Bowling takes two screens. This page, on a laptop, is the lane; your phone is the ball. Open this address on a laptop and scan the code it shows.
Opens the laptop page on this phone instead.Bowl with your phone. The laptop is the lane.
Your phone is the ball. Pair it once, then pass it round. The game itself goes straight from your phone to this laptop — only the one-time introduction passes through a small relay, and it is deleted as soon as it is used.
Use the camera app. It opens the ball page and links by itself — same Wi‑Fi as this laptop.
The phone will display a second code. Hold it up to this laptop’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 this laptop’s camera.
Click a name to change it. RIGHT / LEFT is the hand they bowl with. Both change at once, even mid-game.
