Reaktor

Reaktor is a block-stacking game where you build stacks in four dimensions rather than on a flat board. You create chains and combos to trigger large clears, and can compete solo or play with others.

Stack and react

Advanced techniques include X-ray, zipper and zig-zag setups. Build combos to clear blocks and chase high scores on the global leaderboards.
