What I like about this game is that you do not need to win to gain ranks.
Also, I found this little tidbit in the Pogo news :
Pogo Llama: What are some of the different features in the new HD version?
Pogo John: The biggest new feature to the game is the updated art style. This game features new backgrounds, animations, and card art that looks great when playing either in full screen or standard mode. Another change we made was to how hands are dealt within the game. Previously the game dealt cards at 100% random, however this was changed a little to ensure that this is more user friendly. For those who like a challenge though, fear not! The game is still very challenging and depending on your hand, you may need to start over.

So the cards that are dealt are not 100% random. I guess was too difficult to win when it was all random?
