Fusion Fever

Fusion Fever from Fantasma Games is set in Professor Fusion's underground laboratory, a place of pipes, glowing machinery, radioactive gear and cartoon mice. The game has five reels, four rows and 20 fixed paylines, and bets range from 0.10 to 3,000. Release is planned for 24 November 2026.

Volatility is high. The default RTP is 96.12%, and lower versions at 94.12% and 92.12% exist too. No top prize is listed for this one.

Everything revolves around Energy symbols, which carry values from 0.2x to 10x the bet. What happens depends on how many appear together in a spin. Between one and three give a random chance of setting off the Fever Wheel, whose cash prize runs from 10x to 500x. Exactly four guarantee a random win multiplier of x2, x3, x4, x5 or x10 on that spin. A count of five or more starts the Fusion Bonus.

That bonus starts with three spins, and the Energy symbols that caused it stay locked in place. Every new Fusion symbol is given the total value of those triggering Energy symbols, so a strong opening set makes each later Fusion symbol worth more. Fresh Fusion, Multiplier and Fever symbols all lock and put the spin counter back at three. Multiplier symbols lift the Energy and Fusion values already on the grid, and filling every position earns a turn on the Fever Wheel. When spins run out, all the Energy, Fusion and Fever prizes are summed and paid.

A second feature route is the Bonus Spins round: Bonus symbols on the middle three reels, 2, 3 and 4, award 15 spins. An Energy Collector stays live during the whole round and gathers the combined value of one to four Energy symbols each time they show. Should five or more Energy symbols land inside the round, the Fusion Bonus starts from within it, giving a second entry to the same collection mechanic.

Features feed each other here: Energy count decides which extra fires, Fusion symbols inherit value, and the free spins can nest the main bonus inside themselves. That structure suits a player who likes a game where one symbol type controls several outcomes.
