Basically, you get locked in a room and you have to solve the puzzles in the room to get out. There are various clues within the room that you have to put together in order to solve it. A lot of places will use different themes to shake things up, (Harry Potter, Alice in Wonderland, etc)
In a sort of hair brained way I can see the logic behind that.
Prison sucks but so would life on the run if they broke out and escaped.
So they must have seen the chance and figured it would be better in the long run to serve their sentances and be truely free at the end of it.
But prison still sucks and they got the chance staring them right in the face so they did the next best thing, go out and get a bunch of shit that will either directly or indirectly through selling it make their stay more comfortable.
I mean they got caught on cctv so tough shit but if they had been smart enough to not nick the stuff and just use a payphone to get a relative or mate to give them some shit to smuggle back in it could have been a good plan, or at least a better one than straight up escaping.
Worst one I’ve ever been in was a Death Note Themed room. You could actually solve it within 10 minutes if you had seen the series before (I hadn’t). That should never happen in a well-designed escape room.
Then I watched the series and wished I hadn’t. Fucking Misa.
