I searched this topic, but did not find an answer, so here goes:
I went to the mobile.blackberry.com website, clicked on games, free games, and downloaded Texas Hold'Em King game.
My question is, Why do I see posting referring to paying for this game and getting a serial number? Is the pay version different than what I downloaded?? It looks the same to me. Whats up with the pay version??

Magmic has updated Texas Hold'em King to version 2. If you upgrade to version 2 but your original was the free version from mobilebb, you will only get a 3 day trial period for the new Texas Hold'em 2. If you have a "paid" or registered version, you get to upgrade to Texas Hold'em 2 for free without the 3 day trial.

THK 2 has more elaborate head to head play. Strongly
advise that you try it out.

Also, currently the trial period on THK 2 is 7 days so
plenty of time...
