What skill scale should I use for balanced teams?

Any scale works, because players are only compared to each other. Use 1 to 10, ELO, rank points, MMR or hours played, but keep one scale across the whole list.

Can I force two players onto the same team?

Yes. Write Alice + Bob in the rules. Chains work too, so Alice + Bob and Bob + Carol puts all three together. Use Carol - Dan to keep two players apart.

Can I swap players after the teams are generated?

Yes. Click one player and then another and they swap, across any two teams or with the substitutes. Team totals update immediately.

How does the team balancing work?

Players locked together are merged into one unit, units are sorted strongest first and assigned to the weakest team with room, then the tool repeatedly swaps pairs between teams to bring the totals closer, always respecting captains, keep-together and keep-apart rules.

Is the player list uploaded anywhere?

No. The list, the rules and the split all stay in the browser. Only the optional forum topic import contacts the server.

Q: Do I have to give every player a skill rating?

No. Players without a rating are given the average of the players who have one, so you can rate only the people you know. If nobody has a rating you get a plain random split with even team sizes.

Team Splitter

Nobody complains that teams were not random enough — they complain that the teams were stacked. Give people a skill rating and this builds sides that actually match.

Players one per line — add a skill number after the name if you want balanced teams

Write Alice 9 or Alice (9). Skill can be any scale you like — 1–10, rank points, hours played. Players without a number get the average of the rest.

How to split

Split by

Teams

Seed

Same players + same seed = same teams

Captains, duos and people who should not play together

Captains — one per team, spread automatically

Rules
Alice + Bob puts them on the same team. Carol - Dan keeps them apart. One rule per line.

Team names — optional, one per line

Leftover players sit out as substitutes instead of making teams uneven

Copied

Add a skill number

Write Alice 9. Any scale works — 1 to 10, rank points, hours played. Without numbers you only get teams that are even in size.

Set the rules

Captains one per team, duos who always play together, people who should be kept apart. The splitter works around all of them.

Adjust and share

Click two players to swap them by hand, then copy the teams straight into Discord.

Even teams are not the same as fair teams

Most team generators shuffle a list and deal it out like cards. You get five players against five players, and one side has the three best in the lobby. Nobody ever complained that teams were not random enough — they complain that the game was over in ten minutes.

Give this one a skill number per player and it stops dealing and starts balancing. On a ten-player list where the gap between sides averages 5.4 points with a plain shuffle, balancing brings it down to 1.0 — which on an odd total is as close as it is mathematically possible to get.

What the numbers can be

Whatever you already have. The splitter only cares about relative size, not the scale:

A gut-feeling 1 to 10, agreed in the Discord before the scrim
In-game rank converted to a number — Silver 1, Gold 8, Global 18
Faceit level, ELO, MMR, or rating from your own stats page
K/D ratio, hours played, or wins this season

Players without a number are given the average of everyone who has one, so a half-filled list still works. Leave the numbers out entirely and you get a clean random split with even team sizes.

Rules you can set

You write	What happens
`Alice 9`	Alice has skill 9
`Alice (9)`	Same thing, if the brackets read better to you
`Alice + Bob`	Always on the same team — duos, friends, a player and their mic
`Carol - Dan`	Never on the same team
Captains field	One captain per team, spread automatically
Team names field	Real names instead of Team 1 and Team 2

Spaces around the + and - matter, so a player called Jean-Luc does not get read as a rule.

How the balancing actually works

Players who must stay together are merged into a single unit with their combined skill, so the rest of the maths cannot split them.
Units are sorted strongest first and each one goes to the team that is currently weakest and still has room — the standard greedy pass.
Then the splitter keeps looking for a pair of players it could swap between two teams to bring the totals closer, and does it, until no swap improves anything.
Every step checks the rules: nobody who must be kept apart ends up together, captains stay one per team, team sizes stay as equal as possible.
Ties are broken with a seeded shuffle, so equally good splits still vary between runs — and the same seed always gives the same teams.

If a rule genuinely cannot be satisfied — three people locked together but teams of two — the tool says so instead of quietly ignoring it.

Uneven numbers

Eleven players and two teams gives you six against five. If you would rather keep the sides equal, tick the substitutes option and the extra players sit out — the weakest ones, so the match itself stays balanced. Captains are never picked as substitutes.

Community tournaments where teams are drawn on the spot
LAN parties and Discord game nights
Splitting a class, a team at work, or anything else into fair groups

Questions

Do I have to give everyone a skill number?

No. Anyone without one is given the average of the players who have one, so you can rate only the people you know. If nobody has a number, you get a plain random split with even team sizes — which is exactly what most other tools do.

What scale should I use?

Any. The splitter compares players to each other, so 1–10, ELO, rank points or hours played all work the same way. Just keep one scale across the whole list — mixing 1–10 with four-digit ELO will make the ELO players look infinitely better.

Can I force two friends onto the same team?

Yes. Open the options and write Alice + Bob. Chains work too — Alice + Bob and Bob + Carol puts all three together. The balancing then treats them as one block with their combined skill.

The teams still look off. Can I change them?

Click one player, then click another, and they swap. It works between any two teams and with the substitutes. The totals update as you go, so you can see what your change did to the balance.

Will I get the same teams twice?

Only if you want to. The seed is shown after every split — same players and same seed always produce the same teams, which is useful if somebody claims you re-rolled until you liked the result. Press the dice, or Shuffle again, for a different split.

Can I pull the players from a forum topic?

Yes, if you are signed in. Paste the link to your sign-up topic and everyone who replied is added, once each. The person who started the topic is left out. You can then add skill numbers next to the names.

Is anything sent to a server?

No. The list, the rules and the split all stay in your browser. The only request that leaves the page is the forum topic import, and that only asks for the names of people who replied to a topic you can already see.
