You are in a Jail.

There are two switches outside of the jail. Every 5 minutes a guard will come and get someone (any of the prisoners) and he will be taken to the two switches.

Every time someone goes to the switches he must move one and only one switch from on to off or off to on. It can be any of the two.

The guard can pick who goes and he can take whomever as many times as he pleases.

You have to tell the guard when everyone has gone to the switches. If you tell him everyone has gone and even one person has not gone they will be fed to the crocodiles and you and all of the prisoners will be locked for life, if you tell it correctly you'll all be set free. You will only have a chance to interact with the prisoners once, this is before the guard comes and starts taking you to the switches.


It's 100% possible, just think outside the box... Good luck. It's a bit hard.
