What makes a 3x3 puzzle "Legendary"?
Legendary puzzles are configurations that require near-optimal moves (often 28-31 moves) to solve. They represent the upper limit of difficulty for a 3x3 grid.
Is every puzzle in this collection solvable?
Yes! Every puzzle is mathematically verified using a BFS (Breadth-First Search) algorithm to ensure it is solvable and to determine the exact minimum move count.
What is the "God's Number" for a 3x3 sliding puzzle?
The maximum number of moves required to solve any 3x3 configuration is 31 moves. Our legendary collection contains many puzzles at or near this limit.
