Volume three keeps the two-puzzles-per-variant structure while deliberately giving you a lighter and a tougher example of each rule system. The result is 150 original puzzles with constant changes in geometry and constraints.
For experienced solvers who want broad exposure to Sudoku variants with a built-in easy/hard pairing for every puzzle type.
Each variation begins with standard Sudoku logic and adds a new constraint, layout, or relationship. The challenge is to understand the extra rule and then use it as another precise source of deduction rather than as a reason to guess.
What you will find inside- 150 puzzles
- 75 different Sudoku variations
- Two puzzles of each type: one relatively easier and one relatively harder
- Outside, Multi/LOCO, Frame, Diagonal, Jigsaw, Jigsaw Combination, Consecutive, Non-Consecutive, Hyper/Windoku, Greater/Less, Odd-Even, TriDoku, and Killer
- Double, Triple, Flower, TwoDoku, Butterfly, and Sudoku Ring layouts
- Grid sizes from 6x6 to 16x16
- Combinations of multiple variant rules
- Print format: 7 x 10 inches
The best way to use a variations book is to pause at the rule explanation, solve a few examples carefully, and notice which new deductions become possible. The extra constraint should reduce possibilities; it should never require guessing.
The physical edition contains 150 puzzles across 136 pages in a 7 x 10 inches trim size. That format is part of the buying decision: compare it with the neighboring DJAPE volumes by quantity, difficulty, and working space rather than by title alone.
How this volume fits the DJAPE collectionThis volume is one part of the multi-volume Sudoku Variations library. Its role is to add a distinct set of constraints to the collection rather than repeat the discovery-oriented first volume.
This book is aimed at regular puzzle solvers who want a substantial, clearly defined collection and a dependable level of challenge rather than an assortment with unclear difficulty.
Originality: all puzzles in this volume are original to this book and are not reused in the other DJAPE puzzle books covered by this project.
Created by DJAPE, publishing original logic puzzles since 2005 and creator of the weekly Samurai Sudoku appearing in The Washington Post since 2006.
