A Tetris clone for the ColecoVision. Despite being an early home-brew, Kevtris features both colourful graphics and background music, as well as three different game modes for both one and two players as well as handicaps. Apart from the normal Tetris game mode, there is the zero-out mode, where you have to clear a set number of lines to win a game, and the builder mode, where the blocks don't fall automatically, giving you all the time in the world to plan your moves.
