Our system generates the result for each round by using the SHA-256 hash of 3 seperate inputs:

1. The "last seed" is a SHA256 hash of last generated roll.
2. The "server seed" is a SHA256 hash of 16 cryptographically secure random bytes, generated once on every hour.
3. The "salt seed" is a random number, generated for this roll.

Players can replicate any past roll by using the code below:

  $seed = array( 
          'last' => "VGrWGG3ulG1mvJcZpIKBYbjKlzDWYKgTrIQ7pTCKAE75oj5O2Pp01JKninkg8A9z",
          'server' => "d0bfbcf5e737a1d2d88e4b1d4f0b8eb53fa0b47637aefce9d686538a250dcef9",
          'salt' => 280
        );
  
  $mergedseed = implode("-", $seed );
  $hash = hash("sha256", $mergedseed );
  $roll = hexdec(substr( $hash, 0, 10)) % 10000;

  echo round((double)($roll / 100), 2);
