Choose a stack and race your partner! Fastest time wins. If you don’t have a timer, place an object between the players and the first one to finish grabs the object.
This can be played with 2 or more stackers as long as everyone has cups. For extra challenge, do a combination of stacks such as 3-3-3, 3-6-3 and Cycle all in a row or more than one of the same stack.
