SubSpace uses random numbers primarily in its encryption, generating [[prize]]s, and controlling [[door]]s.

The following code is used in generating the encrypted kestream, prizes, and doors:
<pre>
DWORD SS_RNG(DWORD seed)
{
DWORD nseed, temp;

temp = (MULT_C * (unsigned __int64)seed) >> 32;
temp = (temp >> 16) + (temp >> 31); //aka the sign bit

nseed = (seed % DIV_C) * 16807;
nseed -= (temp * 2836);
nseed += 123;

if (!nseed || nseed > 0x7FFFFFFF)
nseed += 0x7FFFFFFF;

return nseed;
}
</pre>
