How It Works
The range 1–10 is small enough that any mapping shortcut could visibly bias results, so the same
rejection-sampling engine as the full generator is used: a secure 32-bit value is drawn with
crypto.getRandomValues(), and values outside the exact multiple of ten are discarded.
Each of the ten outcomes has probability 1/10 with no rounding shortcuts.
Unique mode samples without replacement, so requesting ten numbers returns a random permutation of the whole range. Everything runs locally, and the local history can be cleared whenever you like.
Examples
- Finger game replacement: get a fair value from 1 to 10 when two people would normally count fingers.
- Random rating: generate a 1–10 score for role-play or demo data.
- Full permutation: quantity 10 with unique mode → all ten values in random order.
- Practice problems: generate several values and ask students to multiply or round them.
Common Uses
- Quick classroom picks and question ordering.
- Choosing an option from ten labeled choices.
- Generating 1–10 ratings for samples, tests and demos.
- Creating short random sequences for games and exercises.
Frequently Asked Questions
Why lock the range to 1 to 10?
The 1–10 range covers the most repetitive everyday requests — ratings, quick picks and finger-game replacements. Locking the inputs keeps the page to a single tap. For any other range, use the full Random Number Generator.
Can the result be 1 or 10?
Yes. Both endpoints are inclusive and equally likely, just like every value between them.
Can I use it instead of a ten-sided die?
Yes for informal use. For tabletop games that need standard dice with notation and roll history, the Dice Roller is the better fit; it includes a D10 and custom dice.
Can I generate ten unique numbers from 1 to 10?
Yes — that produces a random permutation of 1 through 10. Enable Unique numbers in Advanced Options and set the quantity to 10.
How is fairness guaranteed?
Values come from crypto.getRandomValues() with rejection sampling for unbiased results. Each of the ten values has exactly a 10% chance on every draw.
