About This Random Number Generator

This tool draws from JavaScript's Math.random(), producing pseudo-random numbers — values that appear statistically random and are drawn with equal probability from anywhere in your chosen range. That makes it well suited for games, raffles, sampling, and everyday decisions, but it is not a cryptographically secure source, so don't rely on it for passwords, PINs, or anything security-sensitive.

Whether duplicates matter depends on what you're generating: a lottery-style draw or a list of distinct winners needs the Unique Set mode so nobody is picked twice, while dice rolls, coin flips, or repeated samples should allow duplicates, since rolling the same number twice in a row is a normal, expected outcome.

🎟️

Raffle Picker

Draw one or several unique winning numbers from a pool of entries without any repeats.

🎲

Dice Roller

Simulate any die — d6, d20, d100 — by setting the range to match its faces and allowing duplicates.

📋

Sample Selector

Pull a random subset of row numbers or IDs from a spreadsheet or list for quick statistical sampling.

🔐

PIN/Password Practice

Generate a numeric digit sequence for mockups or testing — not for real, security-sensitive credentials.
