Making the video game Snake is a classic challenge, especially on a TI-84. If I’m being completely honest, I had no idea where to start, so I copied a snake program from another site. However, the program was very buggy, so my job became making sure it could run on my calculator.

Ultimately, I changed the code to fit on my screen, adding a score counter, a high-score counter, and a landing screen. I hope you enjoy!
