Professor Layton and the New World of Steam: All Puzzles

This will be the complete list of puzzles in Professor Layton and the New World of Steam — every puzzle by number, with its chapter, location and picarats, and a link to its own hint-by-hint page.

Before launch

The game isn’t out yet, so there’s nothing to list. We don’t publish guessed or placeholder puzzles: each entry goes up only once its answer has been checked in the game. The list will start filling up after the game unlocks on December 9, 2026 in the Americas and Europe (December 10 in Japan). Exact times are on the release date page.

What we know about the puzzles so far

• More than ever. LEVEL-5 says this game has the most puzzles in the series. The exact count hasn’t been announced, so we won’t guess.
• New designers. The puzzles are by QuizKnock, a Japanese quiz and knowledge group led by quiz champion Takushi Izawa.
• Hidden puzzles are tucked around Steam Bison for you to discover while exploring.
• Town-building puzzles. Some puzzles help upgrade the town’s facilities as you solve them.
• Mystella keeps track of the puzzles you haven’t solved yet.
• Daily puzzles arrive every day for more than a year after launch. They’ll have their own list.

What each puzzle page will include

1. A short description of the puzzle in our own words — no copied text or screenshots.
2. Three hints, each a little stronger than the last.
3. The answer, hidden until you open it.
4. A step-by-step explanation of why it works.
5. Where to find the puzzle, and links to the puzzles before and after it.
