This was a very nice puzzle, with the exception of difficulty with some of the border pieces seeming to fit. I did not have that difficulty with the rest of the puzzle although I will say it was not as easy as I was anticipating. I would say an easy-medium. The pieces have odd shapes and it takes a while to realize that yes that funny little edge is the correct fit because another funny little pointy piece will fit in there. It often seems like cuts for a round puzzle in a rectangular one. But I enjoyed it and I think kids would enjoy helping out, do to the picture, especially in the 300 piece version.
