Moola (website)
Moola is a Canadian based online gaming website currently open to United States and Canadian residents. Players receive free credits to wage against other players in return for watching a 10, 15, or 30 second video advertisement and randomly answering a trivia question about it. By extending credits to the viewer of the advertisement, players have funds to place bets against other players without risking any of their own money. These player may then 'cash out' the accumulated winnings for real cash once the equivalent of $10 or more has been reached.
Moola ranked 11th on PC World magazine's "The 15 Best Places to Waste Time on the Web" in 2007.
