Number Up is a logical puzzle game. At this game, you need to be good with math and to have good reflexes. There will be squares with numbers in them and you need to move with a ball on the squares. At every square will be a number. The number can be negative or positive, and when you pass with a ball over squares it will count all numbers and negative and positive. You can play this game all-time long while you get a negative score. So, for that, you need to move balls only at positive numbers or in negative that have a small value.
