How to play Mice Heist (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.
Mice Heist is played on a 5×3 grid with 10 paylines.
- Set your stake. Choose your total bet per spin between $0.10 and $45. 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.
- Trigger the bonus. Land the required scatter symbols to start the free spins feature.
- Optional ante bet. Pay extra per spin to raise the chance of triggering the feature.

How winnings work (members only)
What 94.5% RTP costs per $100 wagered, the 2,500x max win at a $1 stake
The top prize is capped at 2,500x your stake. On a $1 spin that is $2,500; on $0.20 it is $500. 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 94.5% RTP means
Expected return = stake × 94.5%
Over $100 of total bets, the long-run average loss is $5.50
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a medium volatility game.
Features explained (members only)
4 features explained: free spins, hold and win, multipliers, ante bet
Free spins
A bonus round of spins played at no cost to your balance, usually triggered by landing three or more scatter symbols. Wins during the round are added to your balance, and many games let you retrigger extra spins.
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.
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.
Ante bet
An optional extra charge on each spin, typically +25%, that increases the chance of triggering the bonus feature.
Strategy tips (members only)
- Size your stake to the volatility. Medium volatility balances hit rate and win size. Expect dry spells between features, but not extreme swings. A simple rule: bring at least 200 spins' worth of budget, so a $50 budget suggests a stake of about $0.25.
4 more tips and a session planner
- Check which RTP version you're playing. Inspired Entertainment offers this game at 94.5%, 93%, 92%. Open the game rules at your casino and prefer sites running the 94.5% version.
- 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 94.5% RTP, clearing $1,000 of wagering costs about $55.00 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.
