If you are new to Power Apps, you may want to watch them first to get a feel for the gameplay and the app's behaviour: SlidingP – Installation and Setup How to Build a Sliding Picture Puzzle in Microsoft Power Apps Introduction This article walks through the design and implementation of a 3x3 sliding picture puzzle game built in Microsoft Power Apps.
