Hexahedral

How to play Hexahedral?

Hexahedral is a minimalist push puzzle played on a colored grid. Each tile starts raised, and your job is to press every block down flat in as few moves as possible — but pushing one cube nudges its neighbors, so the grid reacts like a chain. Solving a board means finding the exact order of presses that settles everything at once instead of popping pieces back up. There are 30 hand-built levels with smooth CSS animation, and the difficulty climbs steadily as the grids grow and the ripple effects get harder to predict.

• Push a block — Click or tap any cube on the grid
• Undo — Undo button to step back a move
• Restart level — Reset button to reset the grid
• Fullscreen — Press F or click the expand icon

Work from the corners inward. Corner and edge tiles have fewer neighbors, so pressing them first gives you the most predictable ripples.

Think of each press as a switch that also flips its neighbors — solving the board is about parity, not brute force.

If a level resists, restart and try a different starting cube. The minimum-move solution often hinges on which tile you touch first.
