H1_Random Number Generator - No Repeats, Sorted | MultiTool

How it works

Set the minimum and maximum, choose how many numbers (up to 1000) and toggle no-repeats and sorting. Perfect for draws, testing and learning probability.

Randomness, pseudo-randomness and fairness

Browser random number generators are pseudo-random: they start from an unpredictable seed (timings, entropy from your machine) and produce a sequence that is statistically indistinguishable from random. For draws, games, sampling and giveaways, that is exactly what you want — every number has the same chance, and no pattern a human could exploit.

• No-repeats mode draws without replacement (a Fisher–Yates style shuffle), just like pulling numbered balls from a bag — perfect for raffles and bingo-style draws.
• With repeats simulates true dice-and-coins behavior — ideal for games, simulations and probability exercises.
• Cryptography is different: generating passwords, keys or tokens requires cryptographic randomness — that is what our Password Generator uses internally.

A note on fairness for public draws: because the numbers are generated on each participant's own device, the result is auditable only by trust. For high-stakes public raffles, record your screen or use the wheel-style draw with visible participants.
