Another suggestion:
Tabletop Simulator has a Jigsaw Join 2 add-on that is really great for doing puzzles. They allow you to rotate the piece by scrolling the middle mouse wheel while "holding" it.
Scroll wheel only works for people with mice. Two finger rotating only works on mobile. I think something that could work for laptops (or anyone really) is a tap to rotate by 90°. The pieces only have 4 sides, so there's only 4 possible orientations, anyway. Should be a good option for people that want more of a challenge.
