Lottery numbers, raffle draws, test data, decision-making: random numbers come up surprisingly often. The ChrysoKit Random Number Generator covers all of those cases in one screen.
Why use it
We use cryptographic randomness rather than Math.random, support inclusive ranges, and let you generate hundreds of numbers at once with optional uniqueness.
How to use the Random Number Generator
- Enter the minimum and maximum values.
- Set how many numbers to generate.
- Toggle uniqueness if duplicates should be skipped.
- Press generate and copy the results.
Features worth knowing
Inclusive ranges
Min and max are both included in the possible values.
Bulk mode
Generate up to 10,000 numbers at once.
Unique mode
Skip duplicates for raffles and prize draws.
Pro tips
- For raffles, run the generator with unique mode and keep a screenshot of the result. It is the simplest fairness audit.
- If your range is huge but the count is small, leave unique mode off; collisions are unlikely.
- Cryptographic randomness is overkill for board games but free; we use it everywhere.
Privacy first. The Random Number Generator runs entirely in your browser. Nothing you enter is sent to a server.
Whenever you need a number drawn fairly, the Random Number Generator is the calmest path. Bookmark it once; it pays for itself fast.
