With two hours, this tutorial video will take you through the entire process to create your Tetris-style video game using the Python scripting language.
The video on the web is completely free and teaches you how to create the game using Pygame, a set of Python modules that allows you to create video games in two dimensions in a simple way.
This course is designed for middle-level programmers and some experience, but anyone is welcome to try to follow the steps outlined in it and learn to create or play for you.
Under Video description, you can also find instructions on how to install Pygame in Windows into another video, but all the final game code.
