How winnings work (members only)
What 96% 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.
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% RTP means
Expected return = stake × 96%
Over $100 of total bets, the long-run average loss is $4.00
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a medium–high volatility game.

1 feature explained: tumbling reels
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.
Strategy tips (members only)
- Size your stake to the volatility. Medium-to-high volatility means longer gaps between meaningful wins, with most of the return concentrated in features. Use smaller stakes relative to your budget. A simple rule: bring at least 250 spins' worth of budget, so a $50 budget suggests a stake of about $0.20.
3 more tips and a session planner
- Check which RTP version you're playing. Relax Gaming offers this game at 96%, 94%. Open the game rules at your casino and prefer sites running the 96% version.
- Bonus wagering: at 96% RTP, clearing $1,000 of wagering costs about $40.00 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.
