Gambling has strong links with prostitution in Victorian Europe but, even as single-purpose establishments, gambling houses and casinos flourish in all cities. The nature of the establishment varies with the local area and clientele. The proletariat often bet on the outcomes of prize-fights and animal fights; many also play cards in public houses that dedicate rooms for the purpose. Dedicate casinos are vast, lavish and invariably rigged. Gambling (accompanied by drinking) is without a doubt the primary form of entertainment for Europe.
