One of the most important things to know when playing online slots is the RTP (Return to Player) percentage of each game you play.
Not every slot is created equal, and a big reason is that they all have different RTP percentages. Some pay less, and some pay more. Real money online casinos crave a large customer base so they will all have plenty of slots with high RTP percentages.
Note: If you access this page from a state without legal online casinos, you’ll see a list of sweepstakes and social casinos, which are legal in most states (excl. MI, ID, WA).
Every slot has an RTP percentage built into its programming. That percentage is the slot’s theoretical return to the player. In other words, it’s what the player can expect, on average, to win while playing the game.
If a game has a 96 percent RTP then for every $100 wagered, players should win an average of $96.There is no guarantee that the player will win that percentage. Rather, it is the percentage expected to be paid out to all players in the long term.
If you subtract a slot’s RTP percentage from 100, you get the “house edge.” In the above example, the house edge on that game is 4 percent.
Other casino games have RTP percentages, too, although a certain level of skill is calculated into it as opposed to the higher luck factor involved with slots. If you play blackjack following a basic strategy, you can achieve an RTP percentage of close to 99 percent. In addition to skill level, house rules factor into the RTP on blackjack. Meanwhile, most bets in American Roulette offer the same RTP percentage of 94.74 percent.
Without any other knowledge, if you were asked to guess the RTP of a given slot, you should guess 96 percent because most RTPs are in that range.
So, if you can find a slot with an RTP percentage of 97 or above, you’ve discovered a high RTP slot. Some are as high as 99 percent.
Slots with progressive jackpots typically have lower RTP percentages to make up for the potentially huge payout of the progressive jackpot.
Review a slot’s RTP percentage before you play. The higher the slot’s RTP, the more you can theoretically expect to win.

Mega Joker, which debuted over a decade ago, may only have three reels and three rows but don’t be fooled by its simplicity. Its 99 percent RTP is the best in the business.
It boasts a bonus Supermeter game plus a progressive jackpot. If you hit the Mega Joke you’ll be swimming in a payout of 2,000 times your stake.

All of the top online casinos are happy to offer Starmania because of its unique outer space theme flush with bright stars and effective 3D animation.
Play all 10 paylines for 20 chances to win. The path to maximizing your payout (500 times your stake) is to use the “gamble” feature for several opportunities to maximize your wins.
White Rabbit Megaways slot (Screenshot)White Rabbit Megaways
It’s easy to get caught up in this Lewis Carroll-themed slot with hints of his famous Alice in Wonderland. It also stands out because of the wider-than-normal game board. Up to 12 symbols can be featured on each line. What’s more, because it has so many paylines, there are up to 248,000 ways to win on every spin.
White Rabbit boasts wilds, bonus wilds, free spins, feature drops and scatters. Look for the caterpillar because the little critter brings multiple bonus wild symbols.

In addition to its high RTP, Medusa Megaways gives users some standout themes and a customizable game experience. You can choose anywhere from two to seven rows to go with the six reels to adjust the number of ways there are to win (324 to 117,000) on each spin.
There is no shortage of bonuses, either. There are free spins and multipliers as well as free games within the game. If you like big scores, you’re in luck because the maximum jackpot is 50,000 times your wager.
Secrets of Atlantis Slot (Screenshot)Secrets of Atlantis
Go for a swim deep in the sea while playing Secrets of Atlantis. It’s a fitting theme for a slot that can payoff at 4,000 times your stake because you might need to cool off when you hit it.
The deep sea theme brings all of the underwater creatures you can handle, such as mermaids, turtles, crabs and jellyfish. The 40 paylines pay both ways so there are 80 ways to win.
If you want to maximize your profit, bet at Level 10 and land five Oyster’s Pearls on one payline.

Reel Rush online slot (Screenshot)Reel Rush
This slot is great for dessert loves as the candy-theme design has five reels with a 1-3-5-3-1 row format. That’s not the limit, though. The more spins you win, the more rows you open up.
If you win five in a row, you’ll open the full 5 by 5 grid. If you make it that far, you’ll have 3,125 ways to win. A bonus if you reach that stage is the change in the music. It starts slow but speeds up as you get closer to the biggest win.
The games on our top 10 list are far from the only high RTP slots in the US. All of the top licensed and regulated online casinos boast hundreds of options when it comes to slots. Here are some other online slots with notably high RTP percentages worth looking out for.
Whenever you play online slots or 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.
RTP stands for “return to player” and is almost always listed as 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 can players expect to win on average? If a slot has an RTP of 97 percent, it is programmed to pay $97 of every $100 wagered. This number is for all players over time, so an individual player cannot expect to receive exactly 97 percent. Some will win less. Some will win more.
The best RTP slots include Mega Joker (99 percent), Codex of Fortune (98 percent) and Starmania (97.87 percent). Most online slots are near 96 percent for RTP.
Open an online slot and look for a spot in the corners to click and view information on the game. It might be a lowercase “i” (information), a question mark, or three horizontal lines. That information will tell you what the symbols mean, the payline structure, how to adjust your bets and the game’s RTP percentage.
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 and others won’t.
