Light spoilers. This page names rooms, items and characters you meet, but keeps the story beats out of it.

This is the condensed version of the whole game — the spine of all three days on one page, with links out to the detailed day pages and individual puzzle solutions. Use it as a checklist on a second run, or as a way to find which day your problem lives in.

The route at a glance

Day 1 — Aldous's routine and the reunion

  1. Courtyard: stack the two tin cups by line count, pay the driver.
  2. Hallway: gather wood, oats, milk, pot, matches; cook the porridge to the recipe note.
  3. Bedroom: shape box → razor. Then the strict wake-up order — curtains, clock to 7:00, shave, clean the ear, feed the earlobe to the raven, key, berries, then bowl → porridge → spoon → berries.
  4. Bedroom: plug the insect's escape holes with berries, then kill it.
  5. Bedroom: copy the wardrobe figurine's poses for the exercises.
  6. Hallway: find three candles, light the chandelier in shape order, garden door opens.
  7. Hallway: dust the portraits until one falls, reassemble it, watch the NPC animations.
  8. Garden: arrange the flowers, herd three cockroaches with the directional tile, fit all three stone tiles.
  9. Garden: shake the baby basket for the randomised luggage code, then pack the case with no gap at the top.
  10. Evening: tea service — hot water → tea → milk → powder, sugar twice with a repair in between.
  11. Parlor: wine cabinet 1753, bottle reassembly, nine-button box, put out William's cigar fire, painting sequence, flower binary targets 2, 3, 7, 9, 13, 22, and the lullaby order.
  12. Attic: chest stars 4, 2, 3.

Day 2 — coffee, hunt, bath

  1. Roast the beans before throwing them on the stove.
  2. Feather to William's face, not his feet.
  3. Scrub the family portrait in the kitchen.
  4. Hunt: five targets, ten bullets, no misses.
  5. Look through the second-floor bathroom keyhole.
  6. Bathing tiles: Alexandra, the bathroom, the bathtub, the suitcase, the hand — sources give four picks or five depending on whether bathroom and bathtub count separately. Work from what the grid offers; the set is the same either way.
  7. Wipe the window after Alexandra is in the bath.
  8. Balcony: throw everything down.
  9. Cellar hole: magnet for the key → click again → sledgehammer the mouse when it returns.

Day 3 — alchemy

  1. Pet Rustie on the maid's lap; check the table leg in the servants' room, the one the cat hides behind.
  2. Alchemy boxes: right, right, right, left, right, left, right, right, left.
  3. Elixir to the parrot; fly into the soup.
  4. Evening: line the fish shadow up with the rightmost second-floor window, take the brooch from the frame beside William, pose him to match the dining room painting and pin it on him.
  5. Click the chandelier rope repeatedly before dinner starts.
  6. Night: once you have the fork, click Aldous's lower leg and treat the wound with it.

After the credits — the "You've found him!" route. The 6294 box is on that route, in the cellar, not in Day 3's normal flow; the telescope inside is its final step.

The four numbers worth writing down

Luggage case (Day 1 garden)randomised — shake the basket

All of these, with the context for each, are on the codes page.

Sequences that only accept one order

Three chains in the game reject a correct set of actions performed in the wrong order:

  • Waking Aldous — curtains, clock, shave, ear, raven, breakfast.
  • Serving tea — hot water, tea, milk, powder, then sugar twice.
  • The lullaby — James's eyes, moon, swaddling cloth, ring, necklace, lips, window clouds, Alexandra's eyes.

If one of those is not advancing, you almost certainly have the right idea and the wrong sequence.

Missable achievements

Most hidden achievements are tied to a specific day-block and disappear when the block ends. The ones that trip people up are the deliberate failures — botching the exercises, letting the goat ruin the bouquet, handing the champagne to the baby — because a competent playthrough skips all three. The full ordered list is on the hidden achievements page.
