Review the projected-room flow locally
Rehearse the Open Challenge code and QR screen; loopback-only review links cannot be reached from participants' separate devices.
Before you start
- Use a local review server with multiplayer enabled on the same machine. Its room API accepts loopback traffic only, so the code and QR cannot connect a class on separate devices. This is a UI-flow rehearsal, not a classroom deployment.
Steps
Create an Open Challenge
Create a room and keep its room screen visible on the projected display. The screen shows a private code, invite URL, QR, participant list, and best scores.

The room UI exposes the invitation controls, but a loopback URL cannot connect phones or other computers. Use this step to review the local flow only; cross-device hosted invitations are unavailable.

The local implementation can be exercised from browser sessions on the same machine. It does not provide a supported separate-device classroom session.

As host, end the challenge to freeze its standings. Create another room for a new session. The app does not provide rosters, student records, exports, or a gradebook.

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.
Create a harmlessly named Open Challenge and keep the room screen visible on a desktop.
Share the private code, invite link or QR with intended guests. This local review room is not hosted; invite data is hidden in the recording.
Synthetic guests join from separate browser contexts. Their names appear in the room roster.
As each guest finishes an independent round, the host view refreshes to show accepted best scores and ranks.
End the challenge when the session is over. This preview does not provide a class roster, gradebook or learner records.
