is the answer sent with the puzzle?

Yes, we do include the solution with this puzzle. Try not to look though.

looking for a difficult puzzle that can’t be solved in 10 minutes. Is this the one I’m looking for?

No, this puzzle is a challenge. I gave one to a relative & their extended family worked on it off & on thru Xmas vacation. My nephew did finally get it:))). It is addictive!

After you solve the puzzle does this become a dust collector?

No! I have it out on my coffee table & anyone who sits near the table picks it up and gives it a try. My grandchildren work at it every time they are over:)

Does this come with a cover?

Thanks for your interest. The version on amazon does not come standard with a cover; however a cover is available as a $4 option. The version on CreativeCrafthouse site does come standard with it.
