Quantum Reactor gameplay: a 6×5 grid of reactor symbols with the spin button and bet panel.

About the game

Quantum Reactor is set inside an unstable research reactor. Three or more matching symbols that touch form a cluster, which pays and is removed. New symbols fall from above, and each further cascade moves one step up the multiplier ladder. A spin can run up to ten cascades.

Wilds do not substitute for other symbols. Each carries a multiplier that grows by +1 on every cascade from the second one. In the base game the sum of wild multipliers multiplies the spin win. In free spins it is added to a bonus multiplier that stays until the bonus ends.

Features

Cascades and multiplier ladder
Winning clusters pay and are removed, then the grid refills. Cascade n pays at step n of the ladder: ×1 to ×10 in the base game, ×1 to ×18 in free spins.
Resonance on refill
New symbols can repeat the symbol of the largest cluster just paid. The chance is 25% on the first cascade and rises to 55% from the fourth.
Multiplier wilds
A wild lands with a multiplier of ×2 or more and gains +1 on every cascade from the second one. The cap is ×500 per wild.
Unstable reactor
In the base game, after a winning cascade one of the remaining symbols can turn into a multiplier wild.
Free spins with a persistent multiplier
3, 4, 5 or 6+ scatters award 10, 15, 20 or 25 free spins. Wild multipliers are added to a bonus multiplier that lasts the whole bonus. Retriggers follow the same scale.
