I am sorry, it should be "rounded off" and not "rounded up". I shall correct this on the website. So any number below 0.5 will be rounded down to 0.

OH... I changed my test script from ceil() to round()...

With ceil()
[Counts out of 20000 tries]
Jackpots: 1
10000 prize: 3
0000-9885: 19766
9886-9985: 202
9986-9993: 15
9994-9997: 13
9998-9999: 2

With round()
[Counts out of 20000 tries]
Jackpots: 4
10000 prize: 1
0000-9885: 19788
9886-9985: 191
9986-9993: 9
9994-9997: 8
9998-9999: 4

round 2,3,4,5...
[Counts out of 20000 tries]
Jackpots: 1
10000 prize: 0
0000-9885: 19765
9886-9985: 201
9986-9993: 23
9994-9997: 7
9998-9999: 5

round 6...
[Counts out of 20000 tries]
Jackpots: 4
10000 prize: 1
0000-9885: 19793
9886-9985: 184
9986-9993: 14
9994-9997: 4
9998-9999: 5

it's a lot harder to hit 10,000 using round instead of ceil but it's still possible! it took 120,000 rolls before it came up again, but it does!

Code:

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()

$_jackpot += ($_no == 8888);
$_10k_pz += ($_no == 10000);
$_prize1 += ($_no >= 0 && $_no <= 9885);
$_prize2 += ($_no >= 9886 && $_no <= 9985);
$_prize3 += ($_no >= 9986 && $_no <= 9993);
$_prize4 += ($_no >= 9994 && $_no <= 9997);
$_prize5 += ($_no >= 9998 && $_no <= 9999);

$c++;
} while ($c <= $tries);
echo '

function make_rand($l,$h) {
mt_srand(make_seed());
return mt_rand($l,$h);
}
function make_seed() {
list($usec,$sec) = explode(' ', microtime());
return (float) $sec + ((float) $usec * 65536);
}
function seed_string ($itr) {
$charSet = str_shuffle('ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz0123456789');
$ranStr = null;

$ranStr[] = substr($charSet, mt_rand(0, strlen($charSet)), 1);
}
return implode($ranStr,'');
}

it's still free bitcoins and dogecoins! so no complaints from me! lol
