Random team generator

How to use it

Type or paste your guest list into the box — one player per line. Set the team count, hit Generate teams, and copy the result into your invite, scoresheet, or message thread. The shuffle is random each click, so if a particular split feels off, just generate again.

Why it's done client-side

Quiz night guest lists are personal data. We didn't want yours sitting on a server we don't need to host. The whole tool runs in the browser tab — there's no network call once the page has loaded, and we don't log or store anything. The shuffle is Fisher–Yates, which produces uniformly random orderings; the round-robin into team buckets keeps team sizes within one of each other, so "balanced" is genuinely balanced.

Tips for balanced teams

• Knowledge-spread is a manual call. If you know one person is a sports trivia ringer, drop them in last so the algorithm doesn't accidentally pile all your domain experts into one team.
• Six or seven players per team is the sweet spot for a casual quiz night — large enough that everyone contributes, small enough that the team can actually agree on an answer before the timer runs out.
• For corporate or team-building quizzes, mix departments — the win condition is connection, not the quiz score.
• For school or family events, mix age groups inside each team. The general-knowledge round becomes interesting when grandparents and grandkids are on the same side.
• If you have a single ringer, consider asking them to host. Real experts often enjoy reading questions out as much as answering them, and the room ends up more even.

How many teams should you have?

The math is straightforward once you know your guest count and the format you're running. For a casual evening with 20–30 guests, four to five teams of five works well — the room stays manageable, scoring is fast between rounds, and prize chunks divide cleanly. For 40–60 guests at a venue, six to eight teams of seven gives the right energy. Past 80 guests, you're running a "pub quiz" rather than a "trivia night", and you'll want pre-assigned table numbers and printed team folders.

If you're hosting a small group of 8–12, the dynamic changes — two teams of four to six is plenty, and the social side of the event becomes louder than the competitive side. That's the right call for an intimate dinner-party quiz.

What "balanced" means here

This generator balances on team size — every team ends up within one player of every other. If you paste 22 names and ask for 4 teams, you'll get two teams of 6 and two of 5; the algorithm round-robins through the shuffled list so no team is ever short by more than one player. That's all it does. The generator does not balance on knowledge, age, gender, or any social factor — it doesn't know any of those things. If those balances matter, do an initial shuffle here, then move one or two names manually before reading the teams out.

Some quiz hosts swear by an opening-round handicap instead: let teams self-form, then weight the first round's score by team size. That keeps the social pleasure of choosing your own team intact and removes the size advantage. If that fits your event better, this generator becomes optional.

Why not use a spreadsheet?

You absolutely can — Excel's RAND() and Google Sheets' RANDBETWEEN() both do this. The reason we built a dedicated page is friction: clicking a button on a website is much faster than typing the formula, copy-pasting names into rows, dragging a fill handle, and then sort-by-random. For a one-shot generation right before an event, fast wins. For a recurring weekly quiz where you want to track team-pair history and avoid repeat pairings, the spreadsheet wins.

Pair it with the rest of the host's kit

Once teams are set, run the round timer on a projector for the night, keep the tiebreaker library open for the inevitable draw, and print the host kit PDF for scoresheets and a master scoring grid. Full strategy: the quiz night hosting guide.
