I am playing Snake on my custom LED display, which I made with an individually programmable ws2812 LED Strip controlled by an Arduino. Which is a quite simple alternative to using a LED Matrix.
While I was at it, I tried to make the game reusable and created a Snake Game Library, which I uploaded at Github. So if you would like to check out the source, you can find it at: https://github.com/emanuelk/Snake-Game-Library-for-Arduino
