3=0

3=0 is a fast-paced card-matching puzzle built on the classic SET principle.

Every card has four dimensions — count, shape, color, fill. Three cards form a valid match when, for every dimension, the values are either all the same or all different. Spot them fast. Clear the board. Outpace your opponent.
