Are the random results unbiased?

The generator uses rejection sampling to avoid modulo bias when picking integers.

Can I paste a long list of names?

Yes. Put one entry per line and the picker will ignore blank lines.

Does the group generator include everyone exactly once?

Yes. It shuffles the list and distributes entries across groups without duplicates.

Is this suitable for cryptographic security?

About this tool

Random tools are useful for quick decisions, classroom activities, giveaways, and lightweight planning. This page includes a random number generator, a name wheel picker, and a group generator that distributes entries across a chosen number of groups.

The random number generator produces an integer within your bounds. The name wheel selects a single entry from your list. The group generator shuffles your entries and assigns them to groups in a simple, fair round‑robin distribution.

Where available, randomness is generated from the browser’s cryptographic random source. This helps avoid predictability compared with basic pseudo‑random sequences. For casual use cases, it’s a sensible default.

If you want to share results, you can copy the output directly. For repeat use, keep a list of names in a note and paste it here when needed.

For time-based classroom workflows, pair these tools with the classroom and exam timers from the navigation.
