Play a real game of chess against a friend, glasses to glasses, at your own pace. You both enter the same game code — first in is White, second is Black — and take turns: D-pad moves a cursor, Enter picks your piece (legal destinations light up), Enter again places it. The full rules run on-device — legal moves only, check, checkmate and stalemate detection, auto-queen promotion — and your move syncs to your opponent within a few seconds. It’s asynchronous: glance, move, come back later. No accounts, no login; the server only relays the board (60-min idle TTL). On the see-through display “black” pieces glow coral and “white” glow bright so both sides read clearly.
