About this game

Stack 3D tetrominoes on floating platforms and fill whole layers to clear them.

3D Tetris was created primarily with AI coding tools (Lovable), the fast-growing “vibe coding” approach where AI agents write most of a game’s code. It’s part of our curated collection of free AI puzzle, word & trivia games — every listing is checked by hand before it appears here.

What are AI browser games?

AI browser games are playable games whose code was written mostly by AI coding agents — Claude Code, Cursor, Codex, GPT, Grok and others — instead of being hand-coded over months. A single developer (or a small team) directs the AI with prompts, tests the result and ships; whole games now come out of weekend game jams like Vibe Jam and the AI Browser Game Jam. BrowserAI Games curates the best of them so you can find and play them in one place.
