Like minimalist games? Then you won't do much better than Binary Tetris, a reworking of Tetris into dots and pound signs. GitHub user Aemkei, who has previously translated Conway's Game of Life and a 3D "library" into code of 140 characters, has recreated Tetris in enough JavaScript to fill a tweet. The game's blocks come only in one shape, and there's no way to rotate them, but it's an interesting proof of concept that can be played here. There's also no scoring system, so we amateur players can get a break from the competitive Tetris masters in our midst. For fully annotated code, click through to the source link below.
