Highest RTP Slots

Slots

The average RTP in our database is 95.64%. But there are games that pay out two or three percent more, and a few that approach 99%. We cross-referenced the industry's well-known records with providers' official data and compiled what can actually be opened and spun.

Record Holders: 98% and Above

Game Studio RTP Volatility
Goblin's Cave Playtech 99.32% Low
Ugga Bugga Playtech 99.07% Low
Mega Joker NetEnt 99.00% Low
Book of 99 Relax Gaming 99.00% Medium

Thunder vs Underworld Pragmatic Play 98.04% Very High
Blood Suckers NetEnt 98.00% Low

Goblin's Cave has held the absolute record since the 2000s, but it's hard to find: it has disappeared from some regulated markets, including the British one. Book of 99 and 1429 Uncharted Seas are not yet in our catalog — we haven't connected these studios yet.

Half of These Numbers Have an Asterisk

Classics like Mega Joker and Jackpot 6000 show their 99% and 98.9% only in supermeter mode and with a maximum bet. If you play with a small bet in normal mode, the actual payout is significantly lower than stated. The provider doesn't hide this, they just write it in small print in the rules. Ugga Bugga is also a game from the 2000s, with a hold mechanic on ten reels. The number is honest, but the game itself looks its age: no cascades, bonus buys, or animations. Hence the rule: if you see an RTP above 98%, open the rules and see if there are any conditions. Modern releases usually don't have them; old slots almost always do.

What's Available from Modern Games

The highest payout among new games is from Pragmatic Play. Thunder vs Underworld with 98.04%, The Dog House – No Dog Left Behind with 98.02%, and Lucky Phoenix with exactly 98%. No conditions, any bet size. But all three have maximum volatility. And this is no coincidence. Next to them on the list is Novibet Sugar Rush 1000 with 97.5% — a build made for a specific casino. Providers regularly release such versions: the game is the same, but the payout differs from the base one. This is the best reminder that a number from someone else's review guarantees nothing until you see it in the game menu on your own site.

High RTP Usually Means Wild Swings

There are a total of 40 games in the catalog with an official RTP of 97% or more. Of these, eighteen have very high volatility, almost half. The logic is simple. Payout can be increased in two ways: pay more often or pay larger amounts. Modern studios choose the latter because it makes the game more interesting. As a result, 98% RTP is accumulated from rare big wins, between which lie hundreds of empty spins. With a small bankroll, you won't see these percentages — your money will run out sooner. Old slots like Blood Suckers and Jackpot 6000 are structured differently. There are no bonus buys or full-screen multipliers, but small payouts are constant, and the bankroll dwindles slowly. Boring, but it honestly delivers the stated percentages even in a short session.

Goblins Cave You can check this in a simulator: take Thunder vs Underworld and Blood Suckers with almost identical RTP and run a thousand spins. The curves will look like graphs from different universes.
