Big Walk Purple Challenges: All 7 Post-Game Puzzles

How to Unlock the Purple Door

The seven purple challenges live behind a purple door in the area behind the eastern cable car point. Finding that door is itself the first test of how well your group learned the island’s cable car network. Completing the challenges and forging the white key they lead to unlocks the true ending. Come prepared: several challenges assume your group has mastered the tools and toys — especially the whiteboard and flashlight.

The Seven Challenges

1. Wait 30 Minutes House

A house whose door simply requires the group to wait inside together for thirty real minutes. There is no trick, no timer skip — the challenge is whether your group can actually talk for half an hour. Veterans use it for a snack break. It’s the game’s quietest joke and a deliberate pacing valve.

2. Golf — But You Can’t Throw

A golf-style objective where the ball may only be carried by hand and passed between players — throwing is disabled. Strategy: form a bucket brigade, call distances, and never let the ball carrier also be the navigator.

3. 36 Drawings

Thirty-six drawings must be placed on walls by teammates who cannot see the reference; one viewer calls them out. Brute-force descriptions fail — the intended solution is disciplined whiteboard work: viewer sketches, field players confirm, place, repeat. This is the longest single challenge.

4. Nine Speakers, But You Can’t Talk

Nine speakers must be activated in the right order while the game mutes normal voice chat. Strategy: assign numbers via emotes or megaphone taps before entering, and use the radio sparingly — it still works, but treat it as a backup, not the plan.

5. Nine Symbols

A grid-matching challenge in the classic symbol family: one player sees the nine symbols, others place them. The puzzle solutions guide covers the general method — whiteboard plus radio confirmation.

6. Platforming, But Do It Fast

A timed platforming course. No communication trick here — pure execution. Let your group’s most practiced platformer run it, with everyone else silent except hazard callouts. Checkpoint discipline beats speed.

7. Many Lights Everywhere

The finale: a field full of lights where normal speech is useless. The agreed protocol is flashlight morse — one flash means “yes,” two flashes mean “no” — to answer a long sequence of binary questions while surrounded by noise. Slow down. A wrong answer costs more time than a careful double-check. This challenge is the reason the one-flash/two-flash convention exists, and it pays off directly at the true ending.

Rewards

The challenges feed the purple blorb chain that forges the white key — the key to the true ending. Collectively they also complete several of the game’s 12 achievements.

Group Tips

• Budget a full session for all seven; rushing the later ones is the top cause of failure.
• Designate one “caller” per challenge — democracy is slow when only one player can see the information.
• If voice gets heated, take the Wait 30 Minutes House first. It resets the mood, literally by design.
