What is the name of this kind of word puzzle?

Question

The puzzle has questions that you have to match three variables like this:
"There was a circus of five brothers. They were Adam, Jack, Evan, Derek, and John. They were an acrobat, a juggler, a clown, a muscle-man, and a motorcyclist. Find out which brother performed what in which order.
1. Derek performs before Jack but after the juggler.
2. John is not a clown
3. Evan does not perform after the muscle-man.
4. The acrobat does not perform either first nor last."
Then there's three 5 x 5 boxes put together labeled with names and orders and performances. P.S. I just randomly made the question above up so please don't attempt to solve it. It probably does not have a solution anyway.

Answer 1

Adam the juggler is first.
Dereck the acrobat is second.
Jack the clown is third.
Evan the muscle-man is fourth.
And, John the motorcyclist brings the show home in fifth.

That was one of the hardest logic problems I have ever done! :] LOL!

Answer 2

With the presence of the boxes, the puzzle is know even more specifically as a "logic grid" puzzle. I found that on Wiki...

Answer 3

Yep, they are logic problems. You can buy Logic Problem puzzle books where they stock crossword books.

Answer 4

Those are logic problems. My daughter loves to solve them, and they drive me bananas.
