Servant of the Lake Achievements Guide — All 49, Every Unlock

Servant of the Lake ships with 49 Steam achievements (confirmed on the Steam store listing). The list is unusually generous for a Rusty Lake game: almost every achievement is earned just by completing the story — each chapter and daily task is itself an achievement — with a few hidden extras layered on top for going off-mission. This guide lists every chapter achievement, every hidden one with its exact trigger, and the single long post-game secret that caps the list at 49.

Here's what you'll learn:

• Why the chapter structure means most achievements unlock by just playing
• Every hidden achievement for Day 1, Day 2 and Day 3 and its exact trigger
• The tricky ones: matcha latte, exercising with Aldous, seasoning the soup, finishing touch
• How the hidden "You've found him" ending chain works
• Whether the list is missable, and how the notebook replay helps you clean up

How Many Achievements Does Servant of the Lake Have?

49 on Steam, straight from the store listing's achievement counter. Rusty Lake's games usually ship far smaller lists (the Cube Escape games have a handful each), so this is one of the franchise's biggest. The list splits into two buckets:

• Chapter achievements — one for every named daily task across the three days. These unlock by simply completing the game's main story.
• Hidden achievements — roughly one layered onto each chapter, unlocked only by an off-the-beaten-path action during that chapter. These are what separates a normal finish from a 100% one.

Because every chapter can be replayed from the Servant's Notebook after you complete it, none of the hidden achievements are permanently locked out — they just require you to do the right thing at the right moment.

Chapter Achievements (Beat the Game, Get Most of Them)

Each of the three days contributes its named tasks to the list. If you finish the story, essentially all of these pop. The chapter names match the daily-task structure from the walkthrough:

That's the chapter backbone. The hidden extras in the next section are what push individual runs toward 100%.

Day 1 Hidden Achievements

Each hidden achievement unlocks by a deliberate action during its parent chapter:

• The Arrival — Petting the horse: before you feed it, tap the horse a few times around the eye to pet it.
• Preparing Breakfast — Feeding the cat: right after picking up the milk, feed some to the cat.
• Waking Up Aldous — Exercising with Mr. Aldous: during the exercise routine, deliberately mess up until Aldous gets stuck (bend him right, then left), then push him down straight. This one is reported as hard to reproduce consistently — plan for it on a replay.
• Preparing the Reception — Small repairs: keep dusting the small painting in the servant's room until it falls, then repair it from the pieces on the table once you have glue.
• Welcoming the Guests — Ruining the bouquet: before milking the goat, solve the flower puzzle and feed the flowers to the goat; the half-eaten bouquet then goes to Alexandra for the achievement.
• Serving Tea — Serving matcha latte: feed the cat some tea so it leaves a sticky mess, collect the green powder near Alexandra's crate, and add it to her tea along with the regular tea.
• Opening the Reunion — Soothing the baby: from the cupboard grab the champagne before anything else and pour a little into baby James's mouth.
• The Night Watch — Checking for intruders: at the glass garden door, keep checking the masked figure until the achievement triggers.
• Searching the Attic — Chase away the crow: scare the crow away in the window while solving the constellations.

Day 2 Hidden Achievements

• Preparing Coffee — Serving favorite coffee: roast the beans on the stove top (not in the flames) before grinding and serving.
• Waking Up William — Tickling Mr. William: once you have the feather, use it to tickle William (on his chest, and possibly his nose).
• Cleaning the Floors — Deep cleaning: while scrubbing the blood in the servant's room, scrub the Vanderboom drawing in the upper-left corner before finishing.
• Going Hunting — A perfect hunt: shoot William (twice) when you see him, then shoot every animal without missing a shot.
• Doing the Washing — Close inspections: look through the bathroom keyhole to spot the masked figure again.
• Helping with Bathing — Cleaning the windows: after Alexandra is in the bathtub, wipe each fogged window pane with your finger.
• Night Time Duties — Garbage disposal: before going down to the cellar, throw the animal parts over the balcony railing.
• Inspecting the Cellar — Pest control: after taking the key from the hole, tap the hole again for a mouse, then squash it with the hammer.

Day 3 Hidden Achievements

• Looking for the Cat — Petting the cat: when the cat is in the maid's lap, pet it until it jumps off.
• Assisting in Alchemy — Animal testing: once you have the elixir, pour some into the parrot's food bowl and let it drink.
• Unforeseen Maintenance — Checking the furniture: tap the table leg beside the cat to open a panel revealing a letter — do it while the cat is still there, or you can't get it.
• Preparing Dinner — Seasoning the soup: take the knife from the maid before the cake, use it to hit the fly, pick it up, and add it to the soup before the last ingredient; the human-fly then appears in the hallucination.
• Dressing Up for Dinner — Finishing touch: when arranging the house painting, put the fish in William's usual spot, take the fish pin from it, and pin it to the real William's jacket.
• Serving Dinner — Safety test: at the very start of the task, tap the rope a few times to check the chandelier.
• The Departure — First aid: once you have the fork, pull up Aldous's pant leg, pop the small balls from the holes, and close them up with your finger.

The "You've Found Him" Post-Game Chain

The final achievement is the capstone secret, triggered across a long post-game sequence that re-uses the notebook to reopen finished chapters:

1. After completing the game, you get a letter from Kate mentioning "the crow awakens at five past four." Go back to Waking Up Aldous on Day 1 and set the clock to 4:05 → a letter about a severed hand in Alexandra's suitcase.
2. Go back to Helping with Bathing on Day 2 and press the wall tiles for Alexandra, the bathtub, the suitcase, and the hand → read the maze letter, whose LEFT/RIGHT trail solves to RRRLRLRRL.
3. Back to Assisting in Alchemy on Day 3, enter RRRLRLRRL in the left/right box → another letter.
4. Return to Searching the Attic on Day 1 and draw the three constellations from the paper (structures, the two moons, then water) → another letter about the ruined ritual place.
5. Return to Dressing Up for Dinner on Day 3, go down to the cellar, and match the wine-bottle lock to the drawing (bronze on the spiral, silver on the snake, gold on the brow-mark) → crawl through the barrel.
6. Shake the red fabric for a note; solve the locked box with the crossed-off numbers, the painting window (2), the hunting eyeball (9), and the alchemy symbol (4) → 6294.
7. Take the telescope, aim it out the window at the building, and look in — You've found him!

This chain is fully explained step-by-step in the story explained page, including what the reveal means for the lore.

Are Servant of the Lake Achievements Hard?

No — the list is beatable and mostly grind-free. The chapter achievements drop from normal play. The hidden ones are clever but not difficult once you know the trigger; none involves a speedrun or a fail-state run of the whole game. The friction points are:

• Exercising with Mr. Aldous — the "get him stuck" trick is reported as annoying to reproduce; plan for it on a replay.
• The "You've found him" chain — long and multi-step, but entirely deterministic once you know the sequences. It's the one piece that reads like a true secret-hunt.

For a 100% route: beat the game first (chapter achievements + many hidden pop naturally), then use the notebook to replay each day once with the walkthrough open for the hidden triggers, and finally run the "You've found him" chain with the constellation, maze and wine-bottle solutions from the puzzles guide. That path covers all 49 without restarting the campaign.

Frequently Asked Questions

How many achievements does Servant of the Lake have?

49 on Steam, confirmed on the store listing. Roughly a third are chapter rewards, a third are hidden per-chapter extras, and a few are tied into the post-game "You've found him" chain.

What are the hidden achievements in Servant of the Lake?

One hidden extra per chapter, triggered by a deliberate off-script action — petting the horse, feeding the cat, getting Aldous stuck during exercise, ruining the bouquet, matcha tea, soothing the baby, chasing the crow, roasting coffee, perfect hunting, keyhole inspection, window cleaning, and more.

Is the You've found him achievement missable?

No — the post-game letter unlocks after you beat the game, and every chapter is replayable from the notebook. It's long and multi-step, but not missable.

Are Servant of the Lake achievements hard?

No. The list is completion-orientated: beat the game for most, trigger the known hidden actions for the rest. The only finicky one is "Exercising with Mr. Aldous" and the multi-step "You've found him" secret.

How do I get the matcha latte achievement in Servant of the Lake?

Feed the cat tea so it leaves a sticky mess, collect the green powder near Alexandra's crate, then serve it in Alexandra's tea along with the regular tea — rather than the plain sugar-sweetened cup.
