Divide the grid into orthogonally connected regions such that no two regions of the same size share an edge, and enter a number into each cell equal to the size of its region.
The region borders form a single loop that travels orthogonally on some edges in the grid (possibly including some edges along the perimeter of the grid). The loop may not turn on icy vertices, and may cross itself only on icy vertices.
Example Puzzle (5x5)
Main Puzzle (8x8)
Solution code: The number of vertical edges used by the loop in each row, from top to bottom. (For the example puzzle, the solution code would be 24442.)
