使用Python解决乌龟瓷砖拼图游戏

Introduction

This is a follow up of my previous article where we learnt to create a puzzle game using Python Turtle module.

But there was one important piece missing from the equation: finding the minimum number of moves needed to solve the puzzle (i.e. to remove all the tiles from the screen).
