How to break a tie fairly

Two kids both want the front seat. A club vote comes out 6–6. Your fantasy league draft has two people claiming the first pick. Board game night ends with a tie on points and nobody reads the tiebreak rule because the box is already back on the shelf.

Ties feel tiny, but they're where people decide whether a process was fair. Settle one badly and someone sulks for a week. Settle it well and nobody remembers it by dessert.

Here's how I'd think about it, starting with the question most people skip.

First: should this be decided by chance at all?

Chance is the right tool when both outcomes are acceptable and nobody has a stronger claim. Who picks the movie. Who serves first. Which of two equally good restaurants. A random pick is quick, nobody's ego gets involved, and the loser can blame the coin instead of you.

Chance is the wrong tool when one side has a better claim that you just haven't looked at yet. Two siblings fighting over the front seat? If one of them gets carsick, that's not a tie. A club vote tied 6–6 on spending the budget? Most clubs have a rule for that in their constitution, often the chair's casting vote or a re-vote after discussion. Use the rule first. Flip a coin only if the rule tells you to, or if there isn't one and both sides agree.

A quick test: if the loser would have a real reason to say "but that's not fair," find the reason first.

Two-way ties: the coin toss, done properly

For two people or two options, a coin toss is the classic. It's fast and everyone understands it. A few habits make it hard to argue with.

Call before the flip, not while it's in the air. Agree who calls and what they called. "Sam calls heads" said out loud, before anything moves.

Decide what happens on a drop. Coins roll under sofas. "If it falls on the floor, we flip again" saves a debate.

Agree on one flip or best of three, before the first flip. Switching to best of three after you've lost is the most common cheat in the history of siblings.

Let the other person flip. Or flip it onto the table where both of you can see.

If there's no coin around, the yes or no wheel has a Heads / Tails mode: tap it and press SPIN. It's the same 50/50 as a fair coin, with no coin to lose. It's handy on video calls, where one person flipping a real coin off-camera doesn't convince anybody. Share your screen and spin.

Real coins are very close to fair but not perfect. A 2023 study by František Bartoš and colleagues ("Fair coins tend to land on the same side they started") recorded 350,757 hand-tossed flips and found coins landed on the side they started on about 50.8% of the time. That's a tiny bias and nothing to worry about at the dinner table, but it's a fun fact to have when someone insists their flip was rigged.

Turning a tie into a yes-or-no question

Some ties are two options dressed up as an argument: "Pizza or tacos?" The cleanest way to spin for it is to name one option Yes and the other No out loud, before the spin. "Yes is pizza, No is tacos." Then spin. No relabeling afterwards.

If you're genuinely split and want a softer approach, name the options out loud, spin once, and give yourself ten seconds before you act on it. If you catch yourself hoping for a re-spin, you already know which option you prefer: pick that one and skip the second spin.

Three or more tied

A coin can't handle three people fairly in one flip. People try "odd one out," where all three flip and whoever doesn't match wins, but it can take several rounds and gets messy.

A wheel is simpler. Put the tied names on the random name picker, one per line, and spin once. Each name has the same chance: 1 in 3 for three people, 1 in 4 for four.

If you need a full order, say a tie for 2nd, 3rd and 4th place, leave remove winner on and keep spinning. The first name off takes 2nd, the next takes 3rd, and the last name on the wheel takes 4th.

Ties at game night

Most published games have a tiebreak rule buried in the manual. "Most resources left," "most cards in hand," "the player who went last." Look it up. It's usually there, and using it is fairer than chance because it's part of the game everyone agreed to play.

If the rulebook really says nothing, or it's a homemade game, a few options:

• Shared victory. Underrated. Nobody has to lose.
• A sudden-death round. One more question, one more roll.
• A random pick, if the group just wants to go home.

Whatever you choose, use the same method every time your group plays. Consistency matters more than which method you pick.

Ties in drafts and turn order

Fantasy leagues, pickup basketball captains, a family deciding who chooses the holiday destination this year. These are really about order, not winners. Randomize the whole order at once, in front of everyone, instead of breaking ties one at a time.

Paste every name into the name picker, keep remove winner on, and spin until one name is left. Write the order down as names come off. Post it in the group chat before anyone has time to suggest a different method.

Ties in votes

For small groups, a few principles work well.

• Re-vote after a short discussion. A 6–6 tie often breaks once people hear each other's reasons.
• Check whether a third option exists. Ties sometimes mean both options are a bit wrong.
• Fall back to your rules. If there's a casting vote, use it.
• Use chance only by agreement, and say it before you spin: "If we're still tied after one re-vote, we'll spin for it."

A worked example

Say three friends, Ana, Ben and Chris, are planning a trip and each wants a different city. They've talked for 40 minutes. Nobody has a stronger claim; every city fits the budget.

1. They agree: one round of "explain your pick in one minute," then a re-vote.
2. The re-vote is still three ways.
3. They agree, out loud, to spin. All three cities go on the name picker. Each has a 1 in 3 chance.
4. The wheel lands on Ben's city. Chris asks for "best of three." Ana and Ben say no, because everyone agreed on one spin, and after a bit of grumbling Chris starts looking up flights.

That last step is the whole point. The method was fair because they set the rules before they knew the result.

Frequently asked questions

What's the fairest way to break a tie between two people?

If neither has a stronger claim, a coin toss or a 50/50 spin. Agree who calls, what counts, and whether it's one flip or best of three before anything happens.

How do I break a three-way tie?

Put the three names or options on a wheel and spin once. Each has a 1 in 3 chance. If you need a full order, leave remove winner on and spin until one name is left.

Is a spinning wheel as fair as a coin toss?

On the yes or no wheel, each side has exactly the same chance on every spin, and spins don't affect each other. Real coins are very slightly biased toward the side they start on.

Can I flip a coin online on a video call?

Yes. Open the yes or no wheel, tap Heads / Tails, share your screen and spin, so everyone sees the same result.

When should you not use a coin toss to break a tie?

When one side has a better claim, or when your group already has a rule, like a casting vote or a rulebook tiebreaker. Use the rule first.
