In Limbo, each game outcome is generated transparently using a combination of a server seed, a client seed, and a nonce. These values are hashed together with SHA-256 to produce a random float, which, when adjusted by the house edge, determines the final crash point. This process lets players independently verify that each result is fair and unpredictable.<pre data-language="plain">function getRandomFloatFromSeed($serverSeed, $clientSeed, $nonce) {
 // Create combined string and hash it
 $combined = "{$serverSeed}:{$clientSeed}:{$nonce}";
 $hash = hash('sha256', $combined);
 
<pre><code>// Use the first 8 hex digits (32 bits)
$num = hexdec(substr($hash, 0, 8));

// Normalize to (0, 1]; fallback to a very small number to avoid zero
$result = $num / 0xffffffff;
return $result ?: 1e-8;
</code></pre>
}
function generateLimboResult($serverSeed, $clientSeed, $nonce) {
 // Calculate house edge multiplier from config
 $houseEdge = (100 - 1) / 100;
<pre><code>// Get random float from seed
$float = getRandomFloatFromSeed($serverSeed, $clientSeed, $nonce);

// Inverse transform with the house edge
$rawValue = $houseEdge / $float;

// Round down to two decimals
$crashPoint = floor($rawValue * 100) / 100;

// Ensure the result is never below 1
return max($crashPoint, 1);
</code></pre>
}
