Block Reactor
Block puzzle with chain reactions, combos and charms. Every line is a reaction!
Drag blocks, clear lines… and watch your score explode. Block Reactor is the block puzzle you know, now with chain reactions and Chips × Mult combos that keep growing.
EASY TO PLAY
- Drag pieces onto the 8×8 board and fill rows or columns to clear them.

BUILD YOUR COMBO

- Charms trigger from left to right, so their order matters.
- Boosts to reshuffle, rotate or add pieces when you need them.
