Puzzle Checklist & Codes

Where Each Code Comes From

Most Endacopia codes are written down in plain text somewhere in the game — you are expected to find them, not guess them. Some are told to you directly by NPCs.

Code	How you find it
Cheshire	Dialogue with the Wall Bank cat after depositing coins
Yellow	Told by the owl host at the Condo party
471	Henry’s PASSWORDS.TXT on his desktop
Green / Green / Red X	Cooler mug interaction — colours appear on the outlet
Waterfall Code	Hidden note in the Timesville shack; opens in Chapter II
Safe Code	Note in the Office break-room drawer
Core Room Code	Note on the AI’s terminal after the Henry fight
Lockbox Code	Note pinned to the Timesville shed door
Fridge code	Dialogue with the fridge when first opened

Stay Secrets — Code Chain

The Stay ending depends on three secrets, each with a code or item chain:

Secret	Item / Code	Link
1. Misery Town	Projector Remote + Map	Projector Remote
2. Timesville	18 fish + Fish Paper → Lost Key → Waterfall Code → Safe	Waterfall Code
3. Office	Telescope → bench number → Jobs app → Morse code	Brain Scan

If any one secret is missing, Stay does not trigger in Chapter III.

Code-Gated Missables

A handful of codes are missable if you progress past their window:

• 471 / Saw Box — once opened, you can only hold one saw (Escape or Return, not both)
• Waterfall Code — only appears after Timesville Chapter II
• Brain Scan password — only available after the AI skip or fight
• Core Room Code — only readable after Henry
