Cliques is an open-source game of Set.

In this game, each card has four characteristics - color, transparency, parts, and shape - and each characteristic has 3 variations.

To play, select a trio of cards. You score a point if that trio of cards is a "set", and lose a point otherwise.

A trio is considered a "set" if, for each characteristic, all three cards have the same variation, or all three cards have different variations.
