The fifteen puzzle was a popular download on the legacy SlideMagic PowerPoint template store (RIP). It is easy to recreate in SlideMagic 2.0 and I have just added it to the library of slides. Search for something like “fifteen” or “block” in the app and it will show up. This slide can be tricky to make in traditional presentation software as you need to get 16 boxes to line up nicely in a square.

PS: This is probably the only slide in SlideMagic so far where you have to make an adjustment when you switch aspect ratio. A wider slide layout will stretch the square into a rectangle. I added 2 versions of the slide to the library.
