Handle the timed prologue first, use 3141 for Mrs. Packerton's desk and 491145 for Henry's computer, then collect all eleven journal pages before the late basement route.
This guide is the no-miss layer. For the story order that finishes the Chapter, use Chapter 3: The Bologna Incident.
Don't Miss These in Chapter 3
Replay cuts, mutually exclusive awards, and the conversations that look optional. The Chapter route still has the story order if you only need to finish.
◉ Don't miss this: Keep the sticky tack instead of giving it away; it is needed for an optional collectible.
- Reading the white-room code in the wrong direction.
- Using 3141 on Henry's computer instead of the desk.
- Entering the basement route before confirming all eleven journal pages and Travis dialogue.
- Reading the timed white-room sequence in the wrong on-screen direction.
- Using 3141 on Henry's computer instead of Mrs. Packerton's desk.
- Reading 491145 as a date instead of the DIANE alphabet clue.
- If an achievement fails to appear after a clean run, compare the condition against the full achievement checklist before replaying.
Who Causes a Miss in Chapter 3
Skip these conversations or choices and you lock an achievement, a tool, or a later code. The rest of the people on this route are on the Chapter 3 roster.

Final Checks Before You Close Chapter 3
Confirm these while this save is still open. They are the last things that fail after a late sequence.
- Finish the timed journal route before committing to the school investigation.
- Use 3 → 2 → 3 → 2 with Travis and count all eleven journal pages.
- Keep the two code locations straight: 3141 opens the desk; 491145 is for Henry's computer.
Where Players Get Stuck
Protect the timed journal route
The white-room sequence is easy to rush. Set the controls before inputting the groups from right to left, then verify the reward path before starting the school investigation.
Keep the two main codes separate
3141 opens Mrs. Packerton's desk; 491145 is Henry's computer password. Treat the clue source as the check, because using the right number in the wrong location is the common error.
Handle Travis before the final school sequence
Find Travis in the bathroom and use the empathetic 3-2-3-2 dialogue pattern for Atonement. The conversation is optional in the story but not for a complete Chapter clear.
Count journal pages before the basement
The Missing Pages route needs all eleven journal pages. Search the school, apartments and Gear Boy interactions before committing to late objectives that limit backtracking.
Visual Clues
Official Steam screenshots. Use the caption to find the interaction. Codes that let the Chapter continue stay on the Chapter 3 puzzle list.
