World Series of Poker: Pro Challenge N-Gage download
There's no 'buy-in' for this demo
Being the N-Gage's only poker game, World Series of Poker: Pro Challenge has to be worth checking out, especially seeing as you actually have to try and read the physical reactions of the virtual players in order to call their bluff.
If you need more convincing, however, a quick go of the downloadable demo should help decide whether it's a good bet for mobile entertainment.
