A casino’s payout percentage depends upon the state. At American Casino Guide you will find a state by state listing of payout percentages for casino games. But as I mentioned in my earlier articles, most land-based casinos payout a minimum of 70% to 80% while online casinos payout percentages range from 70% to over 98%. This is the case for Liberty Slots Casino who pays out the highest rate of 98.41%. The land-based casinos are required by state law to pay out certain percentages. Online casinos, on the other hand, will set their RTP at a higher rate to attract more online players.
