3 cards where each attribute is all the same or all different. Never two matching and one different.

Gameplay
12 cards are dealt. Tap 3 cards to claim a SET. Correct = +1 point. Wrong = −1 point. There is always a SET on the board — if one runs out, the board reshuffles itself. Game ends when the deck runs out.
