Errrr... What the hell were you thinking?
You have a problem with your math and the decisions the CPU makes... I played it the first time and thought, "Something's wrong here..." So I played it five more times to make sure it wasn't just my imagination.
1: Billy The Kidney cannot bluff or call with anything less than a straight, with the odds sitting at a rough 1/32 to pull a straight in 5-card-draw this makes the game incredibly frustrating if you were able to bust out the other players in the first five hands, which I did every time.
2: One of the characters has the single best ability in the game and makes the rest plain stupid to play as. (I can change color or suit? Yeah - that's a balanced mechanic...)
3: Pezza is correct - Jessica ALWAYS knows what the player has - five of the hands that she was a part of I was holding a face pair and she could pick it out, each time she was holding a hand that had a 1/5 - 1/10 chance of pulling a pair from the deck that would have been higher than mine, but a 1/2 - 1/4 chance of pulling two-pair... That's just unforgivable CPU cheating.
4: If at any time you are holding a straight or better the rest of the characters, some for NO REASON, will try to bet their entire stack to bluff you out of it.
5: Through dumb luck I wound up with a straight flush and everyone folded - with one of them holding a flush... Again, unforgivably bad logic in the code.
6: Why in the hell is my raise limit capped at 40 when there's an All-In button? This only means that the programming the CPU follows dictates that it can't comprehend higher than 4 variables... Sloppy programming. (50 or above raises the required paths and outcomes from around 256 to over 1024.)
7: 15 rounds is also too short for a four-player game to have a discernable winner, as once I would up with the exact score of my opponent (Jessica James)
To put it in a better way to the 14-year-old NG users:
DIS GAM IZ TEH FAIL!, LOLZ!
(the 3 is for the graphics - they're mildly entertaining.)
