In the Snake game you control a serpent, which is roaming around the garden looking for apples. Be careful, though, because when you catch one, not only will you become longer, but you'll move faster. Running into yourself or the walls will end the game.
Scroll up your trackball when the games asks to "press up to play".
Note Pad (also known as Notes List or Notes) is another sample of an Android application from Google with very basic functionality. It features a simple text processor and lists all notes in a linear structure. Users can only add, edit and delete notes.
