How to Play

Xor is short for “exclusive or”. It's a mathematical operation for ones and zeros. But rest assured, to play this game no math skills are needed. There are several ways to recognize a group. Counting dots, using binary arithmetics, or our personal favorite, spatial thinking.

Assume two dots of the same color cancel each other. Look for groups of cards where all dots get canceled.

Most players discover their personal strategy after a few rounds of play. What will be yours?
