Now that we have the personal attendants, how about having a gambling night?
I mean, nothing fancy, just a few events:
Roulette: The attendant rolls 2 d20s. Everybody can bet on one number. The winner gets half the take.
Craps: This we can play with just the dice and a cup. Probably one of the better events since everyone can play (bet for or against the roller)
Slot Machine: Lock down three dice cups. If the rolls all match in value, the player gets double their money. If they get all 12s or all 2s, they get 10x their money. Otherwise they get nothing.
etc, etc....
