Five red discs (Posted on 2005-09-07) Difficulty: 3 of 5
Paul shows nine colored discs (five red, two blue and two green) to five logicians.

After blindfolding them, Paul picks up the five red discs, sticks one on the forehead of each logician, and hides the other discs elsewhere. After removing the blindfolds, everyone sees the discs (all red) on the others' foreheads but not the one on his own.

After a few minutes, one of the logicians (that reasons a little faster than the others) correctly states the color of his disc. How does he work it out?

Paul, who is also a logician, is the one that states the disc is the color red. I think there is a word play on both times it uses 'his own' refering to the logicians and "color of his disc" still referring to the logicians but not really saying that its 'one of the logicians' who correctly states the color. Do you see what im saying or am i crazy?

Also it doesnt say there is a disk place on five logicians, but rather EACH logician. Again is paul one of the logicians plus the five, changing the odds a little?
