Invokyr secrets
The secrets with dates attached are physical rooms and notes, not a list of cheat toggles. The attic safe, the moving bookshelf, and Henry’s bedroom letter are the three I will describe. Anything without two sources stays labeled as a single report.

I kept the October 8 password thread, the October 9 bedroom post, and the October 12 shelf post in separate piles. The fun part is that they connect: the safe key is not Henry’s key, and the letter is not the combination. I am not spoiling the letter’s plot beyond “it is a long letter.”
What you can actually go look for
Traditional Chinese searches for 密碼彩蛋 land on the same attic note: a September 13, 1987 clue that players turned into 091387. That is the egg with a number. The route is on the safe-code page.
The tilted book is the second egg. It opens a study that does not spawn every run. Henry’s key is tied to that room, with the caveat that one October 12 player opened the shelf and still found no key.
- Attic desk note and Class of ’87 book: combination clue.
- U-shaped shelf, one crooked book: hidden study.
- Henry’s bedroom: television, wardrobes, a long letter. Plot not reprinted.
- Echo die near the hall fireplace: highlights wood, a rug crease, and a handprint. Clue, not a code.
What this page will not list
Trainers, ESP, and cracked executables are not secrets of the game. The mods page says what community changes are even discussable. A “Jumanji” comparison is on the games-like page, because that is a genre question, not a hidden room.
Questions this page answers
What is the Invokyr easter egg code?
Players read 091387 from the attic’s 1987 note. It opens the attic safe, not a debug menu.
Is Henry’s letter a code?
Posts describe it as story. No one in the sourced threads turns the letter into digits.
