This describes the classic "15 Puzzle" (or a larger variant). The goal is to arrange 30 numbered tiles in ascending order (1-30) by swapping adjacent tiles. There's no single solution algorithm that's concisely describable; solving it efficiently requires search algorithms (like A* search) or heuristics. The puzzle's solvability depends on the initial arrangement and the size of the grid. A computer program would be needed for an optimal solution.
