Tetromino


Tetrominoes

A tetromino is a 4-polyomino. There are five free tetrominoes, seven one-sided tetrominoes, and 19 fixed tetrominoes. The free tetrominoes are known as the T-tetromino, L-tetromino, skew tetromino, square tetromino, and straight tetromino, respectively.

The shapes were popularized in the game Tetris, developed by Alexey Pajitnov in June 1985.
