How the Random Decimal Generator works
Where the randomness comes from
Each request draws from an entropy pool that mixes the operating system's cryptographically secure generator with high-resolution timer jitter, then expands it through an HMAC-DRBG. Ranges use rejection sampling, so no value is favoured.
Checked on every draw
The JEV fairness engine runs chi-square, runs, serial-correlation and Kolmogorov–Smirnov tests on each result and scores it from 0 to 100. If a result fails at a strict threshold, it is redrawn from fresh entropy.
Private by design
Results are generated on our server and stored only in your own history. Lists you paste are never shared or used for anything else.
