Gambling means you put something at risk (consideration) to play a game (like poker or blackjack) for a prize (like money). ClubBluff.com is not a gambling site because you join the "club" to get benefits like discounts on goods and services and the opportunity to play in tournaments for prizes. The tournaments are part of the club promotion. ClubBluff.com operates within the "sweepstakes" rules where they are legal and excludes people from joining who live in those states and countries where they are not. To better grasp the concept, think of network television shows or other promotions that offer sweepstakes and you get the idea behind ClubBluff.com.
