Interchangeable Sliding Puzzle

This pirate themed puzzle has interchangeable tops (numbers and picture). The pieces are easy to grip and move around. How do you get the pieces into the right place? That's for you to find out! I made it in studio. You could make "treasure" for a puzzle race as a prize. Think about how amazing this set could be! There would maybe be a series of these in different themes. This is a great way to pass the time when you are bored. You could even make your own tops! Please support this idea. I did not copy it off of anyone; I got the idea and built it before I signed in to Lego Ideas.
