Open Challenge
Join an Open Challenge
Enter a private local-review room from an invite link or six-character code, then play without waiting for the host.
Before you start
- Open the invite in a browser on the same machine as the loopback-only local review server, or get its six-character code there. A first-time guest needs a nickname.
Steps
Open the invite or room chooser
A valid invite link opens the exact room. To join manually, choose Challenge friends, enter the six-character code, and choose Join room.
Open the Open Challenge: join by link or code guideEnter a nickname if prompted
A new guest enters a room-visible nickname once. Closing the sheet cancels the join. A returning guest reuses the same browser identity.

Check its name, stored settings, participant list, private code, and current best scores. An Open Challenge participant can play as soon as they join.

For a malformed, missing, or expired room, check the code or invite, return to the chooser, or ask for a fresh invite. Solo play remains available.

What to expect
- A direct link on the local review machine does not ask you to enter the room code or settings again.
- The loopback-only service cannot be joined from a separate device and does not create a public hosted room.

Visual guide
Recorded walkthrough
These are silent local synthetic preview captures. Account clips and screenshots show the unconfigured guest preview, not the locally prepared member flow. Some demos use 5-, 15-, or 20-second timers; private invitation details are hidden. If playback is unavailable, use the captions when present or read the full transcript below.

This capture uses a synthetic five-second round to keep the local demonstration short.
A room host shares a private invite link. The code, full URL and QR are hidden in this guide.
Opening a valid link takes the guest to the matching private room. The guest name is shared with that room only.
Play a round and wait for the room’s accepted receipt before reading the score as part of its standings.
Back to the room, then reload to rejoin with the same guest session and room invite.
A manual six-character code is also available from the Create or join a room screen.
