There are still some casinos who serve German residence as before, these are mostly ones who don't going to apply license there, regulator (what's that funny fcking long name of them who no normal person can pronounce?) want casinos to get compliant already before next summer if they wish to get licenses.
Some have decided to leave German and don't apply for license at all, these ones don't have to care about these deposits limits, max spins, max bets etc... which are coming, they just stop acceting German players at some point, for now there still are some decent ones who are not compliant with new regs with purpose as they do leave when have to.
