Description from the developer
A challenging math puzzle game where all you have to do is add all of the numbers on the board together. But there is a catch as you can only add equal numbers together or numbers whose sum equals a number already on the board. For example, you can add 3 and 3 together because they are equal. If 7 is on the board you can combine 5 and 2 together. Although 5 and 2 aren't equal their sum is 7 which is on the board.
