A Java-enabled browser is required to play, and registering with the site is not required (though recommended, as many players will not play with unregistered users). All major aspects of the Java client, games and website are also available in English. The site is independent and free from advertising, except for indirectly advertising the games themselves.
All players begin (by default) in the game manager, which is used by players from many countries. New players having difficulty getting started can introduce themselves to one of the English-speaking communities for advice and help.
BrettspielWelt has an optional meta-game for its members, in which each game played earns experience points, credits and resources for the player. The metagame facilitates the building of smaller communities, set up as towns, in which players can meet, chat and play.
