A man is traveling to a town and comes to a fork in the road. If he goes left, he goes to the liars' village. If he goes right, he then goes to the village of truths - which is where he wants to go. However, he does not know which way is which. He doesn't have time to go both routes, so he approaches a stranger who is standing in the middle of the fork. The stranger says he may only ask 3 questions and he will answer them. The man asks, "Are you from the village of truths?" The stranger says, "Yes!" However, the man is still facing a dilemma: If the stranger was from the village of truths he can only tell the truth, but if he was from the village of liars, he would say he was from the village of truth. So then he asks the stranger, "Are you telling the truth?" The stranger says, "Yes!" But sadly this leaves the man in the same position as before. Can you figure it out ? Answer

You are killed in a plane crash and find yourself at 2 doors : one leads to heaven and the other to hell. There is a troll at each door and the trolls are identical in every way.

One troll will always lie to you regardless of your question, and the other will always tell you the truth. Only the trolls themselves know which will lie and which will be truthful, and that is all you are told. What one question should you ask? Answer

A boy was at a carnival and went to a booth where a man said to the boy, "If I write your exact weight on this piece of paper then you have to give me USD 50, but if I cannot, I will pay you USD 50."

How did the man win the bet? Answer

  • The British man lives in a red house.
  • The Swedish man keeps dogs as pets.
  • The Danish man drinks tea.

This last riddle that is considered widely to be one of the most difficult riddles, has been widely attributed to Einstein and is often known as Einstein's riddle. Though that attribution is widely debated.

The answer is sometimes right under our nose. It is just our failure to recognize the obvious and complicate the simple that leads us to believe that answers to these riddles are tough to solve.

The answer to the riddler's riddle (5 letter word: fully im a food, take away first letter im a crime...) is grape. First, grapes are fruits, so they're food. If you take away the g, you get rape, which is a crime. Take away the g and the r and you get ape, which is a primate and an animal. Take away the g, r, and a and you get pe: an abbreviation of physical education, which is a school class. - Sir [October 7, 2014]
