table players are "rated" when they play. High-end properties only rate play of $25 minimum bet and up. In order to qualify for a comp room a typical level of play is $50-100/day for 4 hours. There is a higher level, RFB (room, food, beverage) that often requires $250 or more average bet for four hours. You find out what you need to do to qualify in a particular hotel by asking a casino host. Often they quote you higher numbers than you actually need.
