Picking a giveaway winner, assigning teams, rolling initiative in a tabletop game, sampling rows from a dataset — all of these need numbers free of human bias. People asked to 'pick a random number' gravitate to 7 and 37 and avoid round numbers; real randomness requires an algorithm.
This generator produces uniformly distributed random integers in any range you choose, with options for multiple draws and duplicate-free results — ideal for raffles where each entry may win only once.
How to Use This Tool
- Set the minimum and maximum of your range (both inclusive).
- Choose how many numbers to draw.
- Toggle 'unique' if duplicates should be excluded (lottery-style).
- Click generate and copy the results.
Frequently Asked Questions
Is this true randomness or pseudo-randomness?
Browser randomness is pseudo-random — generated by an algorithm seeded with unpredictable system entropy. For games, raffles, and sampling it is indistinguishable from true randomness; only cryptographic key generation demands stronger guarantees, which the Web Crypto API provides.
Are all numbers in the range equally likely?
Yes. The generator uses an unbiased mapping from the random source to your range, so a range of 1–100 gives each integer exactly a 1% chance. Over many draws you will still see streaks and repeats — that is what genuine randomness looks like.
How do I run a fair giveaway with this?
Number your entries 1 to N in a fixed, published order (for example, comment order). Generate one unique number per prize. Because results are uniformly distributed, every entry has an equal chance, and screenshots of the draw make the process auditable.
