Dicas e Melhores Práticas
- Uses Math.random — appropriate for picking lottery numbers, rolling for game mechanics, choosing winners from a list, and other fairness uses.
- NOT cryptographically secure. Don't use this for password generation or security tokens — use the random-string-generator tool instead, which uses crypto.getRandomValues.
- With "no duplicates" enabled the tool uses a Fisher-Yates shuffle — distribution is uniform across the range.
- For dice rolls, the dice-roller tool gives you d4 / d6 / d8 / d10 / d12 / d20 with optional crypto-backed randomness.
- Results aren't logged anywhere; the page is stateless.
