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.
