### Re: My write-up of the "Blue Eyes" solution (SPOILER A

"The guru speaks English" is not an axiom. " I see someone with blue eyes is a statement in English" is an axiom. "This is not a trick question" is just a cop out for a lack of clarity. But even if I accepted that reasonable assumptions are permissible in a logic puzzl...

### Re: Puzzle : gambling game

I might be misunderstanding the rules, so let me clarify - three players each put up \$1, and two lose their dollar while the third walks away with \$1 plus his original dollar? If this set up is correct, then imagine the game from the perspective of the "house". Each round, the house takes ...

No, I think the recursion still works... The base case is still the same (if there's only one blue-eyed person, then a "Secret announcement to all the other blue-eyed people" is vacuous and changes nothing), and the inductive case still works (if n blue-eyed people would leave on night n,...

This question starts by assuming the answer is generally correct regarding how the people/dragons come to the conclusion that they must leave the island/transform into birds.

The argument here is that the fact that there are Green eyes is mutual knowledge, not common knowledge. For it to be common knowledge all dragons must know there are green eyes (1), they must know the other dragons know that there are green eyes (2), and they must know the other dragons know they k...
