Simple Poker is an easy way to get some Texas Holdem practice.
This started off as a study in probabilities and strategies in game play. The computer opponent will play according to its odds and it will try bluffing from time to time. Your best bet is to play your odds.
In version 2, Ive added a multiplayer mode. While "Chip" might be challenging at the start, it is far from human. So, practice with Chip then try your skills against another person on Game Center!
Both the multiplayer and the practice modes are head to head Texas Holdem. With this version, Im also using big and small blinds and a standard turn order.
