The Application Catalog at the Maemo wiki lists a new game: MammaSnake.

You can download the MammaSnake installation package, mammasnake_0.9-1.deb (”works on real N770 device!” notes the site), or the MSnake source code, mammasnake-0.9.tar.gz.

At Neave Games, which sells a version of Snake for Nokia phones, this description of the game appears:

This game has been around since sometime last century, but it only recently took off since it came as standard on Nokia mobile phones (or ‘cellphones’ as those crazy Americans like to say)….

The idea is to guide the snake to eat the food. The sooner you eat, the more you score. And just like real food-eating snakes, the more you gobble, the fatter you become. And don’t eat the walls — they taste awful.
