Description: An ADDicting little game of, yes, numbers. Do you have the right cards to complete your 5 x 5 square before your opponent? The sum of 2 cards you play must have the SUM of the 3rd card - if the SUM is more than 10 or more ... drop the 1 (tens place). Then, the SUM of the 3rd and the 4th must equal the 5th. Watch for the STEAL and BOMB cards! A LITTLE thinking ... a LOT of fun!


What makes it Hot Diggity great: Kick your brain into high gear with SUM it! As players build their 5x5 grids, the equations fall into place horizontally and vertically ... MIND BLOWN! Once you get the hang of it, this math card game is absolutely addicting! 


Ages 7+

SUM it!
