MATH? SHA256 Roulette / Lottery computable?
<p>There is a website where you can play roulette, you can put on the colors only (red, black = double, green = 14x)</p>

<p>The rolls are computed by the following way:</p>

<p>There is a serverSeed EVERY 24 hours its different
This is a precomputed value generated some time in the past.
Seeds are generated in a chain such that today's seed is the hash of tomorrow's seed. Since there is no way to reverse SHA-256 we can prove each seed was generated in advance by working backwards from a precomputed chain.</p>

<p>There is a lotto and round_id too but they are given only the serverSeed is hidden until next day.</p>

<p>Example:</p>

<pre><code>$server_seed = "39b7d32fcb743c244c569a56d6de4dc27577d6277d6cf155bdcba6d05befcb34";
$lotto = "0422262831";
$round_id = "1";
$hash = hash("sha256",$server_seed."-".$lotto."-".$round_id);
$roll = hexdec(substr($hash,0,8)) % 15;
echo "Round $round_id = $roll";
</code></pre>

<p>This is how rolls are generated with making a new hash everyround as the round ID increments by 1 every roll, the serverSeed and the lotto remains the same whole day.</p>

<p>There is also a history page on the website where you can check every rolled color and number in the past.</p>

<p>My Question: Is there anyway to compute the next roll by the already rolled numbers? (I dont talk about reversing the SHA256 serverSeed or anything like that!!!)</p>

<p>But really isnt any math in this?</p>

<p>I know its MIGHT be all random but i cant imagine this is random.</p>

<p>Here are the yesterday's rolls where you can see the Round IDs too.</p>

<p>I saw the rolls a lot of time repeat sometimes but sometimes its not... I cant believe it doesnt have any math in it.</p>
