About the Random Number Generator
Need a random number, a dice roll, a coin flip, or a lucky pick from a list? This all-in-one randomizer covers every everyday use case. Set a custom numeric range, roll any polyhedral die, flip a virtual coin, or paste in a list of names and let the tool pick one at random — all powered by a cryptographically seeded random generator.
From classroom activities to game nights, giveaway draws to statistical sampling, random number generation has dozens of practical applications. This tool keeps things simple: choose your mode, set your parameters, and click. Results are unbiased, instant, and reproducible on demand without any account or installation.

Frequently asked questions
Is the random number generator truly random?
The tool uses the browser's built-in random number API, which is suitable for games, decisions, and sampling. It is not designed for cryptographic key generation, but for everyday randomness it is more than sufficient and statistically unbiased.
Can I generate multiple random numbers at once?
Yes. In the Dice Roller mode you can specify rolling multiple dice simultaneously and see each individual result alongside the total. For bulk number lists, set your range and click generate repeatedly, or use the batch option if available.
How does the Lucky Picker work for giveaways?
Paste your list of participant names into the input — one name per line or separated by commas. Click 'Pick' and the tool selects one entry at random. Each pick is independent so there is no memory of previous draws.
Can I roll non-standard dice, like a d3 or d100?
Yes. Use the custom die mode and enter any number of sides you need. A d100 is useful for percentile rolls in tabletop RPGs, and a d3 can simulate a three-outcome event that standard dice cannot cover.
Is there a history of previous results?
Results from the current session are shown below the generator so you can review recent rolls or picks without re-entering settings. Closing or refreshing the page clears the history.
All randomization runs client-side in your browser — no inputs or results are ever sent to a server.
