four riddles - now with answers!
You've probably heard at least some of these before, but I felt like posting them anyway, and we all need a break from the usual politics and videos. These are four of my favourite riddles, mostly because none of them are trick questions. Feel free to email us for hints or answers, and why not leave your favourite riddle(s) in the comments?
1. You have eight blocks; they are completely indistinguishable from each other, but one is slightly heavier than the others. You are also given a balance. How do you find the heavy block using the balance only twice?
2. A castle is surrounded by a moat, as shown in the image. You are given two thick boards, four meters long and about a foot wide. How do you get across to the treasure in the castle? (You can't just float on the boards because the moat is filled with huge sharks, like bigger than the one in Jaws.)
3. You come to a fork in the road. One way leads to certain death, the other leads to the next village. Two twins are standing nearby. You've been told that everything one says is a lie, and everything the other says is the truth. You can ask only one question; both twins will answer. What do you ask them to figure out which path to take?
4. You are alone on the ground floor of a house. Upstairs there are three lightbulbs, but you can't see them (or their light) from where you are. The switches for the bulbs are downstairs and unlabelled. If you can only go upstairs once, how can you figure out which switch turns on which bulb?
