Team maker online | split into even, random groups

Red-vs-white for a sports day, teams for board games or sports, groups for training and workshops, office shuffle lunches — the more you want to avoid stacking by skill or friendships, the better a random split fits.

Split by hand and people wonder, “Did you put them on the same team on purpose?” Assign at random and you're free of that second-guessing and those complaints.

1. Pick the number of teams — how many groups to split into. You can set anywhere from 2 to 10.

2. Enter the participants' names. Blanks are auto-numbered, so you can split by just setting the headcount.

3. Press “Split into teams” and everyone is shuffled and distributed evenly across the teams, then the result is revealed. Copy, share on X and LINE, and re-split are all one tap.

Participants are shuffled with the same deterministic randomness as an amidakuji ladder lottery, then dealt to each team in turn. Thanks to this dealing, team sizes differ by at most one person.

There's no room for a human hand in the assignment, and no one knows which team they're on until you split. So no one suspects “you rigged this grouping.”

Writing teams out on paper or calling names on the spot takes time, and can feel like the organizer's intent crept in.

Online, you just enter names and a count. Any number of people splits evenly in an instant, and the result shows on everyone's screen at once. Don't like it? Re-split right away.
