A Tetrimino is a type of four-pieced block found in the Tetris series of games. There are seven different types of Tetriminos across all titles, usually bearing the same coloring. They are integral to the gameplay of virtually almost every Tetris series game, and the success of the Tetris series has made the various Tetrimino blocks often referenced icons in the video game industry.
Crossover appearances in the Mario series can be observed in titles such as the original Game Boy release of Tetris, Tetris DS and Tetris & Dr. Mario. They appear as stickers in Super Smash Bros. Ultimate. In addition, Tetriminos make an appearance in Volume 10 of Super Mario-kun.
- Despite being named Tetris Attack, the gameplay of the game is not like any other Tetris game, and does not feature Tetriminos.
