Random Number Generator Without Repeats
Sample an integer range without replacement: this page starts with ten distinct values from 1 to 100 and waits for your draw. Every value can occur at most once in the current batch. Set another inclusive range, choose a visible quantity up to 1,000, and optionally sort the selected values. This is a generic numeric draw; it does not track past batches, accept a sparse list or implement lottery predictions.
Drawn without repeats · 1 to 100

Standard notation: 2d6, d20, 3d6+2.
Common questions
- How does no repeats differ from independent draws?
- Sampling without replacement prevents duplicates within this batch. Independent draws can repeat a value. Future batches are fresh and may contain values that appeared before; no history blacklist is maintained.
- What if the range is smaller than the requested count?
- The tool refuses the draw and names the range size. Widen the endpoints or choose a smaller count. It does not return a shorter list silently.
- Does sorting make the selection less random?
- It changes the display order after sampling. The selected set is unchanged. Leave Sorted off when you need the drawn order; turn it on for an easier-to-scan numeric list.
- How do I export the result?
- Copy all copies the actual integers separated by a comma and space. This page does not export a file or a certified draw record.
Whole integers use the browser’s cryptographic random source and rejection sampling within safe-integer bounds. No repeats applies within one batch. Decimal output, user seeds and external randomness sources are not implemented.
