Frankfurt's is at the airport. Only 3 table games and restricted hours. Even the slots are only 12 hours a day.

Wiesbaden is the VIP casino of Germany. Strict Suit and Tie dress code and high limit gambling. Opens at 3pm only.

Mainz is a 'regular' casino but doesnt open until the evening (after 5pm)

Sometimes table games dont start in european casinos until 10pm.

Be prepared to pay to get into all 3 of these casinos and you will need a minimum of your passport as ID.

Sorry, I dont have any scans of the current chips in use.
