Answer on my riddle: Ask the trolls this question: "What would the other troll say if you'd ask him what the right tunnel is?"

Imagine the good tunnel is the left one.

The liar would say the right one, he lies about the *good* troll, which would say the truth, and say left.

The troll which speaks the truth, will also say the right one, because that will be the answer from the lying troll.

So you have to take the other tunnel.


As for Ann Neely's riddle: Is the answer Oil?
