how to use this script on freebitco.in to roll 9999 lucky numer
any script that works  have tested that script
<?php
set_time_limit(360); // number of seconds to run script, default is 30

$_jackpot = $_10k_pz = $_prize1 = $_prize2 = $_prize3 = $_prize4 = $_prize5 = $_lo = $_hi = 0;
$tries = 20000; //Number of tires
$c=0;// Iteration count
do {
// nonce = $c;
// 12 char server seed string, 16 char client seed string
$nhash = hash_hmac('sha512',$c.':'.seed_string(12).':'.$c,$c.':'.seed_string(16).':'.$c,false);
$_no = round(hexdec(mb_substr($nhash, 0, 8 ))/429496.7295); // Changed from ceil() to round()

?>no work for me its nothing guys any other script that works is really great
