Read the list by task and reward type

The tables below keep achievement names distinct from assignment names. Small Repairs, for example, is an optional action inside Preparing the Reception; Unforeseen Maintenance is a later story assignment. The same house view can support several different rewards.

The list covers the premium Steam game. Check rewards in the achievement list for the version you are playing; completing a mobile task does not establish that a Steam reward has synchronized.

AchievementReplay chapterAction and completion condition
Petting the HorseDay 1 Morning · The ArrivalPet the horse’s head repeatedly until it lowers its head. Do this before the coach departs; the guide’s successful run fed it first.
Feeding the CatDay 1 Morning · Preparing BreakfastGive milk to the cat while it licks its paw, before picking up the dead mouse. The milk-lick interaction confirms it.
Exercising with Mr. AldousDay 1 Morning · Waking up AldousBefore the correct exercise, make incorrect bends until Aldous gets stuck, then click him to straighten him. The release-era authors do not establish one repeatable wrong-input code; later Steam notes changed repeat behavior. See Aldous exercise.
Small RepairsDay 1 Afternoon · Preparing the ReceptionAfter receiving the duster, keep dusting the small servant-room picture until it falls. Reassemble its pieces. See Small Repairs.
Ruining the BouquetDay 1 Afternoon · Welcoming the GuestsFeed the solved bouquet to the goat BEFORE milking, then give it to Alexandra after she arrives. Her goat-smell comment completes it. See bouquet choice.
Serving Matcha LatteDay 1 Evening · Serving TeaFeed tea leaves to the cat BEFORE making it cough up glue. Collect green powder from the crate behind Alexandra and add it to her tea along with the normal ingredients. See Matcha Latte.
Soothing the BabyDay 1 Evening · Opening the ReunionCollect champagne from the 1753 box and use it on James’s mouth before William consumes the bottle. This optional interaction differs from the crying sequence. See Soothing the Baby.
Checking for IntrudersDay 1 Night · The Night WatchInspect the garden entrance during patrols until the masked figure appears. The patrol/anomaly order varies; inspect that view on each circuit.
Chase away the CrowDay 1 Night · Searching the AtticWhen the crow appears at the attic window during the constellation sequence, click it to chase it away. See attic window.
Serving Mr. Aldous his Favorite CoffeeDay 2 Morning · Preparing CoffeeRoast the coffee beans ON TOP of the stove, beside the pot rather than in the flames, before grinding. Make and serve the coffee to Aldous.
Tickling Mr. WilliamDay 2 Morning · Waking up WilliamUse the feather on William’s nose and nipples until he says “Stop it.” Do this before finishing the toe puzzle. See William’s feather.
Deep CleaningDay 2 Afternoon · Cleaning the FloorsAfter clearing the final blood spot in the servant’s room, keep the scrubber held and clean the faint family drawing at upper left BEFORE releasing it.
A Perfect HuntDay 2 Afternoon · Going HuntingWaste no shots. Shoot pheasant, pigeon, the boar’s shadow then boar, the rabbit’s rock then rabbit, deer, and William at both his appearances. Refill at the stump between sets as needed; his later appearance is in the river.
Close InspectionsDay 2 Evening · Doing the WashingPeek through the bathroom keyhole while gathering the clothes upstairs and find the masked figure. Do it before unlocking the bathroom.
Cleaning the WindowsDay 2 Evening · Helping with BathingAfter Alexandra is in the bath and the window has steamed up, wipe every pane and inspect the figure. See bathroom follow-up.
Garbage DisposalDay 2 Night · Night Time DutiesBefore entering the cellar, throw the remaining animal parts over the balcony railing.
Pest ControlDay 2 Night · Inspecting the CellarTake magnet and sledgehammer among your three tools. In the left room, extract the mousehole key with the magnet, click the hole until the mouse runs out, and use the hammer on it. Rewind afterward to continue the normal tool route.
Petting the CatDay 3 Morning · Looking for the CatOnce Rustie returns to Kate’s lap, pet the cat repeatedly until it jumps off. Do this BEFORE clicking Kate to finish the assignment.
Animal testingDay 3 Morning · Assisting in AlchemyAfter mixing the elixir, pour some into the parrot’s bowl and let it drink BEFORE handing Aldous the whole bottle. See elixir serving.
Checking the FurnitureDay 3 Afternoon · Unforeseen MaintenanceOpen the table leg beside Rustie while the cat is still there and read the letter. Do it BEFORE making the cat cough up glue or leave.
Seasoning the SoupDay 3 Afternoon · Preparing DinnerUse the knife on the fly at the cake, take the dead fly and put it in the soup BEFORE adding the last soup ingredient. Continue to the soup hallucination, where seeing the fly triggers the achievement.
Finishing TouchDay 3 Evening · Dressing up for DinnerIn the house painting, move the fish to William’s portrait position: use the third window on the second row from bottom, then the far-right fish window. Take the pin from the changed portrait and put it on the real William BEFORE his tie. Restore the ordinary portrait arrangement to continue the cellar clue.
Safety TestDay 3 Evening · Serving DinnerAt the start of dinner, pull the chandelier rope at upper left several times until Aldous comments. Do this before completing the serving sequence.
First AidDay 3 Departure · The DepartureLift Aldous’s trouser leg. Use the fork twice on each bullet wound to remove the bullets, then unequip it and click each wound closed. These extra leg repairs are separate from removing the fork from his shoulder.

The final post-game achievement

On a narrow screen, scroll the table sideways to read all columns.

One additional achievement brings the reference total to 49.
AchievementWhenRequirement
You've found him!Post-game notebook replayFollow Kate’s letters through the alarm, bathroom, lab, attic and cellar; obtain the telescope and inspect the distant ruin’s window.

Use the secret-clip guide for the complete chain and the 6294 final box. Finishing the main ending alone does not perform this telescope interaction.

Replay and progress checks

  • Missed optional action: finish the game, choose Continue and use the notebook’s chapter selection. Revisit the named chapter and rebuild any prerequisite items before its missable action. Do not assume an item from your completed run is present in every replay.
  • Action completed but Steam reward missing: compare the in-game progress with Steam’s list and update the Steam installation. Rusty Lake published achievement-sync work on August 14 and further Steam API changes on September 1; those notices describe historical fixes, not a guaranteed cure for every account.
  • Notebook or objects missing: this can be a save/build issue rather than a hidden achievement clue. The developer’s August 14 notice says not to reset a save with disappearing items; contact support. Use the launch and save-problem branches with your platform and version.

The release-era exercise guide does not establish a reliable repeated wrong-input pattern, and September’s notes changed its repeat behavior. Follow the scoped exercise conditions rather than treating every unsuccessful click as a new achievement requirement.
