Comp points is a term used both in online and land-based casinos. The term refers to reward points that can be used to claim various prizes.
If you have played in casinos before, you are probably aware that virtually every casino has a VIP programme. Players who continuously play in the same casino and big spenders get to climb the VIP ladder and earn various rewards. To advance up the ladder, a player has to accumulate a number of points specified by the casino, and those points are known as comp points.
In some cases, especially when it comes to online casinos, casino operators have exclusive shops available on their platform. You can visit those to spend your previously earned comp points.
Naturally, the details of VIP programmes and specifics regarding comp points vary from one casino to another, but the general idea behind them remains the same.
