The Cube: Chain Reaction

Make room for your next move in The Cube: Chain Reaction, a block puzzle with two ways to play.

Drag blocks onto an 8-by-8 board, complete rows and columns, and link your clears into combos. Choose the order of your three blocks carefully: one clear can open the space you need for the next shape.

ENDLESS
Build your score and keep the board open. Clear the whole board to continue on another themed map while keeping your run going. Set up special black hole clears to sweep away the remaining blocks, and see how far your planning takes you.

ADVENTURE
Work through 649 levels with gem-collection or score goals. Every completed level adds tiles to Monsoon Window, a mosaic of sea, mountains, leaves and sunlight. Follow the picture as it grows, one puzzle at a time.

COLORFUL BLOCKS, SATISFYING CLEARS
Explore varied tile materials and themed boards, with animated clears, sound effects and optional haptic feedback. Simple drag controls leave the challenge in choosing where each shape belongs.

KEEP YOUR PROGRESS
Your progress is saved on your device, so you can return to an unfinished game. Core puzzles can be played offline. No account is required, and there are no in-app purchases or subscriptions.

ADS AND OPTIONAL CHOICES
The game includes interstitial ads at selected breaks. When available, you can choose a rewarded ad to revive a failed run, up to twice per Endless run or Adventure attempt. Ads require an internet connection. Usage statistics and crash diagnostics are separate optional settings and are off by default.

Plan the space, clear the lines, and build your next chain reaction.
