There are 81 unique cards in a deck, and the board will start out with 12 cards.
Each card has four characteristics:
- Color (orange, green, blue)
- Shape (circle, diamond, rectangle)
- Shading (solid, hollow, patterned)
- Number of shapes (one, three, six)
The goal of the game is to make "sets" based on certain criteria.
A set is three cards where, for each of the four characteristics (color, shape, shading, number), either:
- All cards match in the characteristic
- All cards differ in the characteristic
This is an example of a set:
