Cube Clasher is a turn-based block puzzle battle. You and the AI share one 8×8 board — place your blocks, fill rows or columns to clear them, and outscore your opponent before the board runs out of space.

A living AI opponent

This is not a static puzzle bot. The AI reads the battle and switches personality as the score swings: falling behind, it turns greedy and chases every line; ahead of you, it becomes a ruthless blocker; board almost full, it fights for survival. Every match plays out differently because your opponent adapts to you.

Simple to play, hard to master

Drag blocks onto the board; fill a row or column to clear it and score. Tap a block to rotate it (rotations are limited — spend them wisely). Clear multiple lines at once for combo multipliers. When no block fits, the battle ends — highest score wins.
