Maelstrom was created by Andrew Welch of Ambrosia Software, with art by Ian Gilman and Mark Lewis. It was ported to Linux and SDL by Sam Lantinga. The pictures, animations and sounds here are the originals from the open-source release of Maelstrom 3.0, repacked for the browser but otherwise unchanged; the artwork is used under the Creative Commons Attribution 3.0 licence. The game rules are rewritten from that release's source code, which is under the GNU General Public License. This is an unofficial fan remake.
