❓ Frequently Asked Questions
Can I generate unique random numbers?
Yes. Disable the “Allow Duplicates” option to ensure each number is unique. The generator keeps track of numbers that have already been used and stops when the range is exhausted.
Is the random number generation secure?
All numbers are generated in your browser using cryptographically secure randomness when available. Nothing is sent to our servers, so your results remain private.
What presets should I use?
Use the dice preset for quick 1-6 rolls, lottery for 6 unique numbers between 1-49, and “10 Unique” for quick unique data samples. You can still tweak the range and count afterwards.
