About this tool
Splitting a group into fair teams is instant here. Paste your names with one per line, choose whether to divide by the number of teams or by players per team, and the Team Generator shuffles everyone into balanced groups. A reshuffle button gives you a fresh arrangement whenever you want one. It is handy for sports, classroom activities, board-game nights, and workplace breakouts. The shuffle relies on the browser's cryptographic random generator for genuinely even splits, and it all runs locally, so the names you enter never leave your device.
Frequently asked questions
How are teams kept balanced?
After randomly shuffling your list, the generator deals names out one at a time across the teams, like dealing cards. This round-robin approach keeps team sizes within one person of each other, even when the total does not divide evenly. If you choose a team size instead of a team count, it builds as many full groups as possible and places any leftover players into a final, smaller team.
Is the shuffle actually random?
Yes. The tool uses a Fisher-Yates shuffle driven by crypto.getRandomValues, the browser's cryptographically secure random source, rather than a predictable pattern. Every possible arrangement is equally likely, so no name is quietly nudged toward a particular team. Press the reshuffle button and you get an independent, equally fair arrangement, which is perfect when someone asks for a do-over.
Are the names I enter private?
Completely. All the shuffling and grouping happens in JavaScript inside your browser, so the names you paste are never uploaded to or saved on any server. They live only in the page while it is open and disappear when you close or reload the tab. That makes it safe to use the real names of students, employees, or friends without any privacy worries.
