Random Number Generator

Looking for a hassle‑free way to generate a single number or a batch of unique randoms? Our Random Number Generator is built for speed, flexibility, and ease—no sign‑ups, no popups, just pure randomness.

Whether you're running a classroom raffle, drawing dice rolls, picking lottery numbers, or just spinning up a lottery-style pick, this tool gives you full control: set range (minimum and maximum), quantity, and toggle duplicates on or off.

With support for ranges like 1‑100, decimal outputs, or large batches of numbers, it's perfect for both casual use and more structured tasks like statistical sampling or gaming utilities.

🧠 Key Features & Customization Options

Here's what makes our random number tool stand out:

• Range flexibility: Set your own min/max values (e.g., 0–100, 1–50, or even 1000+).
• Quantity selector: Generate one number or any quantity you need.
• Unique output: Avoid repetition with "unique numbers" toggle—ideal for drawing without duplicate picks.
• Integer or decimal: Pick whole numbers or decimals—great for stats or probability exercises.
• Copy to clipboard: Output appears instantly with a one-click copy button.

These options make it a top choice among random number generators, number pickers, and rng tools.

🎲 Common Use Cases & Practical Examples

Whether you're teaching, gaming, or testing, you'll find this tool invaluable:

• Classroom raffles & prizes: Draw student names or numbers without bias.
• Bingo and lotteries: Generate random draws for 1–75 or 1–90 bingoes or standard 6/49 numbers.
• Role‑playing games: Roll D20s, D6s, or custom dice ranges with ease.
• Statistical samples: Quick random picks for surveys or sampling tasks.
• Testing and QA: Create unique IDs, test data, or randomized inputs for software tests.

No need to manually shuffle numbers—this is your go-to random number generator 1‑100, number randomizer, or lottery pick tool.

🔎 How It Works Behind the Scenes

The generator uses JavaScript's built‑in Math.random(), scaled to your range. It then:

• Generates numbers proportionally across the range
• Rounds to integer or retains decimal
• Checks for duplicates if "unique only" is enabled
• Stops at requested count

This ensures results are **fair**, **unbiased**, and **appropriately random**—ideal for legitimate random draws or simulations.

💡 Tips & Best Practices

• For lottery-style results like 6/49, set range to 1–49 and enable unique numbers.
• Need decimal samples for data? Deselect integer-only mode.
• Generating 100+ unique numbers? Ensure your range is large enough to avoid conflicts.
• Want more sequential picks? Combine this with the Number Sequence Generator tool.
