And before they entered the room, they were told that at least one of you hundred logicians has your forehead painted blue. And then every time that they turned on the lights, so that they could see each other, they said OK, once you've determined that you have a blue forehead, when the lights get turned off again, we want you to leave the room.

Y cada vez que ellos prendan la luz, de tal manera que puedan verse unos a otros, ellos dicen Ok, una vez que tu determines que tienes la frente pintada de azul, cuándo las luces se apaguen otra vez, queremos que dejes el cuarto.
