I ordered three of this series of puzzles for my children, ages 12, 9 and 6, for Christmas. One puzzle took them (working collectively) all evening to finish assembling. But the fun wasn't over yet. Then all the adults in the household helped with the "search and find it" part of the puzzle - which took us all weekend (every time we walked by we'd try to find those few tiny missing ones!). What a great idea. I'm very happy with these.
Great transition for 6 year old who loves puzzles. We started with large piece puzzles, then to 100 pieces and now 300 piece puzzles. The finished product is beautiful and children will have fun finding the hidden pictures.
