How to Play
Find three cards where every feature is either all the same or all different.
Click or tap three cards to check them. A correct set is recorded and replaced by new cards. If your three cards are not a set, they flash red and count as a wrong answer.
When the board has no set, use Add 3 to deal three more cards. Adding cards while a set is already visible counts as a wrong answer.
