How winnings work (members only)
What 96.25% RTP costs per $100 wagered
What 96.25% RTP means
Expected return = stake × 96.25%

Features explained (members only)
6 features explained: free spins, walking wilds, wild symbols, respins 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.
Walking wilds
Walking wilds move one position (usually one reel to the left) after each spin and trigger a respin, until they walk off the grid.
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
Respins
Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.
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).
Progressive jackpot
A jackpot that grows with a share of every qualifying bet until someone wins it. Contributions are funded from the game's RTP.
Strategy tips (members only)
- Size your stake to the volatility. Very high volatility means most spins lose and a large share of the return comes from rare big features. Treat it as entertainment with a strict budget and a stake of around 0.5% of your session budget or less. A simple rule: bring at least 400 spins' worth of budget, so a $50 budget suggests a stake of about $0.12.
4 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.
- Check jackpot eligibility. Some progressive jackpots require a minimum or maximum stake to win the top prize. Part of every bet funds the jackpot, so base-game RTP is lower.
- Bonus wagering: at 96.25% RTP, clearing $1,000 of wagering costs about $37.50 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.
