How winnings work (members only)
What 96.15% RTP costs per $100 wagered, the 5,000x max win at a $1 stake
The top prize is capped at 5,000x your stake. On a $1 spin that is $5,000; on $0.20 it is $1,000. When the cap is reached the round usually ends immediately.
What 96.15% RTP means
Expected return = stake × 96.15%
Over $100 of total bets, the long-run average loss is $3.85
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: hold and win, bonus buy, ante bet, gamble feature and more
Hold and win
Landing enough special cash or coin symbols starts a respin feature: those symbols lock in place, the respin counter resets each time a new one lands, and their values are collected when the feature ends.
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).
Ante bet
An optional extra charge on each spin, typically +25%, that increases the chance of triggering the bonus 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.
Fixed jackpots
Jackpot prizes set at fixed multiples of your stake, such as Mini, Minor, Major and Grand.
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.
4 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.
- Understand the ante bet. It costs more per spin to trigger features more often; it does not change the game into a better bet.
- Bonus wagering: at 96.15% RTP, clearing $1,000 of wagering costs about $38.50 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.
