01 · Steps
Recommended approach
What to know
Start by checking the tower and the surrounding area so your group knows what must be returned. Choose nearby puzzles based on what you have already completed and which paths are open.
- Meet at Yellow Tower
- Identify available nearby challenges
- Split only when communication remains reliable
- Return rewards to the tower
- Take the key and open the tunnel
02 · Guide notes
What is not confirmed
What to know
The five puzzles commonly shown in third-party walkthroughs are a recommended route. They should not be described as the only five rewards that can ever support the tower.
What this guide does not claim
Community labels are not presented as official names. Approximate coordinates stay marked as approximate, version-sensitive facts need a publication-day check, and no unsupported platform, code, solo route or mod-only shortcut is invented.

How current is this information?
The source pack was reviewed on August 17, 2026. Platform status, prices, versions and live service information must be checked again on the publication date.
Are community puzzle names official?
Not necessarily. Big Walk does not provide an official name for every challenge, so this site identifies player-made labels whenever that distinction matters.
