Where would I get a provably fair system coded like this? For a dice game that rolls the sum of two six-sided dice?

Ahh, I can understand SD's system clearly now thanks DannyHamilton. Still not convinced by other casinos who opt for the deposit once, withdraw later scheme as they're surely only getting one transactionID, so would they have to generate billions of secret numbers for each and every dice roll/card dealt/wheel spun? If so, surely they could manipulate that secret number?

Okay so it uses the transaction id.
I've seen casinos that are different from SatoshiDice in that not every single wager placed is a new transaction. They deposit money onto the website first, and then play with that, making only 2 transactions total (deposit and withdraw) does that mean these casinos are not provably fair?

I don't get exactly how a transaction id confirms that an online casino is not rigged. 

I've had a look at a lot of various different online Bitcoin Caisnos and most of them have a recurring theme being 'Provably Fair'. I've never seen this before on any other websites, but I am aware that it is very hard to achieve true randomness.

What makes something Provably Fair? Does it only apply for Bitcoins? Is it truly random?

Omg, I could only imagine!

Hello I've been glued to my laptop for the past week reading anything and everything about Bitcoins, I absolutely wish I knew about them 1-2 years ago! They would have been so useful as I was previously trading virtual goods through PayPal and Western Union with horrible transaction fees! 

But now the time has come, Bitcoin has a place in my heart, and I am looking forward to going on a journey with Bitcoin seeing where it can take me, and all the opportunities it will bring!

Wooooooo, and nice to meet all of you.
