How to unlock the Tattoo Studio (Inkwell):
- Reach Day 7 or later.
- Head Outside and pick “Walk around the neighbourhood”.
- The next walk after Day 7 you’ll spot the INKWELL neon sign on a side street, that opens the studio for you.
After that the Tattoo Studio shows up as its own pin on the Downtown map and the Red Light District entrance.
If you miss it, on Day 10 you’ll also get an anonymous SMS pointing you toward Inkwell as a backup hint.
