RANDOM TOOL
Random Number Generator
Set any safe whole-number range, choose how many results you want, and optionally prevent repeats. Draws use the browser Web Crypto API and happen on your device.
HOW TO USE IT
Simple jobs, done fast.
Enter the smallest and largest whole numbers you want to include, choose how many results to draw, then run the generator. Turn on no-repeat mode when every result must be unique.

PRACTICAL TIPS
- Use no-repeat mode for classroom numbers or unique winners.
- Double-check the range before a group draw so everyone knows the same rules.
- For quick testing, generate several sample integers in one run.
How randomness works: Tossora uses the browser's Web Crypto API to generate random values on your device. That is stronger than Math.random(), but Tossora is still designed for everyday decisions, games, classrooms, and learning—not regulated drawings, gambling, or security-critical decisions.
QUICK ANSWERS
Random Number Generator FAQ
Can I generate multiple random numbers without repeats?
Yes. Choose how many results you want and enable no-repeat mode. Each number in that draw will be unique as long as the requested count fits inside the selected range.
Can the same number appear twice?
Yes, unless you enable no-repeat mode. With no-repeat enabled, each result in that draw is unique.
Are the minimum and maximum included?
Yes. Both endpoints are eligible, so a range of 1 to 10 can return 1, 10, or any whole number between them.
