First of all. MY score of 2565 was completely legit. I got a royal flush and cashed in. So no matter while some may whine just beause they didn't get one, that doesn't make me any less the Poker Champ I truly am. So there!
The 5000 score is bogus. I figured out that once you start playing, if you hold the mouse cursor over the game, right click - and click "Play" instead of clicking on the Bet 5 (or Bet 1 thru 5) the game would run - and if you had a loosing hand, it woudln't charge the loss to your account. However, if you won, those winnings would go into your account. One can also reverse the effects of a "Double up" or a "4x" loss by right clicking and the clicking "Back". So you can play away, never loose any money and only gain. I got it up to about 2600 or so and then got another royal flush and left it around 5000.
The 50000 score is bogus. So I started from the beginning by clicking Play. Had a winnign hand and clicked "Take". Somehow the starting amount of 50 didn't get cleared or update, but 200 appeared after that. To test the value in there I saved that as a high score and it worked. He he he....
So the 500,000,000 was my crowning acheivement

. Started by clickong Play from the beginning and had several winning hands. Again the 50 stayed and the winnings just kept getting added to the right (least significant digits).
There was one more - I made the number so big that I'm guessing I overflowed the buffer and crashed part of the game that would let me report the high score. (Damn!).
So now the truth is out and a certain mr goody-two-shoes can stop complaining
I'm still poker champ!
