How to use it
- Set the minimum and maximum (1–100 by default) and how many numbers you want (1–100), then press Generate. The numbers roll like a slot machine and lock in one by one.
- Turn off Allow duplicates to make every number unique. If you ask for more unique numbers than the range holds, you will see a notice.
- In Exclude numbers, type values separated by commas, like
4, 13, or a range like20~25. Those numbers will never be picked. - Copy the result with one click. The last 10 results are listed below (they clear when you reload the page).

How are the numbers generated?
Numbers come from your browser's cryptographic random number generator (crypto.getRandomValues). The tool also removes modulo bias, a small skew that can make some values come up slightly more often, so every number in the range is equally likely. Everything runs on your device; nothing is sent to a server.
It handles whole numbers from -1,000,000,000 to 1,000,000,000. For lottery-style picks, the Lotto Number Generator is a better fit, and the Spin the Wheel works well for names or menu choices. For anything security-related, use the Password Generator.
