Set is a game that requires quick thinking, a lot of patience and a panache for seeing in multi-dimensions. The object of the game is to identify "sets" of 3 cards. Each card has unique features: number (1, 2, or 3); symbol (diamond, squiggle, or oval); shading (solid, striped, or open); and color (red, green or purple). A "set" consists of 3 cards on which each feature (taken separately) is either the same on all of the cards, or different on all of the cards. Remember, if 2 are... and 1 is not, it is not a "set"!
