Video Tutorial of Snake Game in JavaScript

Making a Snake Game is not only fun, but it can also help you develop problem-solving skills and the ability to break down complex problems into smaller ones. So, I highly recommend that you watch the above video tutorial to the end.

In the video, I tried to explain each line with comments and show which code does what in the game. But if you wish, you can skip the video tutorial and continue reading this post to create a snake game on your own.

Steps For Creating Snake Game in JavaScript

To create a snake game using HTML, CSS, and JavaScript, follow the given steps line by line:

1. Create a folder. You can name this folder whatever you want, and inside this folder, create the mentioned files.
2. Create an index.html file. The file name must be index and its extension .html
3. Create a style.css file. The file name must be style and its extension .css
4. Create a script.js file. The file name must be script and its extension .js

To start, add the following HTML codes to your index.html file to create the game’s basic layout. The “play-board” container is empty now, but it will be filled with snake bodies and food elements later using JavaScript code.
*HTML Code will available soon.*
Next, add the following CSS codes to your style.css file to make the layout of the Snake game. Remember that control arrow keys are only shown on small devices, such as phones. If you prefer to display them on all devices, you can easily modify the media query code.
*CSS Code will available soon. *
Finally, add the following JavaScript code to your script.js file to add functionality for the snake game. This code will handle the logic behind the snake’s movement, eating food, updating the score, and detecting collisions with walls or its own body.
*JavaScript Code will available soon.*
In the code, you can see that the current speed of the snake is 100 milliseconds, which determines how quickly the snake moves on the game board. You can easily adjust this speed by changing the value in the “setInterval” function at the bottom of the code.

To understand the code more deeply, you can watch the above YouTube video tutorial or read the comments within the code and experiment with it.
