There's nothing like cold, hard cash to drive people to action. In this case, Zynga is giving away 1,000 bucks every hour for 24 hours if you play eight of its most popular games: YoVille, Zynga Poker, FarmVille, PetVille, Cafe World, Treasure Isle, Mafia Wars and FrontierVille. After you play a game, it will be checked off in the game bar that appears above each game (see pic below).



When you've played all eight, your name will be entered into the next hourly drawing for $1K. The contest has already started today and will end tonight (Monday night) at 11:59 p.m. PST.

Please note: The contest is open to United States citizens over age 18 only -- sorry international fans, looks like you're going to have to sit this one out. :(

Also, here's a dirty little secret: You only need to load the game to get the checkmark to appear on the game bar, you don't actually have to 'play' them for it to count.
