How winnings work (members only)
What 96.1% RTP costs per $100 wagered, the 1,616x max win at a $1 stake
The top prize is capped at 1,616x your stake. On a $1 spin that is $1,616; on $0.20 it is $323.20. 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 96.1% RTP means
Expected return = stake × 96.1%
Over $100 of total bets, the long-run average loss is $3.90
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a low volatility game.
Features explained (members only)
3 features explained: wild symbols, multipliers, mystery symbols
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
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.
Mystery symbols
Special symbols that all reveal the same randomly chosen regular symbol, which can complete several wins at once.
Strategy tips (members only)
- Size your stake to the volatility. Low volatility means frequent, smaller wins and a smoother balance. It suits longer sessions and bonus wagering, but big multipliers are rare. A simple rule: bring at least 100 spins' worth of budget, so a $50 budget suggests a stake of about $0.50.
2 more tips and a session planner
- Bonus wagering: at 96.1% RTP, clearing $1,000 of wagering costs about $39.00 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.
