How to play StarSpell (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.
StarSpell is played on a 5×3 grid with 10 paylines.
- Set your stake. Choose your total bet per spin between $0.10 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.
- Spin. Each spin's result is decided by a certified random number generator, independent of previous spins.

How winnings work (members only)
What 96.17% RTP costs per $100 wagered, the 1,200x max win at a $1 stake
The top prize is capped at 1,200x your stake. On a $1 spin that is $1,200; on $0.20 it is $240. 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 96.17% RTP means
Expected return = stake × 96.17%
Over $100 of total bets, the long-run average loss is $3.83
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.
Features explained (members only)
4 features explained: expanding wilds, sticky wilds, respins, multipliers
Expanding wilds
When an expanding wild lands, it grows to cover its whole reel, turning one symbol into a full column of wilds.
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.
Respins
Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.
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.
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.
2 more tips and a session planner
- Bonus wagering: at 96.17% RTP, clearing $1,000 of wagering costs about $38.30 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.
