The casino in Wiesbaden only has 5€/10€ games. Their website says that games depend on what people want to play, so even if that wasn't way more than I want to play with, I don't want to sit down at a 7 Stud game or something that I don't really know how to play.

And thanks for the Austria tip. Those games look a bit more my speed.

And according to googlemaps, Karlsruhe is about 1.5 hours away, so not having a car, that may be a bit difficult, but I'll give him a shout. Thanks guys!
