Blockout is a Tetris variant with an added twist: it's in 3D. The player can rotate the blocks in 3D in order to fit them into the pit they are being guided into. Advanced users can play this game with odd three-dimensional pieces, or change the size of the pit, for depth of between 6 and 18 piles, and width and length of between 3 and 7.

The graphics from the game are stored directly in .LBM files (a format supported by Deluxe Paint), thus can be modified directly.

Tetris variant

Unlike Welltris (which billed itself as Tetris in three dimensions), Blockout was the first true 3D Tetris variant.
