A man who lives on the tenth floor takes the elevator down to the first floor every morning and goes to work. In the evening, when he comes back, on a rainy day, or if there are other people in the elevator, he goes to his floor directly. Otherwise, he goes to the seventh floor and walks up three flights of stairs to his apartment. Why?
Well since you know you are not one of the cursed you can go down a tunnel yourself but you want a good answer from the rest so you split the groups in three leaving two left. Let those two go down one tunnel and the other six go down two separate tunnels as well. When you all meet back 20 minutes later either you have found the tunnel or someone else. Now look at the rule majority rules. If the group of three has 2 people saying it wasn't down that tunnel then you should know it wasn't down that tunnel and one of the liars have been spotted. Same with the other group of three as well as the group of two. Judging by the answers the groups gave you, you should go down the right tunnel and head to safety while the spirits possessing the two people should leave and all is well.
You have 3 boxes. One of them contains a prize. You were allowed to pick just one of them.
You pick - and it's empty.
With 2 boxes left, you now have one box in your hand and another box in front of you. If given the chance to exchange your box with the box in front of you, would you do it? Why, and why not?
(The 'Google Riddles' are interview questions those who wish to get hired were asked).
In the beginning, with 3 boxes, things were simple. You had a chance of 1 in 3 to find the prize. NOW we know that one of the boxes is empty but you still made a guess of 1 in 3, now you have a new choice of 1 in 2. Your probability goes up and that is why you SHOULD CHANGE THE BOX.
Don't feel bad if you disagree, this riddle has been hotly debated.

This was Gollum's final riddle from The Hobbit:
"This thing all things devours;
Bird, beasts, trees, flowers;
Gnaws iron, bites steel;
Grinds hard stones to meal;
Slay king, ruins town,
and beats a mountain down."
