Dukes of Hazzard Hold 'Em. We don't normally put movie tie-ins in the chart, but this is isn't too bad a version of head-to-head poker where a) you can't lose any real money, and b) you get to beat a computerised Jessica Simpson. It sticks to fairly standard Poker rules - try to make the best possible hand of 5 cards, and bet (or bluff) to try and get Daisy's money - though proper card-sharks will spot that there are limited options as to what you can bet, and not much in terms of "all in" possibilities.
On top of that, it's not like there's any chance of "reading" Jessica/ Daisy's glazed, lifeless expression (she does, however, change her outfit if you take all her money). It also seems to make some odd judgements when you and Daisy have similar hands, and there's a bug where the game freezes if you fold on the first hand of a new pack of cards, but it's still a reasonable introduction to the game - we suspect real-life opponents may be more cunning, if not quite so easy on the eye.
Controls: Mouse click on menu options to fold current hand, check (ask the other player what they want to do without betting upfront), bet, or raise.
Tips: Of course you're not playing with real money so, if you're on a fast net connection, you can always just "Reload" the game if your total goes below your original $250.
