AZsPCs - Balto's Puzzle - Description
Each of the 25 puzzles is played on a regular hexagonal grid. The puzzles differ from each other only in the sizes of their grids, which vary from order 3 to order 27. For this contest we'll generally refer to a grid of order n as being of size n .
Each grid has k - 1 moveable tiles, numbered from 1 to k - 1, where k is the number of cells in the grid.
Initially, each puzzle's tiles are distributed randomly among its grid's cells, leaving one cell empty. Example starting grid for n = 3
Your goal for each puzzle is to find a sequence of moves which relocates each tile to (or close to) its home cell, and does so with as few moves as possible.
