A friend. A room code.
A new dimension.

Create a private room

1. Open Play → Online opponent.
2. Continue as a guest, or sign in with Apple or Google.
3. Create a private room and choose a clock.
4. Share the room code or QR invitation with your friend.
5. Wait for the second player to connect and follow the in-app game status.

Join a friend

Choose the join option and enter the room code, or scan the QR invitation. Camera access is only needed for scanning; typing the code works without it. Keep room invitations between the people you want to play with.

Find an opponent

Matchmaking needs another player looking for the same clock. If no match appears, wait, try another clock, or arrange a private room with a friend. A waiting screen is not a promise that an opponent is already available.

Connection and room history

Both players need a connection. Follow the game’s connection and clock status if service is interrupted. Waiting rooms expire after 24 hours; active rooms expire after 30 days without an accepted move. Finished or expired room history is retained for 30 days, with cleanup potentially completing later.

Check the expiry shown in the app and export a finished game if you want to keep it. Online history is separate from offline saves.
