What Makes This List Different
Every "best RTP slots" list on the internet is padded with titles that only hit 97%+ in bonus-buy mode. This list only counts the standard base RTP as available to regular players — no "Select Bonus" inflated figures.
Note: RTPs listed are theoretical figures published by providers. Actual casino-configured RTP may vary by operator. Always check the in-game paytable for the RTP at your specific casino.
The Top 20 — Ranked by RTP
1. 1429 Uncharted Seas — 98.60%
Thunderkick | Low volatility
The undisputed king of RTP. This Norse-mythology title looks dated by today's standards but delivers an exceptional 98.6% return. Low volatility means it drips wins consistently — perfect for low-budget, long sessions.
2. Blood Suckers — 98.00%
NetEnt | Medium volatility
NetEnt's classic vampire slot. Solid vampire-hunting bonus round adds a nice variance spike. The 98% figure is certified for standard play. This and 1429 Uncharted Seas are the best choices when a casino offers both.
3. Koi Gate — 96.19% / 98.10%
Habanero | Low volatility
Koi Gate operates at two published RTPs (96.19% standard, 98.10% in some markets). Check your casino's help page — if you're in a 98.10% region, this is a top-3 pick.
4. White Rabbit Megaways — 97.72%
Big Time Gaming | High volatility
Combines Megaways' enormous win potential with one of the highest RTPs in the high-volatility category. The Deep Below feature expands the reel row to 7 and unlocks huge multipliers. Outstanding value for a high-variance game.
5. Medusa Megaways — 97.63%
NextGen / SG Digital | High volatility
Medusa's stone-turning gaze also turns in an excellent 97.63% RTP. Megaways engine, cascading wins, and the Mega Multiplier Respin make this a hidden gem.
6. Immortal Romance — 96.86%
Microgaming | Medium volatility
A perennial favourite. The four-character storyline adds long-term engagement, and 96.86% is respectable for a title this popular. Wild Desire random feature can deliver enormous multi-line wins.
7. Thunderstruck II — 96.65%
Microgaming | Medium volatility
One of Microgaming's best-engineered slots. Four progressive features unlock as you collect feature triggers, making the long-term progression feel rewarding. Solid evergreen choice.
8. Big Bad Wolf — 97.34%
Quickspin | Medium-High volatility
Quickspin's flagship. Moonlight multiplier feature applies 2× during the first full moon, 3× during second, with expanding wilds. 97.34% is exceptional for a feature-rich title.
9. Esqueleto Explosivo 2 — 96.60%
Thunderkick | High volatility
Day-of-the-Dead theme with cascading wins and the Explosivo Wild (which removes surrounding symbols). A step up from the original, with better multiplier scaling.
10. Avalon II — 97.11%
Microgaming | Medium volatility
Grail Quest bonus has eight distinct features, making this one of the most content-rich slots ever built. 97.11% RTP justifies its continued presence at major casinos.
11. Starmania — 97.87%
NextGen / SG Digital | Low volatility
An underrated gem. Galaxy theme, 10 paylines, and a near-97.87% RTP make this the best option for players who want simple gameplay and excellent return.
12. Devil's Delight — 97.60%
NetEnt | High volatility
Criminally underplayed. Soul-collecting bonus meter fills across a session and unlocks escalating free spin rounds. 97.60% is exceptional for a high-variance pick.
13. Jackpot 6000 — 98.86% (non-supermeter)
NetEnt | Low volatility
Technically the highest RTP on this list, but only when you decline the Supermeter mode. Activate Supermeter and RTP drops to 74%. Play classic mode exclusively and this is the best-paying slot in existence.
14. Simsalabim — 97.50%
NetEnt | Medium volatility
Stage-magic theme with bonus chests revealing free spins, wilds, and multipliers. 97.50% makes it a solid pick at any casino that still carries it.
15. Kings of Chicago — 97.80%
NetEnt | Medium volatility
Poker-slot hybrid where winning hands trigger payouts instead of standard paylines. A genuinely unique mechanic combined with near-98% RTP.
16. Jokerizer — 98.00%
Yggdrasil | Low volatility
Yggdrasil's retro-styled Jokerizer hits 98.00% RTP in regular mode. Jokerizer mode drops it to 96.00%, so play the base mode only if you prioritise long return.
17. Blood Suckers II — 96.94%
NetEnt | Medium volatility
The sequel builds on the original. New Wild Hunt and Subterranean Treasures features add more variance. A touch below the original's 98% but still excellent.
18. Wish Upon a Jackpot — 97.20%
Blueprint Gaming | Medium volatility
Fairy-tale theme with a strong 97.20% base RTP. Blueprint's standard of locked reels and bonus trail make it a light, fun choice for the figures.
19. Ugga Bugga — 99.07%
Playtech | Low volatility
Tribal theme, and the highest published base RTP of any online slot at 99.07%. Critically, it's very hard to find at modern casinos. If your casino has it — play it.
20. Extra Chilli Megaways — 96.77%
Big Time Gaming | Very High volatility
BTG's answer to Bonanza with chilli pepper wilds and the bonus buy option. 96.77% is strong for a very-high-variance Megaways title. Best played in small doses.
