With a Lewis Carroll-inspired theme, White Rabbit Megaways from Big Time Gaming is a high-volatility slot that features a unique design.

An incredibly dynamic slot, White Rabbit offers wilds, bonus wilds, scatters, free spins, feature drops, a free games feature, and the chance at winning approximately 13,000x the stake. Watch for the caterpillar that brings multiple bonus wild symbols whenever it crawls out.

Medusa Megaways, a Megaways version of the popular NextGen/SG Digital Medusa game, is another feature-rich, high-RTP slot. With a Greek mythology theme and high volatility, this unique six-reel, two-to-seven flexible row game gives you between 324 and 117,649 ways to win on every spin. Look for the replicating Medusa wilds, cascading symbols, free spins multipliers, and more. There are multiple in-game bonus features, too, including free games. It’s all useful to you as you try for the maximum jackpot of 50,000x the wager.
6. Secrets of Atlantis — 97.07% RTP
Secrets of Atlantis from NetEnt is a very popular slot with a cool underwater theme replete with mermaids, sea creatures, and chances to win riches if you can capture the gems and pearls among all the crabs, turtles, and jellyfish.

10. Reel Rush — 97% RTP
NetEnt’s Reel Rush is a candy-themed, medium-volatility slot with a throwback feel and a fun design. There are five reels with a 1-3-5-3-1 row format, but winning spins open up more spots on each reel while also awarding respins. Five wins in a row open up the entire 5×5 grid, which in turn means there are 3,125 different ways to win as the normally soft ambient music ramps up to match the player’s rise in adrenaline. Reel Rush features a maximum payout of 1,000x.
The high RTP slots listed above are readily found at major licensed and regulated online casinos in the US. There are other online slots with notably high RTP percentages worth looking out for as well. Some of these include Basketball Star (98.7%), Flaming Chillies (97.94%), and Ultra Stack Feature Rose (97.93%).

What Is Slot RTP and How Is It Calculated?
Every slot has an RTP (or return to player) percentage built into its programming. The RTP percentage equals the game’s theoretical return to the player, meaning what the player can on average expect to win while playing the game.
Let’s say a slot features a 96% RTP. That means for every $100 wagered on the slot, players should win an average of $96. That doesn’t mean a player will always win $96 for every $100 wagered, just that the game can be expected to pay out at that rate over the long term. Incidentally, if you subtract a slot’s RTP percentage from 100, you get the “house edge” in that particular game. In the above example, the house edge is 4%.
Other casino games have their own RTP percentages. If you play blackjack following a basic strategy, you can achieve a very high RTP percentage of close to 99% or even higher (depending on the house rules). Meanwhile, most bets in American Roulette offer the same RTP percentage of 94.74%.
What is considered a good RTP percentage for slots?
For online slots, many games hover right around 96% RTP, meaning if you find games that are 97% or 98% RTP (or higher), you’ve found relatively high RTP slots. Note that slots featuring progressive jackpots often have lower RTP percentages, but the potentially big payout up top helps increase the game’s overall theoretical return.
Definitely take the time to check out an online slot’s RTP percentage before playing it. Remember the higher the slot’s RTP, the more you can (theoretically) expect to win.
Increase Your Win Potential with High RTP Slots
Choosing slots with higher return-to-player percentages can help increase your chances of winning, although be aware the RTP percentage represents a theoretical return, not an actual (or guaranteed) return.
On average you should win a bit more by sticking with high RTP slots, but your results in any individual session may differ greatly from what the RTP percentage indicates. The slot may have a 97% RTP, but that doesn’t mean you’ll always get back $97 from every $100 you wager on it. In fact, you’ll likely win more or less than $97 in a single session.
Remember that other factors affect your results when playing slots. If it is a progressive slot, the RTP percentage might be low, but the chance at a big prize impacts the game’s theoretical return. The volatility of the slot also matters, with high-volatility slots usually paying out larger wins less frequently and low-volatility slots paying smaller wins more frequently.
In any case, check those RTP percentages before you play and be an informed slot player. Take advantage of high RTP slots when you find them.
Gamble Responsibly
Whenever you play online slots or engage in any other form of real money gambling, always use moderation and practice responsible gambling. Never play slots with money you cannot afford to lose, and always be on the lookout for signs of problem gambling.
There are many resources for learning more about responsible gambling or treating problem gambling. The National Center for Responsible Gambling and Gamblers Anonymous sites each share lots of information about how to get in touch with local resources in your state.
High RTP Slots FAQ
When you play slots (or any other casino game), you may encounter the acronym RTP which stands for “return to player” and usually refers to a percentage. The RTP percentage of a slot or casino game represents the theoretical return a player will receive while playing—in other words, how much the player can expect to win on average (but not in any one session). The RTP percentage represents what the slot is programmed to payout over the long term, meaning if it has a 96% RTP, it will over the long term pay $96 in winnings for every $100 wagered.
As noted above, slots like Mega Joker (99%), Codex of Fortune (98%), and Starmania (97.87%) rank among the highest RTP percentage slots.
You’ll find most online slots hover right around the 96% mark for RTP. That means slots with RTP percentages higher than 96% can be considered higher than average. Sometimes progressive jackpot slots will have lower RTP percentages, with the chance of winning big jackpots making up the difference.
After you’ve opened an online slot, you’ll typically see (in one of the corners) a way to click and view information about the game, including details concerning what symbols mean, the payline structure, how to adjust your bets, and the game’s RTP percentage. You might have to click a lowercase “i” (for information), a question mark, or the “hamburger” icon (three horizontal lines) that takes you to a menu of options. Some sites let you read detailed information (including the RTP) about slots before you open them.
Over the long term, slots with higher RTP percentages do pay out more than those with lower RTP percentages. That said, there is no guarantee you’ll win more playing a high-RTP slot during any given session. The results are randomized, meaning some players will win when they play and others won’t, just as some spins produce winners and others do not.
