A pentomino (also known as a pentimino) is a polyomino of five squares.
The ancient pentomino puzzle uses free pentominoes. It was the inspiration behind Tetris. Aleksey Pazhitnov found pentiminoes to be too complex, so he simplified it to tetriminoes.
Despite having a page on this wiki, most games do not have these.
Pentominos appear in Puyo Puyo Tetris as a party item.
