I think thats a good idea. There is this puzzle that I found once. Seems like an option.
bulding with 5 floors
a. Adam does not live on the top floor
b. Bill does not live on the bottom floor
c. Cora does not live on either t - Building with 5 floors
ding with 5 floors
a. Adam does not live on the top floor
b. Bill does not live on the bottom floor
c. Cora does not live on either the top
or the bottom floor
d. Dale lives on a higher floor than Bill
e. Erin does not live on a floor adjacent
to Cora's
f. Cora does not live on a floor adjacent
to Bill's
I think it's fine to have zebra-puzzle (we just added it) and to then have a different logic puzzle exercise too.
I've changed the title a bit

I agree. We might not want to add them in problem-specifications, but they're brilliant for the prolog track.
PR added for the floors puzzle: https://github.com/exercism/prolog/pull/239
I've added three logic-based puzzles:

I'm open to more ideas!
zebra-puzzle
seems like the Prolog exercise.Three drawbacks I see with it are: 1) the problem instance is repeated across the internet, and 2) solutions that fit this problem instance is repeated across the internet (in particular on Rosettacode), 3) if one were to solve this exercise in Prolog without copy-pasting from existing solutions, perhaps a smaller instance of the problem in another exercise might work?
zebra-puzzle
has 5x5 dimensions; how about a problem with 3x3 dimensions with a completely different theme? Perhaps a theme where you have to solve a murder; three persons (Butler, Countess, Lawyer), three potential murder weapons (Letterscale, Candlestick, Telephone), and three rooms (Bedroom, Kitchen, Attic). This should force the student to at least understand what they're copy-pasting.I don't know if it ruins the free-form structure of the exercise, but I've always wanted to create a puzzle generator for this type of exercise. If we did that, the exercise should be able to handle arbitrary instances of the problem.
