Servant of the Lake: How to Unlock All 49 Achievements

Servant of the Lake has 49 achievements, and most of them are missable. You earn a set of them just by finishing each task in order, but the rest hide behind small, deliberate actions you can walk right past. The trick is knowing the exact moment to break the routine before a scene moves on.

Quick answer: Complete all three days to collect the task achievements automatically, and perform each hidden action below during its matching task. The 49th, You’ve Found Him!, only appears after you finish the game and follow the maid’s letter chain back through earlier tasks.

How the achievements are split

Each task in the game has two achievements tied to it. One unlocks when you finish the task normally, so simply playing through the story clears roughly half the list. The second is a hidden action inside that same task, and many of these are timing-sensitive. If you advance past the trigger, the only way back is to replay that chapter.

An achievement fires with an on-screen pop-up the moment its condition is met. If nothing appears, you either skipped the exact action or did it in the wrong order. The tables below list only the hidden triggers, since the completion achievements need no explanation beyond finishing the task.

Day 1 hidden achievements

Achievement	Task	How to trigger it
Petting the Horse	The Arrival	Tap the horse’s face near the eye and ears repeatedly to pet it before feeding the carrot.
Feeding the cat	Preparing Breakfast	Right after picking up the milk bottle, give the cat some milk before you hand it the dead mouse.
Exercising with Mr. Aldous	Waking up Aldous	During the exercise step, click Aldous the wrong way until he freezes in one position, then push him to straighten up.
Small repairs	Preparing the Reception	Dust the small picture in the Servant’s Room until it falls, then reassemble the pieces on the table.
Ruining the bouquet	Welcoming the Guests	Solve the flower puzzle and feed the bouquet to the goat before milking it, then give the ruined flowers to Alexandra.
Serving Matcha Latte	Serving Tea	Feed the cat some tea, collect the green powder from the crate in the hallway, and stir it into Alexandra’s tea alongside the normal tea.
Soothing the baby	Opening the Reunion	Take the champagne from the cupboard and pour some into baby James’s mouth before handing him to William.
Checking for intruders	The Night Watch	Look out the glass garden doors in the back hallway until the masked figure appears. Keep checking if it doesn’t show.
Chase away the Crow	Searching the Attic	While solving the constellation puzzle, click the crow in the attic window to scare it off.

Note: Feeding the cat and Soothing the baby both lock out if you progress the scene first. If the cat is no longer grooming itself when you arrive, you have already taken the mouse and must restart the task.

Day 2 hidden achievements

Achievement	Task	How to trigger it
Serving Mr. Aldous his Favorite Coffee	Preparing Coffee	Roast the coffee beans on top of the stove (not in the flames), then grind them and brew as normal.
Tickling Mr. William	Waking up William	Use the bird feather to tickle William’s nose, chest, and feet.
Deep Cleaning	Cleaning the Floors	While scrubbing the dirty spot in the Servant’s Room, drag the scrubber over the stick-figure drawing before letting go.
A Perfect Hunt	Going Hunting	Shoot every target without missing: Rabbit, Pheasant, Pigeon, Deer, Boar, and William (some require two shots).
Close Inspections	Doing the Washing	Look through the keyhole in the bathroom door to spot the masked figure.
Cleaning the Windows	Helping with Bathing	After Alexandra is asleep in the tub, wipe each fogged pane of the bathroom window clear.
Garbage Disposal	Night Time Duties	Step onto the balcony beside the bathroom door and throw the strange objects over the railing.
Pest Control	Inspecting the Cellar	Use the magnet on the cellar mouse hole to pull out the key, use it again to draw out a mouse, then crush it with the sledgehammer or weight.

Day 3 hidden achievements

Achievement	Task	How to trigger it

You’ve Found Him: the final achievement

This is the true ending and the last achievement. It is a chain that sends you back to specific tasks across all three days, each unlocking the next letter from the maid, Kate. Continue the game after completing it to begin.

Read the first letter from Kate. It reads, “The crow awakens at five past four.”

Return to Waking up Aldous on Day 1 and set the alarm clock to 4:05. A letter appears describing a severed hand inside Alexandra’s suitcase.

Go to Helping with Bathing on Day 2 and use the tile wall. Press Alexandra, then the Bathtub, then the Suitcase, then the Hand. Read the note behind the loose tile to reveal a maze with LEFT and RIGHT symbols. The path solves to RRRLRLRRL.

Return to Assisting in Alchemy on Day 3 and enter RRRLRLRRL into the left/right box. Another letter unlocks.

Go back to Searching the Attic on Day 1 and open the constellation box. Build three constellations from the images on the letter, grouped as structures and windows, then the two moons, then the water symbols. A new note follows.

Head to Dressing up for Dinner on Day 3, go down to the cellar, and set the wine bottle combination box to match the drawing on the note. This unlocks the next letter.

Solve the bottle placement in that same cellar. Put the bronze bottle on the spiral, the silver bottle on the snake, and the gold bottle on the triangle with a horizontal line, matching the mark on James’s forehead. Climb through the open barrel into the hidden room.

Shake the red fabric until a note falls, then open the locked box using the code 6294. The 6 comes from crossing off numbers with the note’s marks, the 2 from the matching window in the Preparing Coffee painting, the 9 from the eyeball in Going Hunting, and the 4 from the symbol in Assisting in Alchemy. Take the telescope inside.

Stay in the room, go to the window, and use the telescope to view the building outside near the dining room. Finding that hidden location closes out the story and unlocks You’ve Found Him.

Once the final letter chain resolves and the ending plays, all 49 achievements register on your account and the game shows as fully completed. If a task achievement never popped, load that specific chapter again and repeat only its hidden action, since the story completion ones are already banked.
