Number Crunch: Again, a very nice and useful math game. In this case balls are going up (instead of down) and you have to destroy them before they reach the top. Believe me, adding up to 10 is a very important skill. It's needed everywhere where's regrouping involved.
Instructions: Click the numbered balls to create a sum of 10. The more balls you use the higher your score. Click bombs to remove adjacent balls or clocks to pause the movement.
