Sliding Number Puzzle is a classic tile-sliding brain teaser where your goal is simple: rearrange scrambled numbered tiles back into the correct numerical order using as few moves as possible. Built in pure HTML5, it runs instantly in any desktop or mobile browser without installing anything. The numbered tiles slide into an empty space one at a time, and every move counts toward your final score.

The game features a clean, distraction-free grid that keeps your focus on the puzzle itself. Solving it efficiently requires planning several moves ahead rather than sliding tiles randomly – a key strategy that separates beginners from seasoned players. The fewer moves you use, the better your result, giving you a clear target to beat on every retry. That built-in challenge makes it genuinely hard to put down once you start optimizing your approach.

This free online number puzzle is a perfect fit for anyone who enjoys logic games, brain training exercises, or classic sliding puzzles like the 15-puzzle and 8-puzzle. It works great as a quick mental workout during breaks, making it popular with students, office workers, and puzzle enthusiasts of all ages. Whether you search for number tile puzzle games, free sliding puzzles online, or classic HTML5 brain teasers, this game delivers exactly what you need – no fuss, no cost, just pure puzzle-solving satisfaction.
