Every card has four features: number (1–3), colour (red / green / purple), shape (diamond / oval / squiggle) and shading (solid / striped / open).
A Set is any three cards where each of those four features is all the same or all different across the three — never two-and-one.
1 red · solid
2 green · striped
3 purple · open
Number all-different, colour all-different, shape all-same, shading all-different — that is a valid Set.
- Tap three cards on the table. A legal Set is claimed instantly and the cards are yours.
- A wrong pick freezes you out for 5 seconds — look before you tap.
- The table always holds a Set: if 12 cards have none, three more are dealt.
- Round ends when the draw pile is empty and no Set is left. Most Sets wins.
