How winnings work (members only)
What 95.4% RTP costs per $100 wagered, the 4,000x max win at a $1 stake
The top prize is capped at 4,000x your stake. On a $1 spin that is $4,000; on $0.20 it is $800. 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 95.4% RTP means
Expected return = stake × 95.4%
Over $100 of total bets, the long-run average loss is $4.60
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)
8 features explained: bonus buy, expanding wilds, respins, free spins and more
Bonus buy
Lets you pay a fixed multiple of your stake to enter the bonus feature straight away instead of waiting for it to trigger. It raises variance considerably and is not available in every country (it is banned in the UK).
Expanding wilds
When an expanding wild lands, it grows to cover its whole reel, turning one symbol into a full column of wilds.
Respins
Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.
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.
Sticky wilds
Sticky wilds stay locked in place for several spins or for the rest of a feature, giving every following spin a better chance of connecting wins.
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.
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.
3 more tips and a session planner
- Treat bonus buys as high-risk. Buying the feature concentrates your budget into a few large-variance rounds. Many results return less than the price paid. Read our bonus buy guide first.
- Bonus wagering: at 95.4% RTP, clearing $1,000 of wagering costs about $46.00 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.
