What Am I Missing? Big Walk Progress Solver
Tick what you've already done. The solver compares your state against the game's deterministic progression order and tells you the most likely missing step — with the reasoning and a confidence score. Nothing is saved to a server; your state stays in your own browser.

How the diagnosis works
The solver applies deterministic rules first — the world's key order is fixed and the Map Room is the first real gate. Only when your state can't be explained deterministically does it fall back to community-verified "most likely next step", and it always says so. This is a heuristic tool, not an AI oracle: if you're genuinely stuck on a puzzle inside an area you've already unlocked, check the puzzle types page instead.
What "confidence" means here
- High — the missing step follows from the deterministic key order. One gap in the chain explains almost all "where do we go?" questions.
- Medium — the step is community-corroborated across multiple guides and play-throughs, but the exact trigger isn't officially documented.
- Low — the step depends on a specific puzzle or achievement branch we couldn't verify from reliable footage yet.
Spoiler policyThis page only tells you what you're missing. For how, every linked guide gives you the no-spoiler hint first — you choose how deep to go.
Common "stuck" patterns
"We have the Red Bridge Key but no idea where to go"
Take it to the Map Room first — that's what the key opens. After that, follow the tower landmarks west to east.
"We're at the Black Sphere with no key"
The Black Tower Key lives at the Black Sphere. You're right where you need to be; the map guide covers the final key's puzzle hub.
"We finished the game — is there more?"
