How to Play?

Upgrade is a puzzle game which will test your logic to the limit. You play a ball and initially you will have a score of 10. Your objective is to upgrade your score by jumping on the wheels at the one of the numbers. Your score will be calculated with the numbers using the modulus operand (%) The modulus operand works this way: your resulting number is the remainder of the first operandus divided by the second one. In this game, the first operandus will always be your current score and the second operandus is the number that you jump on. After you get the result number, your actual score will be added, substracted or multiplied by this result number, depending on the sign on the wheel. So for example, if your initial score is 10 and you jumped on a wheel with + sign, and you jumped on top of the number 4, 10%4 =2 and 10+2=12 so 12 will be your score after the jump. if at any time your score after the jump is 0, your ball lose a life. Use the Up arrow on keyboard to jump and use the mouse wheel to zoom the scene. Left click and drag the mouse to rotate the scene. You will be required to obtain a certain minimal score to win a level and on each level you will get new initial score and new score requirement.
