ONEXENO is a edge-matching card game with 70 unique cards (per deck) representing the complete set of TriHadamard kernels. The basic game may be played by 2 to 7 players, ages 7 and up. Players make points by arranging rows of edge-matching cards. When a row of five cards is complete, the player takes the points indicated on the face of the card. This simple rule leads to exceptional complexity and engaging strategic play.
