Brain Teasers & Puzzles

Brain Teasers are problems that make you think — ones that make you go "Aha!" when you get the solution.This group is not for mindless word games. If that is what you want — seek elsewhere.WHEN POSTING A NEW PROBLEM, GIVE IT A DESCRIPTIVE TITLE, not just "Another problem" or "Solve this!"Before posting a problem, please check through the previous threads that it hasn't been posted (and solved) before.Welcome.
