Table of Contents Preparation Introduction Import modules and define contants Create the main game screen Creae the data structure of the board Let's draw the tiles The game logic Define the missing functions Preparation In this tutorial, we are gonna use Python 3.8 and Pygame v1.96.  For the installation of Python and Pygame, please follow the documents found on each webiste. Python: https://www.python.org/ Pygame: https://www.pygame.org/ Introduction As you can see from the picture above, we create a board with 15 green tiles and one white tile which represent a empty slot. Our gaol is to place all the 15 green tiles back into its sorted order, namely: A B C D E F G H I J K L  M N O If we click on the tile "F", the tile will slide down south. And if all the tiles are back into their sorted order, you won the game and quit the game. That's pretty much the gist of the game, later you could add other features to the game.
