How winnings work (members only)
What 96.1% RTP costs per $100 wagered, the 10,000x max win at a $1 stake
The top prize is capped at 10,000x your stake. On a $1 spin that is $10,000; on $0.20 it is $2,000. When the cap is reached the round usually ends immediately.
Because winning symbols tumble away and are replaced, one paid spin can produce a chain of wins. All of them count towards that spin's total.
What 96.1% RTP means
Expected return = stake × 96.1%
Over $100 of total bets, the long-run average loss is $3.90
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a low volatility game.
The published hit frequency is 24.5%, meaning roughly one spin in 4.1 returns something — though many of those wins are smaller than the stake.
Features explained (members only)
6 features explained: tumbling reels, bonus buy, hold and win, respins and more
Tumbling reels
After a win, the winning symbols are removed and new ones fall into their place. This can create several consecutive wins from a single paid spin. Also called cascades or avalanches.
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).
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.
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.
Wild symbols
Wilds substitute for regular paying symbols to help complete winning combinations. They do not normally replace scatter or bonus symbols.
Strategy tips (members only)
- Size your stake to the volatility. Low volatility means frequent, smaller wins and a smoother balance. It suits longer sessions and bonus wagering, but big multipliers are rare. A simple rule: bring at least 100 spins' worth of budget, so a $50 budget suggests a stake of about $0.50.
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 96.1% RTP, clearing $1,000 of wagering costs about $39.00 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.
