About
Tetris: the seven tetromino shapes fall, you slide and spin them to pack full rows, and full rows clear for points. It speeds up in your head long before it speeds up on screen.
How it works
A 10×20 grid; each piece is a small matrix rotated by transpose-and-reverse, with collision checks against the walls and settled blocks. Cleared rows score 40/100/300/1200 for 1–4 lines. Best score in localStorage under kaspirius:tetris:best. No backend.
