PROVABLY FAIR




Play with confidence! We guarantee that every game you play at bitcoin.com is
completely fair.

Instead of just taking our word for it, we make available all of the information
you need to verify that our game is fair.

The reason that we can guarantee this is that your web browser supplies a random
number that we must incorporate into the random number generator in a provably
consistent way. Our server starts by choosing a private server seed for the
random number generator that your computer doesn't know. Your computer then
sends us a random number that we must incorporate into the seeding of that
random number generator.

To manually verify a game that has been played, please use the "Verify Game"
button on a specific game.


THE NITTY GRITTY DETAILS

Before the game has started, a random seed number is first chosen by our server.

We then create an SHA-256 hash of this server seed and send it to your web
browser. This hash serves as a sort of encryption of the original seed number
chosen by the server. From this hash you can not identify the seed number
chosen, but you can later use it to verify that we did not change the seed
number afterwards.

These steps take place before any credits have been played by the user.

Your web browser then sends our server a random seed number. Your web browser
just selects any random number, although technically there is nothing preventing
the client from sending any number it wants. The point is that our server has no
way of knowing what this random number will be.

After the server receives this client seed number, it combines the server seed
and the client seed into a single final game seed. For example, if the server
seed was 7UDVbLn6Ct2a4ZHLHVPGu6MoccaZZ3hbzkwUoLxDSEKU and the client seed was
1293771171, then the final game seed will be
7UDVbLn6Ct2a4ZHLHVPGu6MoccaZZ3hbzkwUoLxDSEKU1293771171. The server is required
to use the server seed that it picked earlier, since the client can later use
the previously received server hash to verify this. Therefore, the server has no
control over what the final game seed will be, and therefore has no way to
manipulate the outcome of your game.

Finally, this game seed is used as the input into the Mersenne Twister
algorithm, which creates a random number sequence that is used to select random
numbers for your game.

Once the game is finished, the server reveals the server seed that it initially
chose. The client can then verify that the hash of this server seed does indeed
match what the server originally sent before the game started. Your web browser
will automatically verify that everything was legitimate. The JavaScript source
code that checks this is publicly available at
https://games.bitcoin.com/static/.
