The Play: The dealer shuffles the cards and lays twelve cards (in a rectangle) face up on the table so that they can be seen by all players. The players remove a 'Set' of three cards as they are seen. Each 'Set' is checked by the other players. If correct, the 'Set' is kept by the player and the dealer replaces the three cards with three from the deck. Players do not take turns but pick up 'Sets' as soon as they see them. A player must call 'Set' before picking up the cards. After a player has called 'Set', no other player can pick up cards until the first player is finished. If a player calls 'Set' and does not have one, the player loses one point. The three cards are returned to the table.
If all players agree that there is no 'Set' in the twelve cards showing, three more cards (making a total of fifteen) are laid face up. These cards are not replaced when the next 'Set' is picked up, reducing the number to twelve again. If solitaire is being played, the player loses at this point.
The play continues until the deck is depleted. At the end of the play there may be six or nine cards which do not form a 'Set'.
The number of 'Sets' held by each player are then counted, one point is given for each and added to their score. The deal then passes to the person on the dealer's left and the play resumes with the deck being reshuffled.
When all players have dealt, the game ends; the highest score wins.
