Bastet ("bastard tetris") is an ncurses Tetris clone which is harder than every other tetris released. It is based on a heuristics engine which tries to detect which block you need or don't need, and then gives you the blocks that you don't need.

The heuristics have been worked on for some time and are quite nasty.
