About Gravitrix

Gravitrix is a stacking game where the blocks refuse to sit still. You build structures from Tetris-style pieces, but the handling is awkward and physics-driven in the manner of QWOP, so every block you place can wobble, slide or topple while the simulation pushes back.

It sets two familiar ideas against each other: the tidy planning of a stacking puzzle and the unpredictable behavior of physical objects. You stack against other players online, and having them in the match adds to the chaos. It is a casual puzzle game that runs on Three.js in desktop and phone browsers.

The creator describes recently starting to make the games they had long wanted to make. This one, put together with Claude Code, came 216th of the 945 Vibe Jam 2026 entries.
