Game Manual Player GRYB Rules
GRYB® is a game for two and possibly more players. The object of the game is simple— get four tokens arranged so that they form a "GRYB." As you may have guessed GRYB stands for Green Red Yellow Blue, and the game is fascinating and challenging.  Winning moves called "GRYBs" can be of differing degrees of complexity, and are worth from 1 to 15 points.   GRYB is one of the most mentally-stimulating games you could ever wear on your head.
