Hello, board ·
Introducing Castle Gambit.
An app for the oldest social network in chess: a room, a bag of boards, and whoever turns up on Tuesday.

The short version
- Find a game the moment you walk in
- A friendly rating from games across a real board
- Find clubs and open games near you
- Tools that give organizers their evening back
Every town has a chess club, and every chess club runs on the same three things: a key to the room, a bag of boards, and one heroic person with a clipboard.
Castle Gambit is for that room. It finds you a game the moment you walk in, keeps a friendly rating from the games you actually play across a real board, and hands the person with the clipboard their evening back.
What’s in the box
- Club night on your phone. Scan in, tap once, get a board.
- A social Elo that only counts the games you play in person.
- Castles and Gambits. Clubs near you, and open games you can say yes to.
- Tools for organizers, from the first poster to the last result.
About the name
There’s no such thing as the Castle Gambit. Look it up. It sounds like an opening, which is exactly the point: it’s the question we hope you ask across the board. Here’s the whole story.
