RULES

The object of the game is to identify a 'Set' of three cards from 12 cards laid out on the table. Each card has a variation of the following four features:

(A) COLOR:

Each card is red, green, or purple.

(B) SYMBOL:

Each card contains ovals, squiggles, or diamonds.

(C) NUMBER:

Each card has one, two, or three symbols.

(D) SHADING:

Each card is solid, open, or striped.

A 'Set' consists of three cards in which each feature is EITHER the same on each card OR is different on each card. That is to say, any feature in the 'Set' of three cards is either common to all three cards or is different on each card.

For example, the following are 'Sets':

All three cards are open; all are ovals; all have two symbols; and all have different color.

All three cards are green; all are ovals; all have different numbers of symbols; and all have different shading.

All have different colors; all have different symbols; all have different numbers of symbols, and all have different shadings.

The Magic Rule

If two are... and one is not, then it is not a 'Set'.
