Gardner proposed several simple games with a set of free pentominoes and a chessboard. Some variants of the Sudoku puzzle use nonomino-shaped regions on the grid. The video game Tetris is based on the seven one-sided tetrominoes (spelled "Tetriminos" in the game), and the board game Blokus uses all of the free polyominoes up to pentominoes.

Tetris (Russian: Тетрис [a]) is a puzzle video game created in 1985 by Alexey Pajitnov, a Soviet software engineer. In Tetris, players complete lines by moving tetrominoes, which descend onto the playing field. The completed lines disappear and grant the player points, and the player can proceed to fill the vacated spaces.
Tetris was inspired by pentomino puzzles, although it uses four-block tetrominoes. Some Tetris clones and variants, like the game 5s included with Plan 9 from Bell Labs, and Magical Tetris Challenge, do use pentominoes. Daedalian Opus uses pentomino puzzles throughout the game.
