A Game of Primes

A number will be displayed. Type in a prime factor of a number and hit enter. The number will be divided by that factor and the result will be displayed. If the number shown is ever prime, type in the number itself and hit enter.

If you enter a number that isn?t prime or isn?t a factor, you lose a life (shown by the three + signs at the top center of the screen). You have 30 seconds to factor each number and your score will be increased based on the number you factored and how much time you had left. Instructions are in game as well.
