Metamorphosis is an abstract strategy game played on a square board that was invented by Gregory Keith Van Patten in 2009. This game is a unique combination of a connection game and the Reversi-style piece flipping. Board initially setup like checkerboard pattern of white and black. Two players flip one piece at a turn trying to form a chain of pieces of their colors connecting the opposite edges of the board of the same color. On each turn players must decrease the number of groups on the board.
