Hi! Welcome to Set. If it's your first time playing, this page might help you out a bit.

Set is a card game, played with cards that look like this:

As you can see, each card has four characteristics:

1. Shape -- oval, diamond, or squiggle

2. Color -- purple, red, or green

3. Shading -- empty, striped, or full

4. Number -- one, two, or three

A set is made up of three cards. These three cards make up a correct set:

Can you see what the rule is? Here's another example of a correct set:

A set is made up of three cards for which each characteristic is either the same across all three cards or different across all three cards.

Another way of thinking about this is that if two cards are the same in one characteristic and the third is different in that characteristic, then that group of three cards is not a set.

Why isn't this group of cards a correct set?

That's right! Two of the cards are purple, while the third is red. How about this one? Is it a set?

You're right, that's not a set! Two of the cards are striped, and two of the cards are red, so it's DOUBLY not a set.

So let's try something interactive now. Here are four cards. Can you find which three make up a set?

Click to make a selection. Once you've picked three cards, I'll let you know if it's a set or not.

If you've mastered that example, let's try a harder one with six cards:

If you can figure this one out, you should be ready for the full game. Go click PLAY to see how quickly you find all six sets!
