How to Solve Advanced Dodoku: Free 8-Page Guide (PDF)

Stuck on an Advanced Dodoku? This free guide shows the way through.

Advanced Dodoku puzzles start with only 43 to 49 of their 144 cells filled in, and the easy moves run out early. This short guide teaches the five moves that solve them, in the order to use them. Every example comes from one real puzzle: Dodoku Halloween Edition, Advanced, Puzzle #19.

What's inside

• The rules in one minute, plus a simple map for finding your way around the 12x12 grid
• A pencil-mark layout that keeps twelve digits tidy in a small cell
• Five moves, each shown on the same puzzle: find the only place, find the only digit, box and line, pairs, and the two-choice test
• A step-by-step solving routine, and what to expect from the hardest puzzles

The details

• One PDF, 8 pages, 5.5 x 8.5 inches. It prints two to a sheet of letter paper.
• Puzzle #19 is printed in the guide, so you can follow along without the book.

Every Advanced puzzle in the Dodoku books was checked with exactly the moves in this guide. Want puzzles to practice on? Dodoku Halloween Advanced has 50 of them.
