are the odds the same for spinning a gold vs all the other colors?
I'd like to know that too.
Is the wheel 'fair', or is it weighted more towards black and less towards gold?
Do you plan to make a "provably fair" version of the game, like how SatoshiDice and bitZino are, so we can be absolutely sure you've not cheating?
The game is provably fair - they mention it in the FAQ and even provide their formula. I have crunched 1 of my TX's (randomly selected) so far to confirm and the results were what I expected (in preparation for being moved out of pending in the gambling list).
Looking at the formula used it is impossible for them to weight it (unless they manually send out all payments), they could try selecting a secret that leans 1 way or the other using previous bets to judge the weight, but should any player pick the way the table leans they could exploit it to their advantage.
What is this gold colour you speak of ? I see red black and green.
