A 'Blam!' is a set of 3, 4, 5 or 6 cards where the number on each card in the set represents an attribute of that particular set. [Many cards contain a number, a shape and a color.] For example, a '2' on a card could represent that there are 2 RED cards. The '3' on a card could represent that there are 3 SQUARES in the set. A '5' might represent that there are 5 CARDS in the set. No repeats are permitted. Points are awarded based on the number of cards in each set, and the game end when a player reaches the target score. Highest score wins! —description from the publisher
