The Blackjack game has been fixed. I'm sorry, I was unaware that it was no longer working.

To play Blackjack, go to preferences (inside the game), create blackjack account and then select play Blackjack. Once the account is created, you won't need to create an account again for the remainder of the round. I'll eventually chance this so it doesn't reset when the game does.

If you haven't played it before, check it out. It's actually a pretty cool game.
