- [How to Solve a 9×9 Sliding Puzzle?](https://slidopuzzle.com/how-to-solve-a-9x9-sliding-puzzle/): The 9×9 sliding puzzle, or 80-puzzle, contains eighty numbered tiles and one blank space within a 9×9 grid. The objective is to arrange the tiles in ascending order from left to right and top to bottom, with tile 1 in the top-left corner and the blank in the bottom-right position: Only orthogonal slides into the adjacent blank are permitted. Of the 81! / 2 ≈ 1.2 × 10¹⁵³ possible states, exactly half are solvable due to permutation parity and blank row parity (odd grid). This article provides a rigorous, hierarchical reduction strategy that solves any solvable 9×9 instance in 900–1500 […]
- [How to Solve an 8×8 Sliding Puzzle?](https://slidopuzzle.com/how-to-solve-an-8x8-sliding-puzzle/): The 8×8 sliding puzzle, known as the 63-puzzle, consists of sixty-three numbered tiles and one blank space arranged in an 8×8 grid. The goal is to order the tiles in ascending sequence from left to right and top to bottom, with tile 1 in the top-left corner and the blank in the bottom-right position: Only orthogonal slides into the adjacent blank are permitted. Of the 64! / 2 ≈ 1.3 × 10¹²⁰ possible states, exactly half are solvable due to permutation parity and blank taxicab parity (even grid). This article outlines a disciplined, hierarchical reduction method that systematically solves any […]

The objective is to arrange the tiles in ascending order from left to right and top to bottom, with tile 1 in the top-left corner and the blank in the bottom-right position: Only orthogonal slides into the adjacent blank are allowed. Of the 49! / 2 ≈ 1.5 × 10⁶⁴ possible states, exactly half are solvable due to permutation parity and blank row parity (odd grid). This article presents a disciplined, progressive reduction strategy that transforms the 7×7 puzzle into a sequence […]
- [How to Solve a 6×6 Sliding Puzzle?](https://slidopuzzle.com/how-to-solve-a-6x6-sliding-puzzle/): The 6×6 sliding puzzle, known as the 35-puzzle, contains thirty-five numbered tiles and one blank space within a 6×6 grid. The objective is to arrange the tiles in ascending order from left to right and top to bottom, with tile 1 in the top-left corner and the blank in the bottom-right position: Movement is restricted to orthogonal slides into the adjacent blank. Of the 36! / 2 ≈ 3.7 × 10⁴¹ states, exactly half are solvable due to permutation parity and blank parity constraints for even grids. This article details a hierarchical, row-by-row reduction strategy that systematically solves any solvable […]
- [How to Solve 5x5 Sliding Puzzle?](https://slidopuzzle.com/how-to-solve-5x5-sliding-puzzle/): The 5×5 sliding puzzle, or 24-puzzle, consists of twenty-four numbered tiles and one blank space arranged in a 5×5 grid. The goal is to order the tiles in ascending sequence from left to right and top to bottom, with tile 1 in the top-left corner and the blank in the bottom-right position: Only adjacent orthogonal slides into the blank are permitted. Of the 25! / 2 ≈ 7.8 × 10²⁴ possible states, exactly half are solvable due to permutation parity and blank positioning rules. This article presents a rigorous, incremental strategy that reduces the 5×5 puzzle to a sequence of […]
- [How to Solve a 4×4 Sliding Puzzle?](https://slidopuzzle.com/how-to-solve-a-4x4-sliding-puzzle/): The 4×4 sliding puzzle, known as the 15-puzzle, comprises fifteen numbered tiles and one blank space within a 4×4 grid. The objective is to arrange the tiles in ascending order from left to right and top to bottom, concluding with tile 1 in the top-left corner and the blank in the bottom-right position. This configuration represents the standard goal state: The puzzle permits only orthogonal slides into the adjacent blank space. Of the 16! / 2 ≈ 10.5 trillion reachable states, exactly half are solvable due to permutation parity constraints. This article outlines a rigorous, layer-by-layer method to solve any […]
- [How to Solve a 3x3 Sliding Puzzle?](https://slidopuzzle.com/how-to-solve-a-3x3-sliding-puzzle/): The 3×3 sliding puzzle, commonly referred to as the 8-puzzle, consists of eight numbered tiles and one blank space arranged within a 3×3 grid. The objective is to rearrange the tiles into ascending numerical order from left to right and top to bottom, with the blank space positioned in the bottom-right corner. This article provides a structured, step-by-step methodology to solve any solvable 3×3 sliding puzzle efficiently. Fundamental Principles The puzzle operates under strict movement constraints: a tile may only slide into an adjacent blank space—horizontally or vertically, never diagonally. The total number of possible configurations is 9! (362,880), but […]

- [Sliding Puzzle Solver](https://slidopuzzle.com/sliding-puzzle-solver/): What is Sliding Puzzle Solver? The Sliding Puzzle Solver is an advanced web-based tool that combines the classic sliding puzzle game with powerful artificial intelligence algorithms. Unlike traditional puzzles, this solver doesn’t just let you play—it can automatically solve any configuration using sophisticated search algorithms like Breadth-First Search (BFS), A* with heuristics, Iterative Deepening A* (IDA), and a custom strategic algorithm that mimics human problem-solving approaches.
