Three in a row — in three dimensions.

Tic-tac-toe rebuilt as an isometric stacking duel. Drop glowing prisms into a 3×3 arena where they pile three high — any straight line of three wins, whether it runs flat, straight up, or diagonally through the cube. Face three CPU minds (Drift wanders, Pulse blocks and strikes, Prime sees four moves deep) and build a win streak for multiplied scores, or pass the device for a local two-player duel.
