Random Number Generator is a free online tool that generates random numbers within a specified range.
We use the browser's crypto.getRandomValues API to generate cryptographically secure random numbers, which is sufficiently random for general purposes.
Yes, set the range and quantity with no duplicates for lottery-style draws. For example, generate 6 numbers from 1-45 without duplicates.
Recording the moment of the draw on screen and publishing the participant list and the range beforehand is the most convincing approach. Fixing the rule in advance — "numbers 1 to 132, three winners" — removes any suspicion that the conditions changed once the result was known. For a draw with a substantial prize, running it in front of several witnesses, or letting one of the participants press the button, earns trust far more effectively than any claim about the algorithm.
That is normal. Each draw starts fresh, so the previous result has no influence on the next one, and in a range of 1 to 10 a repeat has a one-in-ten chance — hardly rare. A sequence with no repeats at all is in fact the less natural outcome for true randomness. If you need each value to appear only once, turn on the no-duplicates option; with it on, you cannot draw more numbers than the range contains.
