+-------------+ | What is it? | +-------------+

Simple HTML5 game of a supersized Mastermind; from the original size of 4 all the way up to 10 slots.

+----------------------+ | How to run the game? | +----------------------+

Since I'm new in using GitHub, I don't know how to upload it so all you need is to click the green Code button to download it, what I did is to publish a Release, and upload it there; so you need to go there, Click here for the game, and click on codebreaker.html and the game downloads and runs from there.

Yes, it is in one single file. I figure out how to inject SVG into the same file.

Actually, the source code refers to a background image and 2 sound effects, they are not required and in fact, you may also prefer it this way as I am.
