There exist several good applications and entertaining games of poker for iPhone, I would like to have a look at one of them, which is the official application of Apple - Texas Hold'em Poker – surely one of the best.
This game completely differs from online poker websites. There is a multitude of poker game variations, as well as a great number of very well made decors. You have the possibility to begin with the solo mode in order to train and slowly but surely you will see that the game gets more and more interesting and that sums are getting higher constantly.
The quality of animation is superb, the characters are realistic. For your convenience, videos with 3D decors are included.
When you turn your iPhone to a horizontal position, you get a classical view of the game, this time without videos, almost a bit similar to the sites of poker which you may know from the internet. With Texas Hold' em Poker, you will be able to play with your friends in multi-player mode via Wifi.
