Nick Yee on elegant logic puzzles:
…an elegant logic puzzle is one that can be told to anyone age 10 and up and doesn’t rely on gimmicks, but always seems impossible to anyone when first told. In other words, the problem is tough but the solution is satisfactorily simple once explained. The solution doesn’t involve a person or tool that wasn’t explicitly stated in the problem itself…
Then he goes on and asks you two elegant logic puzzles. For a curious mind, both of them are extremely rewarding to muse over and the solutions are clean and elegant too. Go solve them if you haven’t already.
