On the Subject of Graffiti Numbers

The answer to this puzzle is spray painted on the wall. Hurry up and punch it in!

  • The module consists of a graffiti wall containing nine painted numbers from 1-9. Each digit will only appear once. Warning: '7' and '1' look similar.
  • To disarm the module, you must spray paint the correct buttons in the order dictated by the rules below:
    • If there are more red numbers than green numbers, start at Rule #8 and progress in reverse order.
    • Otherwise, if there are more blue numbers than yellow numbers, start at Rule #6.
    • Otherwise, if there are more green numbers than blue numbers, start at Rule #4 and progress in reverse order.
    • Otherwise, start at Rule #1.
  • In each instance, if the rule is true, spray that number.
