Learn How to Code a Classic Snake Game (Part 1)

In this series of videos I will code a Classic Snake Game from start to finish, talking you through my entire thought process along the way because I really do believe this type of project is one of the best way for new programmers to learn.

I am going to be using the MIT Scratch platform, but most of the methods and coding principles I use to create this snake game will be applicable in just about any coding platform or language (e.g. Java, Python, etc.) although different languages/platforms will have their own quirks and their own methods for working with graphics. I chose the MIT Scratch platform because it is highly visual and easy to get started with making it a great choice for learning the basics of programming. It's also a free platform so anyone can take this project for a spin and start to learn.

Because of the length, I've divided this snake game tutorial into 4 parts:
