instruction-img

A SET consists of 3 cards in which each of the cards' features, looked at one-by-one, are the same on each card, or, are different on each card. All of the features must seperately satisfy this rule. In other words: shape must be either the same on all 3 cards, or different on each of the 3 cards; color must be either the same on all 3 cards, or different on each of the 3, etc. Examples see below

For example, the following are SETs:

example1

All three cards have the same shape, the same color, the same number of sybols and they all have different shading.

example2

All three cards have different shapes, different colors, and different numbers of symbols and they all have the same shading.

example3

All three cards have different shapes, different colors, different numbers of symbols and different shading.

Uh-oh!

The combination you chose is not a set. Try again.

Awesome!

You found a set.
