If you want to watch or join the gambling, take into consideration that the Casino has a strict dress code. For men this means shirt, jacket and tie. (Shirt and tie without jacket are not considered formal dress in Germany.) Women should dress 'appropriate'.
No need to panic, guys, if you don't have these items with you. In case of need a tie and a jacket can be borrowed from the Casino reception.
This applies, however, only for the part with the roulette and poker tables and only after 2 p.m. when the gambling starts. For the guided tours in the morning and to visit the part with the slot machines there is no dress code at all, normal casual wear is all right.
