Just recently won a steam game called Faerie Solitaire from steamgifts.com. Steamgifts is a site that lets you enter raffles submitted by other users. The whole thing is free and the only requirement is that you have more than $50 worth of games on your steam account. They also use Points system, it costs a certain amount of points to enter the raffle so that one person can't enter all the raffles. You passively get points as users make new raffles.
