Commission
- Alderney Gambling Control Commission
- Curaçao eGaming
Information about the license is usually located at the bottom of the main page of the site. Be sure to check the relevance of the license and the reputation of the regulator.
Confirmed game fairness
Reliable casinos cooperate with independent auditing organizations that check and confirm the fairness of games and compliance with the stated RTP. Look for the logos and certificates of such organizations on the casino website as:
- eCOGRA
- iTech Labs
- GLI (Gaming Laboratories International)
- BMM Testlabs
Speed and ease of withdrawing funds
The ease of receiving your winnings is a critical factor. Pay attention to:
- Available withdrawal methods
- Minimum and maximum withdrawal amounts
- Application processing speed
- Presence of commissions
- Verification requirements
The best casinos process withdrawal requests within 24 hours and offer a variety of ways to receive winnings.
Reputation and reviews
Research the casino's reputation on specialized forums and review sites. Pay attention not only to the rating, but also to specific comments about:
- Payout speed
- Service quality
- Resolution of disputed situations
- Experience of players with big wins
Quality of customer support
A good casino offers round-the-clock support in several languages through various communication channels:
- Live chat
- Phone
- Social media
Check the work of the support service by asking a few questions before registering.
Bonus program and conditions
Bonuses can significantly increase your gaming bankroll, but it is important to pay attention to the conditions:
- Wagering requirements
- Maximum bet size with an active bonus
- List of allowed games
- Bonus validity period
- Maximum winning amount from bonus funds
Overly attractive bonuses are often accompanied by impossible conditions, so carefully read all the rules.
Availability of your favorite slots
Make sure that the casino cooperates with the developers of your favorite slots, especially those that have a high RTP. The variety of providers usually indicates the solidity of the casino.
Ease of use and mobile version
A modern casino should offer an intuitive interface and full functionality on mobile devices:
- Responsive design or a separate mobile app
- Fast game loading
- Convenient navigation
- Simple filtering and searching for slots
Responsible gambling
Reliable casinos support the principles of responsible gambling and offer tools for self-control:
- The ability to set deposit limits
- Self-exclusion options
- Time-outs
- Self-assessment of problem gambling
The table below shows the main criteria for choosing a reliable online casino:
| Criterion | What to pay attention to | Red flags |
|---|---|---|
| License | Reputable regulators (MGA, UKGC) | Lack of a license or a license from an unknown regulator |
| Fairness check | eCOGRA, iTech Labs certificates | Lack of independent audits |
| Payouts | Withdrawal speed < 24 hours | Long delays, high commissions |
| Reputation | Positive reviews, quick dispute resolution | Stories about non-payment of large winnings |
| Support | 24/7, multiple communication channels | Email only, long waiting time for a response |
| Bonuses | Reasonable wagering requirements (x25-x40) | Wagering x50 and higher, many restrictions |
| Assortment | Various providers, including top ones | Only little-known developers |
| Security | SSL encryption, 2FA | Unprotected connection |
Choosing a reliable casino is just as important as choosing slots with a high RTP. Ultimately, even the most generous slot machine will not bring joy if you cannot get your winnings.
Frequently asked questions about high-payout slots
RTP (Return to Player) is the percentage of the total amount of bets that theoretically returns to players in the form of winnings over a long distance. For example, if a slot's RTP is 96%, it means that for every 100 rubles bet on this machine, players get back 96 rubles on average.
It is important to understand that RTP is calculated over millions of spins and does not guarantee a specific result in the short term. However, choosing slots with a higher RTP mathematically increases your chances of a positive outcome and reduces the casino's advantage.
Yes, you can win in any slot, regardless of its RTP. The return percentage is a statistical indicator that only manifests itself over a large number of spins. In the short term, the result is determined primarily by luck.
Even in a slot with a low RTP (for example, 90%), you can get a big win, and in a slot with a high RTP (98%) – lose. However, the higher the RTP, the better your chances of a positive outcome in the long run.
It all depends on your goals. Slots with progressive jackpots usually have a lower base RTP (part of the bets goes to the jackpot), but offer a chance for a really big win. Such machines are suitable for players who dream of a life-changing prize and are willing to take risks.
Slots with a high RTP but without a progressive jackpot provide a more stable game and better chances of a positive result over the long term. They are ideal for players who want to extend the enjoyment of the game and minimize losses.
The RTP of a slot is usually set by the developer at creation and does not change during the game's life cycle. However, some providers create several versions of the same slot with different RTPs for different markets or casinos.
Information about the RTP is published by the developers when the game is released and is updated only in the event of significant changes in the machine's mechanics. If you notice a change in the stated RTP of a slot, it is better to contact the casino's support service or the developer for clarification.
In most modern slots, the RTP does not depend on the bet size – the return percentage is the same for both minimum and maximum bets. However, there are exceptions:
- Some NetEnt slots (for example, Mega Joker) have an increased RTP when playing at maximum bets
- In slots with a "bonus buy" function, the RTP may differ when this option is activated
- Some classic slots with special mechanics may have a different RTP for different bet sizes
Information about the dependence of RTP on bet size is usually indicated in the game rules.
Licensed casinos do not have the technical ability to independently change the RTP of games, as these parameters are set at the source code level by the developer. However, some providers offer several versions of the same game with different RTPs, and the casino can choose which version to provide to players.
To protect yourself, choose casinos with a good reputation and licenses from reputable regulators who require the publication of accurate information about the RTP of games.
The most reliable sources of information about RTP:
- The developer's official website
- The information section (help, info, paytable) inside the slot itself
- Official press releases about the game's release
- Specialized independent resources dedicated to slot reviews
Avoid unverified sources, as they may contain outdated or unreliable information.
