No walkthrough yet, and what comes instead

CHECKED 2026-11-14 · Guide

Quick answer

The game is not out, so a walkthrough would be invented. What exists now is method; the puzzle index and chapter one publish on launch day.

You searched for a walkthrough, and this site does not have one. Here is the honest reason, and what will exist instead.

No walkthrough, on purpose

The game unlocks on 9 December 2026 on Steam and 10 December 2026 per LEVEL5's own product page. It is not out. A chapter-by-chapter walkthrough of a game nobody has played is fiction, and several sites already publish exactly that.

You can check this yourself in under a minute: open any site claiming a full walkthrough, and look for a puzzle number higher than the ones in the official screenshots. If it has one, the site invented it.

Real guide content that does not require the game:

Publishing plan for launch day

This is the commitment, in order of what people search for:

PageWhenWhat it will contain
First chapter walkthroughDay onePuzzle numbers, locations, and the answer to each, behind a spoiler line
Puzzle indexDay one to week oneEvery puzzle with its number, type and hint count
Achievement listDay oneNames and conditions, from the Steam stats page
Hint coin mapWeek onePer-area coin counts, verified by playing
Town facilities tableWeek oneWhich puzzle upgrades which facility

The puzzle index is the big one. A Layton game's walkthrough is essentially an index of numbered puzzles, and building it means playing the game - there is no shortcut and no API for it.

Something now would be fiction

Because a wrong answer is worse than no answer, and because this series is unusually easy to fact-check. Puzzle numbering is sequential and printed on screen. A guide with a fake answer for puzzle 014 will be caught by the first person who reaches puzzle 014.

The same logic applies to chapter names, study topics and puzzle counts. Every one of those is visible on screen from the first hour of play, which means the market for invented guides closes on launch day.

Until December

  1. Read puzzle school - the method does not expire.
  2. Decide your platform with which version to buy, because pre-orders are already open on two of the four.
  3. Pre-order before 9 December if you want the eleven-track soundtrack.
  4. Play one of the older games so the puzzle vocabulary is already in your hands.

When the game is out, come back. This page becomes an index, and the walkthrough starts with the first puzzle rather than the last.
