, what are the requirments to get the jackpot
0.0001 btc bet?
Yup. You just need to make some 0.0001 (or above) bets and some pretty good luck.
Jackpot:With each bet 0.1% of the bet amount goes right into the jackpot. You hit the jackpot if your seed meets a certain criteria and you have wagered at least 0.0001 for this particular roll. The probability for this to happen is 1:1,048,575 and the exact algorithm is:
function isJackpotHit($serverSeed, $clientSeed, $incrementalNonce) {
$hash = sha1($serverSeed . '-' . $clientSeed . '-' . $incrementalNonce);
return substr($hash, 0, 5) == '00000';
}
