Ruleset and how to connect

Two devices, one game. Only moves and hashes cross the wire — the board is never sent. Both sides must be on the same ruleset, or the connection is refused.

How to connect

Both players must use the same method.

The host gets a short code and the guest types it. The introduction runs through the public PeerJS server — a third party. Once connected the game is still device to device: moves and hashes never pass through that server.

Host

You make the code and your friend enters it. You hold Player A and move first.

Join

Your friend makes the code and you enter it. You hold Player B.

No TURN relay. Some connections — particularly when both sides sit behind strict NAT — will simply fail, and that cannot be fixed from this end.
