Slide Matrix is the timeless sliding-tile puzzle, rebuilt with buttery-smooth animation and free to play instantly in your browser with no download. Slide numbered tiles into the single empty space until they line up in order, from top-left to bottom-right. Pick your challenge with selectable 3x3, 4x4 and 5x5 boards, and rest easy knowing every shuffle is checked for solvability, so you are never handed an impossible layout. The game tracks your move count and elapsed time and saves your personal best for each board size, so there is always a record to beat, whether you are optimizing for the fewest moves or the fastest solve. A subtle celebration greets a solved board, and the clean, high-contrast tiles stay perfectly legible on a phone. Simple to learn and endlessly satisfying to optimize, it is a classic brain workout for any quick break.

How to play

On desktop, click any tile next to the empty space to slide it in, or use the Arrow keys or WASD to slide a neighboring tile into the gap. On mobile, tap a tile beside the gap to slide it, or swipe in the direction you want a tile to move. Arrange the tiles in ascending order with the blank in the bottom-right corner. Tips grounded in the real mechanics: first, solve the top row and left column first, then treat the rest as a smaller puzzle, since those edges lock into place; second, on the 4x4 and 5x5 boards, solve the last two tiles of a row together using the standard rotate trick rather than forcing one at a time; third, chase the fewest-moves record once you can already solve it, planning short sequences instead of nudging tiles one by one.
