How to use it
Keep the team names on the wheel and spin once for each person in turn. Because every spin is independent, teams can come out slightly uneven — which is the honest behaviour for a random draw, and usually fine for four people across two teams.
If you need exactly equal teams, do it the other way round: put the people on the wheel, turn on “Remove the winner after each spin”, and deal them out in order — first spin to Team A, second to Team B, and so on.
Why captains picking is worse
Letting two captains pick alternately is the traditional method and the one that leaves someone standing last. A wheel has no opinion about who is good, which is the entire point in a classroom or a workshop where the teams are meant to be arbitrary.
When random teams are the wrong tool
Random assignment is right when the point is that nobody chose. It is wrong when the groups need balancing — mixed ability, mixed departments, keeping two people apart. Randomness will cheerfully put all the strongest players together, and a wheel cannot know that is a problem.
For those cases, draw the groups by hand and use the wheel only for the parts that genuinely should be arbitrary, like which team goes first.
More than four teams
The default is four, but the list is editable, so any number of teams works. For pairs, two entries. For a classroom split into six tables, six. The draw stays even regardless of how many slices there are.
Frequently asked questions
Will the teams be exactly equal?
Not if you spin per person — independent draws produce uneven groups sometimes. Use the deal-out method described above when equal sizes matter.
Can I use real team names?
Yes, replace the entries with anything: house names, colours, table numbers.
Can I stop two people ending up together?
Not automatically — the draw has no concept of who anyone is. Assign those two by hand first, then spin for everybody else.
What is the fastest way for a big group?
Put the people on the wheel rather than the teams, turn on "Remove the winner after each spin", and deal them out in rotation.
