so i just wanted to make a note, i ran a simulation of my third method and found that 1558 out of 100,000 cases ended in failure.
that's a 98% chance of success. unless the warden is evil, which given the puzzle may very well be the case, assuming he honestly picked prisoners at random, if you want to get out in a reasonable amount of time, I'd use my third method.

Good point. In real life there would've 23 funerals before the guaranteed solution had run its course. :)

It would be an interesting scheme to simulate.
