Looks pretty good, even though it's un-polished. Thanks for adding it so quickly! Another suggestion: When you open a game and someone plays it, add a notification (similar to what you would see if you played someone) stating if your bet won or loss. Would be easier then watching your balance or checking the log all the time.

Also, do you have a rule regarding multiple accounts during testing?
Saw this guy (LuckyBit) and I'm pretty sure he had 3 accounts.

Another thing:
You have some unused space next to the create game box.

You should consider adding a bet history there (Maybe last 5?) for ease of use as switching pages is annoying if you bet a lot and want to know if you won.
