Questions fréquentes
Is it truly random?
Yes. It draws from your browser's crypto.getRandomValues, which is unbiased across the full range you set.
Can I generate more than one number without repeats?
Yes. Turn on "no repeats" to draw unique numbers until the range runs out, then it tells you it's exhausted.
Does it work with negative numbers or large ranges?
Yes. Any minimum and maximum are supported, including negative numbers, up to safe integer limits.

Flip a batch of 100 coins and you'll almost always see a streak of five or more somewhere in the run. That's not a broken randomizer — it's exactly what real randomness looks like. Here's the math behind streak length, and why 'it's due' is the wrong instinct.
- Why the standard 52-week savings challenge secretly punishes December

A lost d6 or a remote D&D session is the obvious reason to roll dice online. The less obvious reason: seeing the actual math of 2d6 vs. 1d20, and how a flat modifier changes your odds more than most players expect.
- Assigning fair raffle ticket numbers with a random number generator
Naming a winner by name feels arbitrary; drawing a number out of a known range feels provable. Here's when to reach for a numeric random draw instead of a name-list picker, with worked examples for raffles, lotteries, and sampling.
