How winnings work (members only)
What 95.66% RTP costs per $100 wagered, the 2,551x max win at a $1 stake
The top prize is capped at 2,551x your stake. On a $1 spin that is $2,551; on $0.20 it is $510.20. When the cap is reached the round usually ends immediately.
Multipliers are applied to wins as they land; in many games several multipliers add together or multiply each other, which is where the largest wins come from.
What 95.66% RTP means
Expected return = stake × 95.66%
Over $100 of total bets, the long-run average loss is $4.34
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)
4 features explained: multipliers, respins, mystery symbols, fixed jackpots
Multipliers
Multipliers increase a win by a set factor, such as 2x or 10x. They can be attached to symbols, applied to a whole spin, or grow during a feature, and are a main driver of the biggest wins.
Respins
Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.
Mystery symbols
Special symbols that all reveal the same randomly chosen regular symbol, which can complete several wins at once.
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.
2 more tips and a session planner
- Bonus wagering: at 95.66% RTP, clearing $1,000 of wagering costs about $43.40 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.
