How to play Fusion Fever (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.
Fusion Fever is played on a 5×4 grid with 20 paylines.
- Set your stake. Choose your total bet per spin between $0.10 and $3,000. 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.

How winnings work (members only)
What 96.12% RTP costs per $100 wagered
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 96.12% RTP means
Expected return = stake × 96.12%
Over $100 of total bets, the long-run average loss is $3.88
RTP is a long-run average across millions of spins. Any single session can finish far above or below it, especially on a high volatility game.
Features explained (members only)
6 features explained: hold and win, fixed jackpots, free spins, multipliers and more
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.
Fixed jackpots
Jackpot prizes set at fixed multiples of your stake, such as Mini, Minor, Major and Grand.
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.
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.
Respins
Selected reels or the whole grid spin again without a new stake, usually triggered by a specific symbol combination or near-miss feature.
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. High volatility concentrates the return in rare, large wins. Long losing runs are normal. Keep stakes small (around 1% of your session budget or less) so you can ride out the swings. A simple rule: bring at least 300 spins' worth of budget, so a $50 budget suggests a stake of about $0.17.
3 more tips and a session planner
- Check which RTP version you're playing. Fantasma Games offers this game at 96.12%, 94.12%, 92.12%. Open the game rules at your casino and prefer sites running the 96.12% version.
- Bonus wagering: at 96.12% RTP, clearing $1,000 of wagering costs about $38.80 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.
