If you really want to play free poker games online that have a bit of structure to them you're better off creating an account at an online poker site and playing their free play-money games. Players splash around and go all in with virtually anything. So any sense of traditional poker 'strategy' is really out the window. As all of the chips are free (or bought in bulk) they don't really have a real 'value' per se. What they don't offer, however, is any sense of 'real' poker play.
These can be semi-fun games to play as you can build a mass of free chips and climb a play-chip leaderboard to show your overall poker prowess. You can also play them directly online or via Facebook, like Zynga Poker.
