This stack was sponsored by a customer, wanting to put simple interactive puzzles on a website for home learning, during the Covid-19 pandemic in 2020. It is not possible to create a conventional puzzle; in the sense of pieces you can pickup, rotate and position on a board. The next best solution (which PuzzleStack uses) is a puzzle that involves the use of sliding tiles. This type of puzzle works much better with a computer mouse and on touch screens (like tablets and smartphones).
