Gravitrix

What it is

Gravitrix is a block-stacking game that @FranciscoHPro made for Vibe Jam 2026. On the jam page the author calls it "QWOP meets Tetris," a chaotic, physics-based multiplayer stacking game where blocks wobble and slide once they land. The home screen offers a Classic Mode and multiplayer. What sets it apart is that the blocks don't snap into a grid, so whether your stack holds depends on the physics. The jam rules require at least 90% of the code to be written by AI; the jam page doesn't list which AI tools were used.

Who it's for: Tetris fans who don't mind a bit of physics-driven chaos.

Before you start: under Vibe Jam's rules it's free to play in the browser with no sign-up. The pages are in English, and mobile support isn't stated. Multiplayer goes online. It's an independent game with no connection to the owners of Tetris or QWOP. No age rating is given.
