Tap the card or press Generate — cryptographically secure
This page generates a uniform random integer in the range 1–1000 inclusive using crypto.getRandomValues(), the browser's cryptographically secure random source. Each of the __NUM_WORD__ numbers has exactly a 1/1000 probability of being drawn. Rejection sampling eliminates modulo bias, so every number is equally likely — no number is ever slightly over- or under-represented.
Use 1–1000 for large giveaways, sweepstakes with thousands of entries, employee number selection, ID generation, and statistical sampling. Each of the 1,000 integers has exactly 0.1% probability — uniformly distributed.
