Frozen Bubble is a free software clone of Puzzle Bobble for a variety of home and mobile systems. Gameplay Frozen Bubble's protagonist is a penguin a la Tux, the mascot of Linux and popular feature in many free software/open-source games. In this game, Tux has to shoot colored frozen bubbles to form groups of the same color. Such groups disappear and the object is to clear the whole screen in this way before a bubble passes a line at the bottom. There is a single player mode and a multiplayer mode via Split screen, LAN and Internet. The game features 100 levels and includes a level editor. History In 2001, Guillaume Cottenceau started writing the original Frozen Bubble game in Perl while using the Simple DirectMedia Layer (SDL) library. The music was made with FastTracker II by demoscener Matthias Le Bidan. Alexis Younes and Amaury Amblard-Ladurantie created the sprites and background graphic artwork with GIMP. The game is released under the GNU GPL-2.0-only. There is a version programmed in Perl and another one programmed in Java. The Perl-version runs on POSIX-compatible operating systems, e.g. Linux and the BSDs, while the Java-version runs on any operating system that supports Java. The 2006 released version 2.0 introduced multiplayer play via LAN and Internet. Two players can also play on the same computer (Split screen). The chain reaction mode (where fallen bubbles will zoom back up to complete triplets, possibly causing more bubbles to fall and thus creating more combos) is also available in network mode as of Version 2.0, and greatly changes the mechanics of the game. Version 2.0 introduced artwork rendered with Blender. The Frozen Bubble Team provides builds only for Linux distributions, while ports to other Unix-like operating systems (such as Mac OS X and the BSDs), Windows and mobile phones exist from the community.
