Hello!
I am working on a jigsaw puzzle project with 4 pieces. I want that, when the user has completed the picture successfully, a hidden message is shown and a sound is played. But I don't know how to tell app inventor to check if all the pieces are in the correct place (x and y coordinates) in the canvas. I would appreciate it very much if someone could help me, if possible providing an image of the blocks.
This project has similar features.
