Do this first
The quick route
- Finish the first ending and return to the same hosted save.
- Check the large Map Room map for seven new purple markers.
- Ride the chairlift toward the far eastern challenge ridge.
- Enter the purple tunnel and scout all seven setups.
- Bring a consistent group and agree on gesture codes before communication puzzles.
- Use the host accessibility setting to skip a challenge that is not accessible.
Spoiler boundary: when they unlock
Stop here if your group has not reached the first ending. The purple route is post-game content. Once the credits have rolled, return to the same world and look for new purple markers on the large map and the tunnel near the eastern ridge.
What the seven challenges test
Current walkthroughs describe remixed versions of earlier ideas: a long-distance golf-ball delivery, silent symbol and speaker communication, a 36-drawing identification puzzle, timed platforming, a many-lights relay, and a 30-minute waiting room. Exact roles can adapt to world size.
Prepare before splitting up
Keep walkie-talkies, a map, and one agreed landmark system with the group. For silent challenges, define simple hand or light signals before someone enters the restricted area. For the long transport challenge, use short relays and protect the carried object around the chairlift.
Accessibility and completion
House House says the host can enable challenge skipping when starting a session. That option is intended for challenges requiring hearing, speaking, reading, reaction speed, or fine motor control and does not need to be treated as a failure.
