Which online casinos have the highest RTP for slot machines?

See if the site lists eCOGRA or iTech Labs audits of the games -- this will ensure honest RTP figures. Many reputable online casinos now list individual game RTPs. You can also filter by "Game Provider"; NetEnt slots such as Starburst often have better payback percentages than others.

To test for provable fairness, look for blockchain-powered RNGs – if the casino is provably fair, you can run the calculations post-game and verify that the results are accurate. You may even see a display of the “hash logs” listed on the same page where you make your bets.

Leading operators such as 888 Casino, LeoVegas, and Bet365 all publish actual real-life RTP figures for their games. You can also look for each slot game’s RTP here (Play’n GO) and here (Microgaming). Do not rely on the casino operator’s word alone: Verify independently via game certification websites or directly with the slot developer. Slots are games of luck and chance, and the house always wins over time, no matter how high a game’s RTP is.

Here are some reputable high RTP slots casinos with RTP’s above 96 percent, sometimes as high as 98 percent: NetBet, Leo Vegas, and Mr Green. There are also provably fair casino sites like Bitsler or Edgeless, which allow you to test every individual outcome. Check the RTP of the slot game in question under the help section. Gamble responsibly!

Instead, choose a casino regulated by the UKGC or MGA, which requires operators to publicize their RTP data. Look at sites such as SlotsRank or CasinoSmash for the latest information, and remember that Book of Dead (96.54%) and Gonzo’s Quest (96.06%) are reliable choices. You might also want to find out if the casino uses provably fair technology (such as NProv or Bitcoin). You can even check the underlying random-number-generator code in some peer-to-peer casinos. But always compare the listed RTP number online with what is displayed on the actual game page – they don’t always match.
