NEW BESTYour phone is the racket. Pair it once, then swing. The game itself goes straight from your phone to this screen — only the one-time introduction passes through a relay, and it is deleted the moment the two are linked.
Use the camera app. It opens the racket page — same Wi‑Fi as this screen.
The phone will display a second code. Hold it up to this screen’s camera.
This screen looks like a TV, and a TV has no camera, so the other way — your phone showing a code back to this screen — cannot work here. What usually fixes it: put the phone on the same Wi‑Fi as the TV (not a guest network, which often stops devices reaching each other), then press START OVER for a fresh code.
One code. Your phone answers through a small relay instead of a camera, so there is nothing to hold up — and the introduction is deleted the moment the two are linked.
Practise the timing while you wait: press Space or click the court. That click also turns on the court's sound.
