UNAUTHORIZED PRODUCTION The information that BGG has on this item indicates that The Strategy Game is a non-authorized version of Blokus Duo. In this two-player game, players place geometric figures onto the board, but must place such that their new piece touches at least one of their previous pieces, but at corners only. The player who gets the most of his or her pieces placed by the end of the game is the winner. Though named the same, this is not identical to The Strategy Game, a similar unauthorized replica but of Blokus i.e. for four players.
