Crown Jewels — Who Stole Them?
Lesson 10 of 16
About this lesson
The Crown Jewels have been stolen! Four animals each make a statement. Exactly one of them is telling the truth — and from that single constraint, you can figure out who stole the jewels. This is the classic "one truth-teller" logic puzzle. The method is always the same: try each suspect, check all four statements, count the truth-tellers. The one that gives exactly one is the answer.
