Tetris Pro is a fairly straightforward Tetris variant by a Dutch demo group. It features high-resolution graphics, modtracker music and the option to switch between different sets of background image themes (although only one such set, or "data disk", was provided by the developers). The game plays by standard rules, and the player progresses through levels by accumulating a certain amount of points. However, it is possible to increase the challenge by starting the game with up to seven rows at the bottom randomly filled with incomplete lines of blocks.
