Set your stake. Choose your total bet per spin between $0.10 and $100. Wins are paid as multiples of this stake.

What 94.5% RTP costs per $100 wagered

What 94.5% RTP means

Expected return = stake × 94.5%
Over $100 of total bets, the long-run average loss is $5.50

RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a volatile game.

Features explained (members only)

4 features explained: free spins, hold and win, bonus wheel, fixed jackpots

Free spins

A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.

Hold and win

Landing enough special cash or coin symbols starts a respin feature: those symbols lock in place, the respin counter resets each time a new one lands, and their values are collected when the feature ends.

Bonus wheel

A wheel feature that awards a prize, multiplier, jackpot or entry into another bonus round.

Fixed jackpots

Jackpot prizes set at fixed multiples of your stake, such as Mini, Minor, Major and Grand.
