Pentominoes

The pentomino is a geometric pattern which is the basis of a number of tiling patterns and puzzles. There is also a board game of skill based on it, called pentominoes.

The game is played on a 8x8 grid by two or three players. Players take turns in placing pentominoes on the board so that they do not overlap with existing tiles and no tile is used more than once. The objective is to be the last player to place a tile on the board.

The two-player version has been solved; it is a first-player win.
