Unlace

Unlace is a blocking game (a game of fighting for room to move) derived from Squish. Starting with the same layout as in Squish, players take turns moving one of their friendly pieces to an adjacent space. However, the moved piece must belong to a larger group than the one before the move. The player who fails to move during their turn loses. This game is included in Generic Board "Hexagonal" set. —description from the designer
