This one is nice,however might be known to You...
There is a prison with 100 captives in the solitary cells. Every night the guard will pick one of the prisoners(at random) and allow him to spend a night in a living room with a lightbulb(which is not visible from the cells). Prisoner can toogle the bulb,if he wishes,but if he does,he must guess who spend a night in the room before him. If the guess is correct,they are all realesed,if not they would be all killed.
Captives have one night to discuss a plan,but after that night,one of them(picked intentionally by the guard) will be killed.
What shalll they do ???
