On the Subject of Gitgutting Graffiti Numbers

Vandalising a wall is a crime. Luckily, this is a job for defusers who had recently broken the Burglar Alarm.

  • 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.
  • Use the first applicable table, then spray certain numbers in order from top to bottom.
