You have to know that there are huge restrictions to play. As far as I know and heard only players living in this region are allowed to play (3,5% of germans population) , no free choice of players and tables, no moneytransfer between players, etc.
So far away from a regulate market like in other juristications.

He came with the name Cincinnati, a kid with no ace in the hole,
on a hot poker pot, Cincinnati, had staked his heart and soul. (Lyrics by Ray Charles)
