Set is a simple but interesting

card game played with a

deck of 81 cards. Each card has a group of

symbols which represents one possible choice from the following set of options:

- Number: one, two, or three symbols
- Color: red, green, or purple
- Shape: ovals, diamonds, or squiggles
- Pattern: open, half-shaded, or solid

All 81 combinations are represented once each.

A set is a group of three cards which are either all the same or all different for each variable.
