How to play Diamond Duke (members only)
Wins are paid when matching symbols land on an active payline, usually left to right starting from the leftmost reel. Your total stake is spread across the lines, and each line win is the line bet multiplied by the symbol's paytable value.

- Set your stake. Choose your total bet per spin between $0.05 and $100. Wins are paid as multiples of this stake.
- Check the paytable. Open the game's info screen to see what each symbol pays and the exact rules for this version.

How winnings work (members only)
What 96.23% RTP costs per $100 wagered, the 8,000x max win at a $1 stake
The top prize is capped at 8,000x your stake. On a $1 spin that is $8,000; on $0.20 it is $1,600. 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 96.23% RTP means
Expected return = stake × 96.23%
Over $100 of total bets, the long-run average loss is $3.77
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)
4 features explained: multipliers, pick bonus, bonus wheel, symbol upgrades
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.
Pick bonus
A bonus game where you choose from hidden items to reveal cash prizes, multipliers or extra features.
Bonus wheel
A wheel feature that awards a prize, multiplier, jackpot or entry into another bonus round.
Symbol upgrades
Lower-paying symbols are transformed into higher-paying ones during a feature.
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.
2 more tips and a session planner
- Bonus wagering: at 96.23% RTP, clearing $1,000 of wagering costs about $37.70 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.
