How do I pick a random winner for a giveaway?

Go to the List tab and enter all entrants' names or ticket numbers, one per line. Select Pick N and enter the number of winners you want. Click Generate — winners are selected at random with no repeats. Copy the result and share it publicly as proof of a fair draw.

Is my data saved or sent anywhere?

No. All calculations happen exclusively in your browser using client-side JavaScript. The lists, numbers, and results you enter are never transmitted to any server and are never stored or logged. Your privacy is fully protected.

Can I use this on my phone?

Yes. The generator is fully optimized for mobile and works on any iPhone or Android device in any modern browser. No app download required.

How do I roll dice online?

Click the Dice tab. Choose the number of dice (1–6) and the type (D4, D6, D8, D10, D12 or D20), then click Generate. The total is calculated automatically when you roll multiple dice — great for D&D, Pathfinder, and other tabletop games.

What is a random number generator?

A random number generator (RNG) is a tool that produces numbers with no discernible pattern or predictability. Random numbers are used everywhere — from classroom decisions and tabletop RPGs to raffles, statistical sampling, and software testing.

There are two main types of generator:

True random number generators (TRNG): these use unpredictable physical phenomena — atmospheric noise, radioactive decay — as a source of entropy. The output is fundamentally unpredictable in a physical sense.
Pseudorandom number generators (PRNG): these use mathematical algorithms seeded with an initial value. Fast and sufficient for the vast majority of everyday uses, but theoretically reproducible if the seed is known.

Our tool uses your browser's crypto.getRandomValues() API — the same cryptographically secure source used for HTTPS encryption and secure token generation. Results are fully trustworthy for prize draws, games, sampling, and any situation that demands genuine impartiality. All computation happens client-side: your numbers never leave your device.

How to use the random number generator

The tool is designed to be instant and zero-friction:

Set the range: enter your desired minimum and maximum. By default the generator draws a number between 1 and 100.
Choose the quantity: need just one number, or several at once? Enter how many in the Quantity field.
Allow or disallow duplicates: for a draw where each entry can only win once — like a raffle — untick Allow duplicates.
Click Generate: your number appears instantly — no loading screens, no waiting.
Copy or regenerate: copy the result to your clipboard with one click, or hit Generate Again for a fresh draw.

The other tabs offer a dice roller (D4 to D20), coin flip, and a list tool for shuffling or picking random winners from a custom list.

What can you use a random number generator for?

Far more useful than it first appears, a random number generator solves dozens of everyday situations.

Giveaways and social media contests

Instagram and TikTok giveaways are hugely popular in the US. Paste all entrant names (from comment sections, DMs, or a spreadsheet) into the List tab, choose Pick N, and click Generate — the result is instant, transparent, and screenshot-ready to share as proof.

Classroom and education

Teachers use random generators to call on students, form teams, assign presentation slots, or decide the order of class activities without any appearance of favoritism. The List tab handles any number of student names, picking each one only once when duplicates are disabled.

Tabletop RPGs and board games

No dice nearby? The Dice tab covers D4, D6, D8, D10, D12 and D20 — the complete set for Dungeons & Dragons, Pathfinder, or any board game. Roll up to six dice simultaneously with the sum automatically calculated.

Raffle and prize draw drawings

PTA fundraisers, church raffles, company holiday parties — any event with a raffle needs a provably fair draw. Enter ticket numbers or names in the List tab, pick a winner, and share the screen or screenshot for full transparency.

Decision making and coin flips

Can't decide between options? The Coin tab gives an instant heads-or-tails flip. The Number tab works great for picking between any number of choices — set Max to the number of options and let chance decide.

Statistics and sampling

Students, researchers, and data analysts use random number generators to create random samples, run simulations, seed random processes, and generate test data. Our crypto.getRandomValues() implementation meets cryptographic-grade standards for these applications.

In the Number tab, set Min to 1 and Max to 10, then click Generate. You'll get a random integer between 1 and 10 inclusive, instantly. Adjust the range to whatever you need.
