All rolls on CSGOPolygon.com are generated using a provably fair system. This means the operators cannot manipulate the outcome of any roll. Players may replicate any past roll using the below code:

$server_seed = "2754f7cc9e9e243711448401ea9d483067138a6b37c70c5d80b6c59943aa6996";
$lotto = "1135567382";
$round_id = "1";
$hash = hash("sha256", $server_seed . "-" . $lotto . "-" . $round_id);
$roll = hexdec(substr($hash, 0, 8)) % 15;
echo "Round $round_id = $roll";

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, lotto, and round_id values for your own. Execute the code to verify the roll.

To keep our rounds fair and truly random, we utilize the provably fair system. At the beginning of a round, the server generates a salt, and a winning percentage to identify the round. These two elements are concatenated to create a round hash as follows:

$secret = "s92kAbkjWk";
$winningPercentage = "54.20192427";
$ticketAmount = "10000";
$hash = md5($secret . ":" . $winningPercentage);

When the round is complete, the server will choose a winner using the following formula:

$winningTicket = floor(($ticketAmount - 0.0000000001) * (($winningPercentage / 100)));
echo "Winning ticket ($hash) = $winningTicket";

Where the number of tickets is the the total jackpot amount in coins. After choosing a winner, the server will reveal the round's salt and winning percentage allowing you to back calculate the other quantities as necessary.
