This is a variant of the classic sliding tile puzzle, where the puzzle is coiled around a cylinder. The goal is the same: to put the tiles back in the correct order. Unlike the classic 15-puzzle, this version is solvable because of the extra connection between the first and sixteenth squares of the frame.
IMPORTANT: This is the frame for the puzzle.
You will also need to purchase a set of tiles (
