A decision maker for two options

Most stuck decisions are not hard, they are just evenly matched. Put one option on each side of a coin, flip it, and move on — alone, or with the person you cannot agree with watching it land.

Name your two options

Put your own labels on the coin

Choose singleplayer when you set up your flip and you can rename the two sides. Instead of Heads and Tails the coin carries “Pizza” and “Salad”, “Beach” and “Mountains”, or the names of the two people who both want the window seat. The result is announced in your words, so nobody has to remember which option was heads.

Deciding with someone else? Send them the read-only watch link before you flip. They see the same coin land at the same moment you do, and the outcome comes from the server rather than from your device — so nobody has to take your word for it.

The coin flip trick

There is an old piece of advice: when you cannot choose, flip a coin — not to obey it, but because while it is in the air you will suddenly notice which side you are hoping for. If the result disappoints you, you have your answer, and you are free to ignore the coin.

And if you feel nothing either way, the options really were equal, and going with the flip costs you nothing. Either way you stop circling.

For decisions between two people

A coin is the fairest tiebreaker there is, provided nobody controls it. If you would rather each hold a side than watch, open a multiplayer room instead: you each take a face of the coin, both press ready, and the server decides — with a cryptographic commitment made before the flip. For anything that deserves more ceremony, make it a best of 3.

Questions

Can I use it for more than two options?

A coin has two sides, so it decides between two things at a time. For more options, run it as a bracket: flip between pairs, then flip between the winners.

Does the other person have to be online?

No. In singleplayer you flip alone, and the read-only watch link is there for anyone who wants to see it happen live.

Are the custom labels saved anywhere?

They live with the room, and rooms expire after thirty minutes of inactivity. There are no accounts, so nothing is tied to you.
