How winnings work (members only)

What 89% RTP costs per $100 wagered, the 3,750x max win at a $1 stake

The top prize is capped at 3,750x your stake. On a $1 spin that is $3,750; on $0.20 it is $750. 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 89% RTP means

Expected return = stake × 89%
Over $100 of total bets, the long-run average loss is $11.00

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: bonus wheel, wild symbols, multipliers, progressive jackpot

Bonus wheel

A wheel feature that awards a prize, multiplier, jackpot or entry into another bonus round.

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.

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. 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

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 89% RTP, clearing $1,000 of wagering costs about $110.00 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.
