online poker in Germany is in the process of becoming completely legal. Some poker rooms are already trying to join them.As of July 2022, GGpoker, PokerStars, partypoker and 888poker have already launched separate .de domains and base their relationships with players on German gambling laws.Dial- 888poker.de should work and load this only for Germany.
