Frozen Bubble is a free Puzzle Bobble style computer game which is available on several operating systems including Linux, Mac OS X, Windows and the Symbian Series 60 line of smartphones. There is also a single player Java applet version.
The original Frozen Bubble was written in Perl by Guillaume Cottenceau, and uses the Simple DirectMedia Layer (SDL) library. The game features 100 levels and includes a level editor. Like many popular open source games, it features penguins a la Tux, who in this game shoot the coloured frozen bubbles to form groups of the same colour. Such groups disappear and the object is to clear the whole screen in this way.
