Highest Slots to Play in 2025
Players often search for the highest RTP slots, which is one of the main aspects of the best gaming experience. Some important factors are the maximum payout, volatility, bonus rounds, and betting limits. Continue reading our guide to understand what RTP stands for and discover online slots with the highest RTP percentages.
What Is RTP and Why Is It Important?
The return to player (RTP) rate of an online slot or casino game refers to the wagered amount of money players can expect to get back in the long run. As the house edge is low, the highest RTP slot games offer better chances of winning. The average RTP percentage for slots is considered 96%; therefore, titles with RTP rates above 96% are categorised as high-RTP games. While slots with jackpots offer the biggest prizes, they usually have lower RTPs.
Key Features of High RTP Slots
A slot machine can be considered “high” in different aspects. The key features we pay attention to when finding the best RTP slots include the theoretical percentage, maximum win, and betting limits. The following sections explain each feature.
High RTP Slots
Any slot machine with an RTP above the industry average of 96% has a reasonable theoretical payout. Generally, the highest RTP slots have payout percentages of 97%, 98%, and 99%.
High Volatility Slots
Understanding volatility is as important as knowing the slot RTP. Slots with high-volatility games are characterised by infrequent wins, but players can win substantial sums in a short time. Such a game is best suited for gamblers who take risks for better payouts.
Highest Max Win Slots
Not every popular slot game available at casinos offers the best payout. The maximum win amount varies from one slot to another. For example, a high maximum payout slot machine may have a win potential of 10,000 times the stake or feature a jackpot.
Slots with High Stakes Betting Limits
Some of the highest RTP slot games are created with a wide betting range to meet the diverse needs of different players. In high-stakes slots, high rollers can bet €100 or more per spin. Such games are suitable for players with a larger gaming budget.
What Slots Have the Highest RTP in 2025?
Playing the best RTP slots can be advantageous, and the available options depend on the selected casino. Certain slots like Mega Joker by NetEnt and Book of 99 by Relax Gaming have an RTP of 99%, meaning the house edge is only 1%. Other popular games have payout percentages ranging from 97% to 98%. We have listed the top choices below.
| Slot Name | Developer | RTP | Volatility | Casino to Play | Release Year |
|---|---|---|---|---|---|
| Book of 99 | Relax Gaming | 99% | High | Ybets | 2021 |
| Mega Joker | NetEnt | 99% | High | Amonbet | 2011 |
| Blood Suckers | Red Tiger | 98% | Low | Wazbee | 2013 |
| Gold Train | Pragmatic Play | 97.16% | Medium | MrPacho | 2017 |
| Halloween Fortune | Playtech | 97.06% | Medium | MrPunter | 2012 |
Is Playing High RTP Slots Always the Best Choice?
A high slot RTP on its own does not necessarily guarantee a fulfilling gaming experience. Players must consider other factors, such as volatility, preferences, themes, and bonus rounds, when selecting games. We must also mention that many online casinos exclude the best RTP slots from deposit match bonus offers, free spins, and other promotions. When this happens, players may need to play RTPs with low rates to claim bonuses.

Important Elements of the Best Slots with Highest RTP
Finding a slot with the highest RTP involves checking for the most important elements while keeping the player’s preferences in mind. Slot games differ in terms of theme, symbols, number of paylines or ways to win, and bonus features. Players should consider the following factors when choosing slots with the biggest payout percentages.
Paylines
The number of ways to win varies from one slot machine to another. Classic slots usually have 1 to 3 paylines where players need to land matching symbols to win. On the other hand, modern slot games such as video slots, Megaways slots, and jackpot slots have tens to thousands of paylines. Many paylines offer more opportunities to land winning combinations.
Volatility
Volatility in slot games determines the frequency of wins and the risk associated with playing a particular game. If a slot is highly volatile, the player’s chances of landing a winning combination are low, but it is possible to hit a big win with a few spins. In contrast, low-volatility slot machines pay out frequently, but the win amounts are usually small.
Bonus Features
The best RTP slots attract players with rewarding features in the base game and bonus rounds. For example, slot fans can choose from titles with bonus reels, random wilds, tumbling reels, jackpots, free spins, feature drops, and a gamble feature. When selecting games from a particular developer, it is important to consider these and other innovative features.
Betting Options
A slot’s betting range and maximum win are important elements every player should focus on when choosing high RTP games. Depending on their preferences, players should be able to place both small and large bets. Moreover, the maximum payout amount should be good enough even when placing the lowest bet.
