3Chess
A downloadable hex chess for Windows, macOS, and Linux
Three armies. One hex board. Every move helps someone you didn't choose.
Strike one, the other wins. Strike none, you fall.
A 3-player chess where calculation alone won't save you — you need to read the person across the table.
THE OPENING
Three sit down. A hex board. No one is across from anyone.
Face one, and your back is bare to the other.
The game has not started yet.
THE SILENCE
Ten turns pass. No one has struck.
Everyone knows — the first to attack opens their back to the third.
That silence is the loudest moment in the game.
KILL, OR SPARE?
Your friend is losing. You can end them now.
But if you do, their pieces lock the board. And the third player has been waiting for exactly this.
The move that does not kill is louder than the one that does.
THE KINGMAKER
You are losing. No way out.
But your last move decides who wins — the one who betrayed you on turn 12, or the one who never touched you.
The dying player holds the most power.
Trust lasts exactly one turn. There are no promises — only the move where you did not kill them, yet.
THE THREE
Gold · amber light on brass. Speaks last. Strikes hard.
Azure · iron under moonlight. Watches three moves ahead. Strikes when you forget they are there.
Crimson · blood on snow. Strikes first. Regrets second.
They are not teams. They are never allied. Any two of them lose to the third.

A NOTE FROM THE MAKER
I'm one person in Thailand. I built this because engines can solve two-player chess flat — they cannot solve a table that reads you back.
Three kings. Three wills. One board that does not forgive.
— Round Online
A PRIVATE TABLE
Casual rooms between friends are end-to-end encrypted. Only the three players hold the key.
When the game ends, the server forgets.
Ranked and matchmaking are different — the server records those for anti-cheat and rating. But if you and two friends want to play like you're sitting at a table with no one watching, you can.
WHAT THE BOARD ASKS
Chess asks how well you think. This board asks how well you read people.
If you lose, it will be because you trusted the wrong person. And you will want to come back.
The rules are chess. The game is not.
