A couple of weeks ago, I set you a puzzle based on prisoners escaping their captivity. Read it here if you haven’t seen it.
If you’ve given it some thought and are struggling with it, here’s a hint for you.
Clearly they’re not going to just open lockers at random. Think about, as a prisoner is in the room opening lockers, where he/she might get their next locker number from.
Happy puzzling!
