In this game you will learn to calculate fast. You will roll a ball across a three-lane motorway with the arrow keys or by tapping left or right on the screen. On the way you have to try to avoid the white blocks. If you touch one, you will have to restart the game. You will also have to solve multiplication equations and roll through the right answers with the ball. Each time you will see rows with three numbers, with only one of these numbers being the right answer. The game starts out slowly but then you will see the ball roll faster and faster. Every time you start a new level, you will get a new background color and new speed. Good luck!
