Classic pencil and paper game. Add a single line (vertical or horizontal) between 2 dots. If you complete a 1x1 box you earn a point and get another turn. The winner is the player with the most points (boxes).
Goal of Add It Up is to select numbers that add up to the target sum. You only have a limited amount of time to do so. The more numbers you select to get to the target sum, the higher your score will be. The faster you solve a sum, the higher your score will be.
