How winnings work (members only)

What 93.7% RTP costs per $100 wagered

What 93.7% RTP means

Expected return = stake × 93.7%
Over $100 of total bets, the long-run average loss is $6.30

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

Features explained (members only)

5 features explained: free spins, wild symbols, hold and win, bonus buy and more

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.

Wild symbols

Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.

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 buy

Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).

Fixed jackpots

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

Strategy tips (members only)

Size your stake to the volatility. Medium volatility balances hit rate and win size. Expect dry spells between features, but not extreme swings. A simple rule: bring at least 200 spins' worth of budget, so a $50 budget suggests a stake of about $0.25.

3 more tips and a session planner

Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
Bonus wagering: at 93.7% RTP, clearing $1,000 of wagering costs about $63.00 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
Set limits before you spin. Decide your loss limit and session time in advance and stop when you reach either. No pattern or betting system changes the outcome of a spin.
