Fifteen Puzzle: 15 Digits

A sliding number board fills the screen in Fifteen Puzzle: 15 Digits. Fifteen square tiles sit inside a 4x4 grid, and one space stays empty. The numbered pieces need to return to ascending order, beginning in the top-left position. The layout echoes the classic 15 puzzle many players know from childhood, yet a mixed board still takes real logic to sort.

How to play?

Shift a tile into the empty slot to change the layout. Only pieces next to that gap can move, and the vacant square travels across the grid with each slide. Place all numbers in sequence from 1 to 15 to finish the board. The game tracks how long the solve takes. It also records the number of moves. Lower move totals and shorter solve times set a new personal record.
