How winnings work (members only)
What 96.53% RTP costs per $100 wagered, the 25,000x max win at a $1 stake
The top prize is capped at 25,000x your stake. On a $1 spin that is $25,000; on $0.20 it is $5,000. 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 96.53% RTP means
Expected return = stake × 96.53%
Over $100 of total bets, the long-run average loss is $3.47
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a volatile game.
The published hit frequency is 14.8%, meaning roughly one spin in 6.8 returns something — though many of those wins are smaller than the stake.
Features explained (members only)
7 features explained: free spins, multipliers, wild symbols, expanding wilds 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.
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.
Expanding wilds
When an expanding wild lands, it grows to cover its whole reel, turning one symbol into a full column of wilds.
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.
Respins
Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.
Gamble feature
After a win you can risk it on a double-or-nothing guess, such as the colour of a card. It does not improve the game's long-term return.
Strategy tips (members only)
- Bonus wagering: at 96.53% RTP, clearing $1,000 of wagering costs about $34.70 on average. Check the bonus terms, as some casinos exclude specific games. Run your numbers in the wagering calculator.
1 more tip
- 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.
