Our jigsaw puzzles are more difficult to put together than traditional puzzles. They are essentially meant for youths and adults (14+). Even though there are not a lot of puzzle pieces, the pieces are quite small and uniquely shaped. For most of our customers, it takes them around 3 to 4 hours to put together the medium (A4) size. However, lots of our customers buy them for their children as well. It’s a lot of fun, they say. If your child is really young, we would recommend our nature puzzles or all of the small (A5) sizes which are the easiest to put together.
