Some games come with different RTP settings. Only casinos that hold current UKGC licences can legally accept bets from people living in the UK.

Gonzo’s Quest from NetEnt has earned legendary slot status in the industry. The game has a 96.82% RTP, which is a notch above the 96% average.

There are some bonus extras in the form of multiple free spin features, Scatter Wins, and Sticky Wilds. If you play just 1 coin per spin, the RTP drops to 76.9%.
Ugga Bugga, Steam Tower, and Sizzling Hot Deluxe have some of the highest RTPs, and you can play them at BetMGM, Betano, Kwiff, and Betfred. It means that for every £100 staked on that slot, you can expect, on average, £98. We also like that you don’t need downloads to play Steam Tower on the go at Betano. Clicking on either the icon or the help button reveals a description of the game, including its features, paylines, and RTP.
