Playing on your phone? Slide Puzzle's header now shows a smart app banner that matches your platform — iOS players get the direct link to the app right away, with Android support on the way.
We also gave our 15-puzzle solvability guide some love. It now covers more configurations, explains the classic Guarini knight-move puzzle, and answers common player questions in a clearer FAQ section — handy if you've ever wondered why some slide puzzles can't be solved no matter how hard you try.
