Waiting for your support, thank you.
You have to building a puzzle, piece by piece. You'll need a clip art image of a puzzle that can be ungrouped and modified in PowerPoint. When you ungrouped the puzzle clip art and change the fill color to match the background color of the side.
Place the image that you want to reveal underneath the puzzle image. Now you duplicate the slide and then remove a puzzle piece from the clip art. Continue to do this until the entire image is revealed.
