Pressing the screen causes your numbers to jump up!
Pressing the screen causes your numbers to jump up. When your numbers fall on a cylinder, they will add or subtract the numbers on the cylinder. When your numbers are greater than 9 or less than 0, the game ends. When your number falls on a square pillar, if your number is not equal to the number on the square pillar, the game ends. Clicking on the screen allows your number to jump once, and double clicking on the screen allows your number to jump twice. Double clicking on the screen allows your number to jump continuously over two cylinders, but not over any square pillar.
