In short, I'm saying that, assuming bitvegas is using, and not filtering in it's favor, a good random number gen, then the fairness is provable. It would be great if you could also prove the randomness.
I think I prefer it how it is; it's cleaner, and every player can totally mess up any team of players' attempts to fix the deck by picking his own random words.
I do like the idea of having a pre-published list of house seeds, indexed by game number, and having the game number in the chat before each deal so I don't have to keep clicking on the green checkmark.
But I came here to say:
1) how about having a racecard showing the next few pig races, rather than just the next one. Let me bet on multiple upcoming races at once rather than having to go back to the betting terminal between every race.
2) maybe add some copies of the existing games but for real-money players only. Now that the casino is teeming with life (thanks to the millibit faucet) the minefield games are often occupied by playmoney players. It would be nice if there were rooms which the playmoney players couldn't tie up.
3) did you say you added poker? I didn't find it yet.
