Sliding Puzzle is the famous 15-puzzle, a pocket brain-teaser that has challenged players for over a century. Fifteen numbered tiles sit in a 4×4 frame with one empty space. By sliding tiles into that gap, you reorder the whole board until the numbers run neatly from 1 to 15.
It looks easy and feels deceptively tricky. The tiles can only move into the single empty space, so reaching the spot you want often means temporarily disturbing tiles you had already placed. Solving it efficiently is a real test of patience and planning — and finishing it is hugely satisfying.
