Random number generator

Draw one or more whole numbers between your chosen lower and upper bounds. Decide whether numbers may repeat. Both endpoints are included.

Whole number from −1,000,000,000 to 1,000,000,000.

The upper bound is included.

From 1 to 1,000 numbers.

No repeats means each result is distinct within this draw.

Bounds: -1,000,000,000 to 1,000,000,000. Up to 1,000 numbers per draw.

Results

How to draw random numbers

Enter the smallest and largest whole numbers, choose how many results you need, and select whether repeats are allowed. Then select Generate numbers. For example, a single draw from 1 to 6 works like a digital die: both 1 and 6 can appear. Draw three without repeats from the same range and all three will differ.

  • Bounds can range from −1,000,000,000 to 1,000,000,000; draw 1–1,000 numbers at a time.
  • If a range holds only three integers, you can draw at most three without repeats.
  • Copy numbers puts the displayed results on separate lines on your clipboard.

Method and limits

Your browser provides cryptographic random bytes. The generator rejects some resulting 32-bit values that would otherwise make certain integers slightly more likely after division. For a draw without repeats, it picks each number from the remaining choices. The output is digital, not a physical draw or a certified random process. If secure browser randomness is unavailable, the tool shows an error instead of a result.

Results stay in this tab and are not sent to the server. Editing an input clears the previous draw so it cannot be mistaken for a new one. For formal lotteries, check the applicable rules and evidence requirements yourself.

Questions and answers

Are the lower and upper bounds included?
Yes. With 1 as the lower bound and 6 as the upper bound, a result can be 1, 2, 3, 4, 5 or 6.
Can a number appear more than once?
Yes, if you choose Repeats allowed. With No repeats, each number appears at most once per draw. The requested count cannot exceed the number of integers in the range.
How random are the results?
The tool uses cryptographic random bytes supplied by your browser and a method that avoids modulo bias. This is digital output, not a physical or certified draw for lotteries, audits or security decisions.
Are my numbers stored?
No. Your settings and results stay in this open browser tab. They are not sent to Spirelight and disappear if you reload or close the page. Copy them if you want to save them yourself.
