Papagra (2006)

Papagra is a perfect-information abstract strategy game for two, played with Go stones or glass beads on a hexagonal grid. In the game, opponents try to form what are called "matched groups". A matched group is a group of connected pieces, the size and shape (but not necessarily orientation) of which match the size and shape of a connected, enclosed group of empty spaces somewhere on the board. The player who forms the largest matched group during the course of the game is the winner. Papagra is a brain burner that rewards strong pattern recognition and visuo-spatial skills.
