Common Questions
Q. Do I need prior cryptography experience?
No. Each puzzle includes all the materials and hints you need. We start accessible and increase complexity over time. The first few months serve as your training ground.
Q. How difficult are the puzzles?
They're designed to take 1-3 hours for a focused solver. Some finish in 45 minutes; others savor them over a weekend. There's no timer, no leaderboard — just the satisfaction of cracking it.
Q. Do you ship internationally?
Currently we ship to the US, Canada, UK, and EU. International shipping is included in the subscription price. Delivery typically takes 7-14 days outside the US.
Q. What if I can't solve a puzzle?
The following month's envelope includes the previous solution in a sealed insert. Peek if you must. We won't judge. (Much.)
Q. Can I gift a subscription?
Yes. Email us at hello@inkbath.com with the recipient's address and we'll handle it. Gift subscriptions are available in 3, 6, or 12-month increments.
