In this game, you sling balls at a snaking line of balls trying to make matches of three same colored balls. As you progress through the levels, the snaking patterns and the backgrounds change and become more difficult. Each time you make a combination of three matching balls, you will answer a subtraction fact. The problems that you will be faced with are based on the facts you're working on. This game is a challenging yet fun way to practice and learn the times tables!
