Hextris

Logan Engstrom built Hextris as a Ludum Dare entry and open-sourced it immediately. The elevator pitch writes itself: Tetris, but the blocks fall inward toward a rotating hexagon instead of downward into a well. Match three or more of the same color to clear them. Chain multiple clears to build a score multiplier.

The rotation mechanic is what separates it from the inspiration. In Tetris, the board is static and you move the piece. In Hextris, you rotate the entire hexagon left or right to position the falling block where you want it to land. This inversion changes the feel completely. You are not stacking pieces. You are spinning a target to meet them.

Chains are the scoring engine. Clear blocks, and if the removal causes new blocks to match, those clear too. A four-chain clear in the first thirty seconds will give you a score that takes ten minutes of steady play to match without chains. The game rewards patience followed by deliberate execution.

The hexagon gets busier as the game goes on. Blocks fall faster. The safe windows between pieces shrink. The decision-making timeline compresses until you are reacting to blocks that are already almost at the hex before you have registered their color.

Why it’s on the guide: MIT, open source, genuinely novel mechanic built on familiar bones. One of the better Ludum Dare games to make it to a permanent home.
