How winnings work (members only)
What 94.15% RTP costs per $100 wagered, the 10,000x max win at a $1 stake
The top prize is capped at 10,000x your stake. On a $1 spin that is $10,000; on $0.20 it is $2,000. When the cap is reached the round usually ends immediately.
Because wins don't depend on lines, every symbol in view can count towards a pay. The paytable lists how many matching symbols each tier needs.
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 94.15% RTP means
Expected return = stake × 94.15%
Over $100 of total bets, the long-run average loss is $5.85
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a high volatility game.
Features explained (members only)
4 features explained: cluster pays, multipliers, wild symbols, free spins
Cluster pays
Wins are formed by groups of matching symbols touching horizontally or vertically, rather than along lines.
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.
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
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.
Strategy tips (members only)
- Size your stake to the volatility. High volatility concentrates the return in rare, large wins. Long losing runs are normal. Keep stakes small (around 1% of your session budget or less) so you can ride out the swings. A simple rule: bring at least 300 spins' worth of budget, so a $50 budget suggests a stake of about $0.17.
2 more tips and a session planner
- Bonus wagering: at 94.15% RTP, clearing $1,000 of wagering costs about $58.50 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.
