Start from your corner and try to put all your pieces, one after one, on the board.
Each piece must touch another one of the same color through a corner, never by a side.
But don't let the artificial intelligence put its pieces !

That may seem simple. And in fact it's really so simple that you'll begin to play immediatly. But you'll discover how interesting it gets and you'll understand why the Blokus board game was nominated for the famous Game of the year award, after having successively won the Golden Lock, Grand Prix du Jouet and Super Golden Ace prizes!
