Kill some time and give your brain a little exercise at the same time with this simple game. You start with a random number and then start dividing by single-digit primes (2, 3, 5 or 7). When you can't do any more divisions you 'bump' the number -- multiplying by 10 and adding any single digit. You win the game by reducing the original number to 1.
