Random Number / Dice Generator

What this tool does

The Random Number / Dice Generator produces random numbers within a range or simulates dice rolls with a visual display. It is designed for quick, repeatable randomness in small tasks like raffles, test data generation, or tabletop sessions. Results are shown immediately and can be copied for reuse.

When to use this tool

Use it when you need a fast random pick without setting up a spreadsheet or script. It is useful for selecting winners, deciding order, or generating sample IDs. If you need secure credentials instead of simple randomness, use Password Generator and verify entropy in Password Strength.

How it works

The tool uses your browser's random number generator to produce values in the range you set. For dice rolls, it picks a value between 1 and the selected number of sides for each die and totals the result. All calculations happen locally and update the UI with each spin or roll.

Example use case

You are running a small giveaway and need three random winners from a numbered list. Set the range to match your list, set the count to three, and spin. Copy the results and match them to your list entries.

Use cases

• Pick winners for a small raffle or giveaway.
• Roll dice for tabletop sessions.
• Generate random IDs for mock data.

Notes & limitations

This tool is intended for casual randomness, not cryptographic security. Results should not be used for security-sensitive workflows or gambling. For larger sample sets, consider exporting data from a dedicated tool.

If you need repeatable results for testing, record the outputs rather than relying on a fresh roll each time. The browser's random generator is suitable for everyday use, but it does not provide a fixed seed option or audit trail. Document your selection process if fairness needs to be verified later.

For dice games with special rules, roll once per rule step to keep outcomes transparent.
