Each entry is assigned a # of tickets based on the value of the items entered. The creator is the lower numbers and the joiner the higher numbers. Assumming the creator has winning percentage of A and the joiner has winning percentage of B (A + B = 100).
A random percentage P between 0 and 100 is generated.
If P < A, the creator wins. Otherwise, the joiner wins.
There is a secret server seed which is randomly generated for each game. This is revealed after you play.
There is a SHA-256 hash of the server seed and this is shown to the user on the Coin Flip page BEFORE the game is started.
Players may replicate past games using the below code:
$server_seed = "pmtrJ9kK5z2vfHgTYHtnBQr8cm3kdW5kt34Kd8KoAnS3jR5iDfsqernhmWqcNq8n";
$creator_percentage = 49.12;
$joiner_percentage = 50.88;
$hash = hash("sha256",$server_seed.":".$creator_percentage.":".$joiner_percentage);
$winning_percentage = floor(hexdec(substr($hash,0,13)) / 4503599627370495 * 10000) / 100;
echo "Winning percentage = $winning_percentage";
You can execute PHP code straight from your web browser with tools like PHP Tester. Simply copy-paste the code into the window and replace the server_seed, creator_coins, and joiner_coins for your own. Execute the code to verify the game.
