All of Husks employees are demons whose souls he owns. He has occasionally used them when betting in games.
Only employees he's very attached to have souls he will never bet.
His main casino is named High-Roller Casino, he has several smaller ones as well, but that's the main one.
Weapons are not allowed in his casino, they must be checked in at the entrance to avoid fights over lost games.
Managing to sneak a weapon in will most likely get the demons working the doors in trouble or even killed. It also means an automatic ban from any of Husks casinos.
Husks casino contains a main lobby and gaming room, several private rooms which can be rented out, a bar and a few bedrooms. He lives in the casino and usually has the demons he cares about stay in rooms as well.
The rules of his casino (that I've come up with so far) are:
1 ) no weapons past the door
2 ) don't harass the staff
3 ) don't bet what your not willing to loose
4 ) once you've bet/gambled it, you can't go back on that
5 ) if you can't pay up then your betting with your soul instead
6 ) fighting over games will get you kicked out
