How winnings work (members only)
What 98% RTP costs per $100 wagered, the 72,694x max win at a $1 stake
The top prize is capped at 72,694x your stake. On a $1 spin that is $72,694; on $0.20 it is $14,538.80. 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 98% RTP means
Expected return = stake × 98%
Over $100 of total bets, the long-run average loss is $2.00
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a very high volatility game.
Features explained (members only)
5 features explained: free spins, wild symbols, multipliers, sticky 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.
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.
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.
Expanding wilds
When an expanding wild lands, it grows to cover its whole reel, turning one symbol into a full column of wilds.
Strategy tips (members only)
- Size your stake to the volatility. Very high volatility means most spins lose and a large share of the return comes from rare big features. Treat it as entertainment with a strict budget and a stake of around 0.5% of your session budget or less. A simple rule: bring at least 400 spins' worth of budget, so a $50 budget suggests a stake of about $0.12.
3 more tips and a session planner
- Check which RTP version you're playing. Habanero offers this game at 98%, 97%, 94%, 92%, 86%. Open the game rules at your casino and prefer sites running the 98% version.
- Bonus wagering: at 98% RTP, clearing $1,000 of wagering costs about $20.00 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.
