DarkworldPHP is a version of DarkworldOnline. Users open a
page in their browser, enter a nickname and start playing
against the other players, which are online at the same
time. The socket data transfer of DarkworldOnline is
simulated by approximately 30 PHP page request per second.

The funpic.de version was removed (16.12.2016).
Ohhh, try the old non-multiplayer version!
