Random tools
Generate random numbers, pick a winner from a list, or split people into groups.
Random number generator
Pick a random integer between two bounds.
Name wheel
Enter names (one per line), then spin.
Group generator
Randomly split a list into groups.
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.
FAQ
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? - These tools are intended for everyday decisions, not security-sensitive use.
