A slot’s RTP directly impacts your long-term winning potential. If you’ve ever wondered why some slots seem to pay out more consistently than others, the answer often lies in a metric called Return to Player (RTP). In fact, there are no slots which guarantee profits as the RTP is always below 100%. Our pick of the bunch is Casumo Casino which has a fantastic selection of high RTP slot machines you can play. Therefore, Book of 99 is the highest RTP slot game available.
ALWAYS check the actual RTP in the game before playing—don’t assume it’s the highest version! Some providers (Playtech, IGT, certain Pragmatic Play games) offer multiple RTP versions of the same game. Only 23 online slots achieve the ultra-rare 99%+ RTP threshold. By law, reputable providers must list the theoretical RTP of the specific version you are playing.
One of the top online slot releases thanks to its high RTP, large max payout and amazing gameplay, Blood Suckers Megaways is one of Red Tiger’s best releases in a long time. We recommend playing at Dream Vegas casino where you can help yourself to both free spins and a matched deposit bonus. We also give you details on how to play these high RTP slot games as well as were you can play them in February 2026. High RTP slots often have lower max win caps or more frequent, smaller payouts.
The Future of RTP Tracking and Databases
From high RTP Megaways slots to new Everyway slots, Red Tiger Gaming continue to revolutionise the slots market in numerous ways.

Bonus Features
RTP isn’t just a technical term, it’s a critical factor in shaping your gaming experience. For example, a slot with 96% RTP will, theoretically, give back $96 for every $100 wagered in the long run. A slot with an RTP above 97% we consider as a high RTP slot. The slot with the highest RTP is Ugga Bugga by Playtech with 99.07% RTP, but it is not currently widely available. So, for every £100 you put into the slot, you will get back £99.00.
However, a high RTP does not necessarily guarantee a winning session. We have already explained RTP, let’s now explain volatility in nutshell. Players often mistake volatility/variance for RTP and vice versa.
To pick the right slot for your bankroll, you must understand how RTP, Volatility, and Max Win pull against each other. However, in our casino reviews above, you will see us mention various performance metrics. Our table above lists the Slot RTP, which is the mathematical return programmed by the developer.
