Players collect Keepers consisting of single digits while attempting to reach an ever-changing multi-digit Goal. At the easiest level, only number recognition is required, such as a 2 and a 1 make 12 to meet the Goal "Dozen". As the difficulty level increases, players must use addition, subtraction, or all four basic operations in order to reach the Goal. For example, to reach the Goal of "101 Spotted Dogs", a player with the Keepers 9, 2, 5, 4 and 7 could win because 9 x 2 x 5 + 4 + 7 = 101. Includes 100 cards and rules for 2-6 players. Ages 8 and up.
