PrimePak® Card Game

Product Description

Think FACTOR! Don’t just multiply and divide. That’s what players must do while having fun playing rummy-like card games with this unique deck of 171 standard-size cards. Players form factor sets - for example 20=4 x 5 so the numbers 20, 4, and 5 form a factor set. The rules booklet defines four different card games, six deck levels, and includes math rules and strategies. Adapts to many levels. For 1-6 players or teams. Grade 2 and up.
