Quick answer

Follow Day 1 → Day 2 → Day 3. Use the code sheet for locks, then use the visual steps when the problem is an item order or a click target. Screenshot captions identify Steam Community material; editorial illustrations are atmosphere only.

01
Day 1

Arrive, prepare, and learn the house.

  1. 01Start with the arrival actions. The Steam guide reports the horse interaction as a ten-click optional check.
  2. 02Clear the morning duties. Breakfast, waking Aldous, and the first house interactions sit before reception.
  3. 03Inspect before rushing. Portrait cleaning and the bouquet detour are optional achievement checks.
  4. 04Finish the night sequence. Check the white door and the attic/crow interactions before Day 2.

  1. 01Roast before grinding. Green beans are not enough; roast them on the stove first.
  2. 02Use coffee box code 315. If the scene does not advance, return to the item-order step instead of trying another code.
  3. 03Save the perfect-run attempt. The community route describes six targets with nine shots; treat it as an optional achievement check.
  4. 04Finish bath and cellar checks. Use 281 for the briefcase, then 5:00 → 8:00 → 10:00 in the cellar.

  1. 01Find the cat first. Tap the cat’s head until it runs away for the optional check.
  2. 02Open the lab cabinet with 2451. Recipe order: egg first, then 1 juice, 1 acid, 1 oil, and 3 blood.
  3. 03Use LLRRLR at the left/right box. Keep this separate from the disputed secret-ending branch.
  4. 04Keep dinner as a checkpoint. Public coverage still has a replay gap around the full dinner sequence.

FAQ

A few route questions

How long is Servant of the Lake?

Official launch coverage describes the main story as roughly four to five hours; puzzle speed and optional achievements change the total.

Where is the Day 2 coffee code?

The launch-build walkthrough sources report 315 for the coffee box. The walkthrough notes that the beans should be roasted before grinding.

Is the Day 3 dinner route fully verified here?

Not yet. The source coverage used for this MVP still signals a gap around dinner, so this guide labels that segment replay pending.
