The alchemy boxes take nine clicks in this order:
right, right, right, left, right, left, right, right, left
Enter it exactly. There is no partial credit and no feedback until the ninth click lands.
Where it is
Day 3, during Assisting in Alchemy, in the same stretch as the cabinet code 6294.
You will need it twice
Like the attic chest stars, this sequence comes back in the post-credits route for "You've found him!" — it is step four of eight. Record it now rather than replaying Day 3 to read it again.
The full set of values that route needs:
| Step | Value |
|---|---|
| Day 1 clock | 4:05 |
| Day 2 bathing tiles | Aleksandra, bath, suitcase, severed hand |
| Day 3 alchemy boxes | right ×3, left, right, left, right ×2, left |
| Day 1 attic chest stars | 4 2 3 |
| Day 3 cabinet | 6294 → telescope |
Full route on the "You've found him!" page.
Other Day 3 interactions in the same room
Animal Testing. You are asked to test the elixir. Give it to the parrot.
Seasoning to Taste. Kill the fly near the cake with the knife, then drop it into the soup.
Furniture Secrets. Under the kitchen table, click the second leg from the left for a hidden note.
