How to play
Cliques is Xing’s open-source adaptation of the mathematical card game Set by Marsha Falco.
In this game, each card has four features: number, shading, color, and shape. Each characteristic has 3 possible variations.
To play, select a trio of cards. You score a point if that trio of cards is a clique, and lose a point otherwise.
A trio is considered a clique if for every feature, either all three cards have the same variation, or all three cards have different variations.
