Tetriszen

Tetriszen is a single player, freeware, Tetris clone. It is entirely keyboard controlled and plays just like every other game of this type in that blocks of varying shape fall from the top of the screen and the player must use them to construct a solid line of blocks horizontally. Horizontal rows score points then disappear allowing other blocks to fall down.

The object is to achieve a high score and the game continues until the game screen fills up with the blocks falling faster and faster the longer the game continues.
