Many of the casinos recommended by Casino Spy offer their players access to VIP schemes, which are often based on a ranking system in which higher ranking players are awarded more benefits and perks than their lower ranking counterparts.

Players usually collect VIP points, which accumulate to unlock higher status or access exclusive prizes and benefits.

Because higher VIP ranking is most often achieved by betting big or playing regularly, it pays to play, and the more time you spend with a casino, the more special entitlements you are likely to receive. Rewards you can receive as an online VIP or special promotion winner include international holidays, casino bonuses, cars and cash prizes.
