The 15 puzzle is a sliding puzzle that consists of a frame of numbered square tiles in random order with one tile missing. The goal of the puzzle is to place the tiles in order by making sliding moves that use the empty space.Note: not all shuffles are currently solvable.
The great thing about being the only person committing to a repo is that you can do whatever the hack you want. And so I find myself merging broken code to master for #5, just for fun. I think the logic in solvability-tiles-game.pdf is flawed, because (I think I got it replicated)[https://github.com/JanDW/slide-number-puzzle/blob/e839ecac56ebf1a3668952ca1ee1cf9c15359e43/puzzle.js#L221]
I did fix solution checking, so that's good.
