We've sunk hours -- and we mean hours -- of our lives into Zynga Poker's online rooms, where players can enter tournaments or table play with virtual chips. No actual money changes hands, and Zynga offers a small bankroll of chips each time you play. Play well, and you can rise up through the ranks. Extra play chips can be bought for real money, but take our advice: be a smarter poker player and learn to play with the free bankroll, craftily beating real worldwide opponents and Facebook-connected friends. The new iPad-ified interface is crisp and easy to use.
