Over the years, the Tetrominoes have underwent a countless amount of revisions. Some Tetris games even have variants depending on the mode you're playing. Rarely, there are also additional colors in certain variants of Tetris that you usually wouldn't see in regular gameplay. In certain Tetris variants, Tetrominoes have a dedicated sprite when the blocks land on the playfield. Plus, additional block sprites like item sprites will also be featured.
