Servant of the Lake has 49 Steam achievements. About half are story achievements that unlock as each block of the day ends — you cannot miss those. The rest are hidden, tied to optional interactions, and disappear when their day-block does.
This page lists them in the order you reach them, with the official in-game clue where the game provides one.
Day 1 — Morning
Petting the Horse — "Something wiggles! One click may not be enough." Courtyard. Click the horse, glasses included, over and over before you feed it the carrot.
Feeding the Cat — "Kitty wants something. What do cats love?" Hallway. Give Rustie the milk before the dead mouse.
Exercising with Mr. Aldous — "You have to make him move. How to fail at this task?" Bedroom. Do the exercises wrong on purpose until Aldous complains he is stuck. See the exercise puzzle page.
Day 1 — Afternoon
Small Repairs — "What else can you dust? There is more than three paintings." Hallway. Keep dusting past the obvious three portraits.
Ruining the Bouquet — "The goat deserves more attention. Alexandra isn't the only one loving flowers." Garden. Let the goat chew the bouquet before handing it to Alexandra.
Day 1 — Evening
Serving Match Latte — "The cat also likes herbs. Maybe Rusty puked more than once." Put the green powder in Alexandra's tea.
Soothing the Baby — "Someone else wants a drink. Why is this baby so fussy?" Give the champagne to baby James, not William.
Waking William — parlor. Click his hat, ears and tie and read which way his eyes point to pick the next one.
Day 1 — Night
Checking for Intruders — "Be Thorough. Are those specters?" Go back to the corridor window where you served the tea.
Chasing the Crow — "Many things are staring from the window! Click on that bird!" Attic. Move in and out of the containers until the crow appears at the window, then click it.
Day 2 — Morning
Serving Mr. Aldous his Favorite Coffee — "Green Coffee isn't the tastiest. Roasted Coffee Beans are better." Roast the beans before throwing them on the stove.
Tickling Mr. William — "You have a feather! Toes aren't your only victim." Use the feather on his face, not his feet, until he says stop.
Day 2 — Afternoon
Deep Cleaning — "There is blood and what else? This drawing is helpful but…" Scrub the family portrait in the kitchen with the brush.
A Perfect Hunt — "There are only 5 targets. 10 bullets are enough." Five targets, ten bullets, no missed shots at all. A miss counts even with ammunition to spare.
Day 2 — Evening
Close Inspection — "You don't need a key to see inside. Who is in the bathroom?" Look through the second-floor bathroom keyhole.
Cleaning the Windows — "Something else needs to be cleaned. The windows are a little foggy." Wipe the window after Alexandra is in the bath.
Day 2 — Night
Garbage Disposal — "This is disgusting! Throw them down! The balcony isn't a trashcan!" On the balcony, throw everything over the edge.
Pest Control — "The hole is inhabited. Use the sledgehammer!" Three steps, and most players stop after the first: magnet to pull the key out → click the hole again to draw the mouse out → sledgehammer it when it returns.
Day 3 — Morning
Petting the Cat — "Rusty is calm now. More than once, he was loose poor thing." Stroke Rustie on the maid's lap.
Animal Testing — "Someone else can taste it! Give him some Elixir." Give the elixir to the parrot.
Furniture Secrets — under the kitchen table, click the second leg from the left for a note.
Seasoning to Taste — kill the fly near the cake with the knife, then drop it into the soup.
Risk Assessment — dining hall. Click the rope at the upper left repeatedly.
First Aid — click Aldous's leg to treat the wounds, then pull the fork out of his shoulder.
