Highest RTP slots right now

What is slot RTP and how is it calculated?

When you play an online slot at a legal real money casino, the RTP percentage is built into the way the game is programmed. Known as the return to player percentage, it’s the theoretical return to players over time. It gives you an idea of how the slot pays out over time but also allows you to plan ahead based on how your session is going and whether or not you’ve had a big win that would tilt the scales in your favor.

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.

The highest RTP online slots have RTP percentages over 96 percent.

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.

What is considered a good RTP percentage for slots?

When considering what a good return-to-player percentage is, keep in mind that the majority of online slots average around a 96% RTP. Anything above that would be considered good in comparison, and the ones you’ll find featured here are usually 97% or higher.

You’ll notice that some of the most popular progressive jackpot slots will typically have a lower-than-average RTP since there is a chance to win a bigger jackpot the more you play.

In addition to your personal entertainment reasons as to why you’d choose to play a certain slot, reviewing its RTP percentage before you play can help you choose the best ones for you. The higher the slot’s RTP, the more you can theoretically expect to win.

Sweepstakes casinos provide an experience similar to real money casinos and operate in most states thanks to sweepstakes laws.

These casinos do not allow players to win real money by playing games. Instead, sweeps casinos utilize two forms of virtual currencies: Gold Coins and Sweepstakes Coins.

High RTP Slots FAQ

What does RTP stand for?

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.

Which slots have the highest RTP percentages?

The highest RTP slots include Mega Joker (99%), Blood Suckers (98%), Starmania (97.86%) and White Rabbit Megaways (97.72%). Most online slots are near 96 percent for RTP.

How do I find an online slot’s 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.

Do high RTP slots pay out more than other slots?

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.

What does a 96% RTP signify?

An RTP percentage of 96 indicates that, on average, for every $100 wagered, $96 would be returned to the player. All slots have an RTP percentage built into its programming. High RTP slots have RTP percentages abover 96.

Is it more advantageous to play slots with a high RTP or a low RTP?

Always play slots with a high RTP. The higher a slot’s RTP, the more money you can expect to win in the long run. Low RTP slots return less money to players than high RTP slots.

How can I verify if the RTP of my slot machine is accurate?

Most online casinos will reveal a slot game’s RTP in the game’s “Information” section. If you can’t find a slot’s RTP, reach out to the casino’s customer support and ask. You also can find many slots’ RTP percentages on the website of the game’s developer.

Are the RTPs of online slots different from those of physical slot machines?

In most instances, the RTPs for online slots are higher than those for physical slot machines because the cost to maintain and operate physical slot machines are higher.
