A host at a Caesars property in Las Vegas showed me some an internal document that outlined how much free play people received for various levels of play.
400-499HV = $75 casino play
500-599HV = $100 casino play
600-749HV = $150 casino play
750-999HV = $200 casino play
1000-1499HV = $250 casino play
1500-1999HV = $350 casino play
2000-2999HV = $500 casino play
3000-4999HV = $750 casino play
5000-7999HV = $1,250 casino play
8000+HV = $2,250 casino play
So the question is what does "HV" mean and how is it computed?
