Press the start button to generate your beginning numbers.  The goal is choose a number that is divisible by your previous choice, or divides your previous choice.  Each new valid choice will raise your score, but an invalid choice will end the game.  See how high of a score you can get!

Note that the new numbers will be randomly generated, so it is possible that you will be left with no moves. Choose your divisors wisely!
