Frequently Asked Questions
Is this truly random? +
Yes — this generator uses the Web Crypto API's crypto.getRandomValues(), which produces cryptographically secure random numbers. This is far more random than typical Math.random() functions and is suitable for security-sensitive applications.
Can I generate numbers without duplicates? +
Yes — in the Number List mode, tick the "No duplicates" checkbox and every number in your list will be unique. This is useful for lottery picks, random sampling, and raffle draws.
What dice types are available? +
You can roll D4, D6, D8, D10, D12, D20, and D100 dice. Roll up to 20 dice at once. This covers all standard tabletop RPG dice (Dungeons & Dragons, Pathfinder, etc.).
Can I use this to pick lottery numbers? +
Yes — the Lottery Picker has presets for UK Lotto, Powerball, EuroMillions, and classic 6/49. You can also customise the number of picks, range, and bonus balls to match any lottery worldwide. Note: random numbers have exactly the same odds as any other combination — all lottery combinations are equally likely.
