In 1998 Assembly programmers who typically participated in Demo competitions did a series of size coding challenges. The first one was a Snake game (Nibbles), all in a DOS environment. The winning entry was 48 bytes long.

There were also some creative attempts that took less than 48 bytes and got disqualified. One of those encode the entire game in a series of empty folders using the folder names.

Edit: the original Hugo size coding competitions were created by Claus-Dieter Volko (Alias: Adok).

the winning 48-byte entry isn't really snake (nibbles), as the length of the snake grows with every move, rather than with every bit of food consumed. looks more like tron.
