Open Challenge
Create an Open Challenge
Make a private local-review room, share its code or invite link, and let each player start whenever ready.
Before you start
- Use a local review server with multiplayer enabled on the same machine. The room API accepts loopback requests only, so another device cannot join through the generated link; there is no hosted room service here.
Steps
Open room choices
From setup, choose Challenge friends. If this is the first guest action, save a nickname first; after that the mode chooser opens.
Open the Rooms: choose a mode guideCreate an Open Challenge
Optionally enter a room name, then choose Create challenge. It uses the current addend and duration settings; room settings cannot be changed after creation.

Copy the six-character code or private invite link, or display the QR. Keep the long-token link private. This local loopback URL cannot be used from another device; code-only entry is also for local review.

Choose Play now in the room. Open Challenge has no ready-up gate; the host can play before anyone else joins.

What to expect
- The room is private and is not listed in a public directory.
- The app marks local review clearly; room links are not public production invitations.

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.
Open Challenge creates a private room for independent timed rounds and best-score comparison.
Choose a harmless room name, create the challenge, then copy its code or invite link. The private code, URL and QR are hidden in this recording.
An invited guest joins with the code. The host can see the participant, start a round, or end the room.
After the timer ends, the room returns an accepted receipt and updates its local standings. This local review score is not learning evidence.
