When is this useful?

  • Raffles and giveawaysGenerate a random ticket number, or pick one winning number from a range of entries.
  • Games and decision-makingRoll a custom-range "die," settle a decision, or randomly assign turn order.
  • Sampling and testingPick a random sample of IDs or record numbers from a known range, without duplicates, for spot-checking or testing.
03

Examples

  • A single random numberMin 1, Max 100, Count 1, duplicates allowed: generates one random number between 1 and 100.
  • A raffle draw with no repeatsMin 1, Max 200, Count 3, duplicates off: generates 3 different winning ticket numbers, guaranteed not to repeat.
  • Rolling a set of diceMin 1, Max 6, Count 5, duplicates allowed: simulates rolling five 6-sided dice at once.
04

How the numbers are generated

Each number is chosen uniformly at random from your min–max range (inclusive) using the browser's built-in random number source. When duplicates are not allowed, the tool shuffles the full range and takes the first "count" values, guaranteeing every result is unique.

05

Inputs, outputs, and assumptions

Minimum, maximum, and count must all be whole numbers, with minimum less than or equal to maximum. When duplicates are turned off, "how many numbers" cannot exceed the total size of the range (for example, you cannot pick 10 unique numbers from a range of only 5 possible values).

06

Is this cryptographically secure?

No. This tool uses standard, fast, browser-based randomness suited for games, raffles, sampling, and everyday decisions. It is not intended for cryptographic key generation, security tokens, or gambling systems that require certified randomness.

07

Privacy and local processing

The generation runs entirely in your browser. Nothing you enter or generate is uploaded, stored, or shared, and closing the tab clears everything.

08

Frequently asked questions

Can I generate numbers without repeats?

Yes. Turn off "Allow duplicate numbers," and every generated number will be unique. The count you request cannot exceed the number of possible values in your range.

What range of numbers can I use?

Any whole-number range, as long as the minimum is less than or equal to the maximum. There is no fixed upper limit.

Is this suitable for a real raffle or giveaway?

Yes, for casual raffles and giveaways this works well. For a legally regulated drawing, check your local requirements, since some jurisdictions require a certified random-number process.

Why does every click give a different result?

Each click generates a brand-new random draw. Nothing is remembered between clicks, so results are not repeatable or predictable.

Is my data saved?

No. Everything happens in your browser; nothing is sent to a server.
