In this unique version of Fluxx, players collect single-digit numbers in order to form larger multi-digit numbers using mathematical operations. For example, if the Goal is 88 and you have Keepers for 1, 2, 4, and 5, you could play the New Rule called "Grafting" to combine your 4 and 5 into 45, then subtract the 1 to get 44 and multiply by 2 to get 88 and win the game! Because they need to be aware if a particular Goal will make your opponents win, students are doing constant mental math throughout the game, whether it's their turn or not.
