From the Creators of Equate

“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 cards. The four card games are Factor Rummy, Prime Challenge, Prime Solitaire, and Prime Canasta. In all four games players form factor sets. Because 6 = 2 ¥ 3, the numbers 6, 2, and 3 are called a factor set for purposes of these games. Prime wild cards can be used for prime numbers only. The included rules booklet defines the four card games and six deck levels. Math rules and game strategies are also discussed. For one to six players or teams, ages 7 years to adult.
