Blokus - Rules of Play says:
Blokus (officially pronounced "Block us") is an abstract strategy game with transparent, Tetris-shaped, coloured pieces that players are trying to play onto the board. The only caveat to placing a piece is that it may not lie adjacent to your other pieces, but instead must be placed touching at least one corner of your pieces already on the board.
