Online slot RTP rates can range from as low as 85% up to 99%. However, the average RTP for online slots stands at 96%.
That means anything 97% and up should be considered “high.” Thus, all of the slots on our list of the highest RTP slots online qualify.
RTP tells you the percentage of all the money put into a slot that the game will pay back to players as winnings over time. But it’s no guarantee of how any individual session will go.
Play a slot with a 97% RTP, and 97 cents of every dollar put into it will be paid back to players as wins over time, but that doesn’t necessarily mean you’re going to get 97 cents of every dollar you personally put into the slot.
Still, playing higher RTP slots is a logical thing to do. Higher RTP means a better chance for all players to win— or lose less, at the very least.
Google it, look online, or around this website, as we list the RTP for a ton of online slots. Also, most online casinos are upfront about it, publishing a slot’s RTP under the italic ‘i’ symbol on any online slot’s game tile.
Maximizing your play on high RTP slots is almost always about maximizing your bet. Unless otherwise stated, betting the max gives you a better chance to win and helps you realize a slot’s true RTP.
Betting the max can also be the key to unlocking bonus games and your chance to win the game’s top prize.
Unless otherwise stated in the terms and conditions of a bonus, you can play high RTP slots to clear any wagering requirements attached to that bonus. In fact, playing high RTP slots is the best way to clear wagering requirements.
You’ll have to get lucky if the bonus will have any value, even with just a one-time wagering requirement. However, high RTP slots give you one of the best chances to do just that.
Nowadays, almost every slot you can play on an online casino website is available on its Android and iOS apps. This includes High RTP slots. You may have fewer slot options on the apps, but you can be assured any missing slot is on the way and should be available for mobile play before long.
The graphics might be slightly different, as mobile games are optimized for small screens, but the gameplay and RTP are always the same, whether you play a slot on a website or a mobile casino app.
Online slots are about having fun. You might get lucky and win, but the chances are you won’t, even playing high RTP slots. The losses should be considered the cost of your good time, and anything you win is an extra bonus from an entertaining experience.
Keeping it all entertaining means following responsible gambling practices, like never betting more than you can afford to lose, setting limits, and sticking to them.
If your slot play ceases to become fun or you suffer financial, relationship, employment, or health hardships as a result of it, seek help. We recommend the resources available through national organizations like:
