Global Solution for Sudoku

Sudoku solving is often taught as a string of separate tricks. Zhong-Qi Ma takes a more systematic route: Global Solution for Sudoku sets out six basic rules and a notation for following the reasoning across a puzzle. The emphasis is not on supplying grids to fill in, but on making the solving process clear and repeatable.

A structured way to read a Sudoku grid

Ma’s approach considers the puzzle as a whole, then tracks how its numbers and arrangements interact. Special symbols mark the steps, giving the deductions a visual record that the author likens to annotations in chess. That structure can help readers follow not only what a move is, but how the reasoning develops from one step to the next.

From approachable puzzles to tougher challenges

The book works through classic Sudoku examples at different levels of difficulty. Later discussions include two particularly difficult puzzles designed by Arto Inkala, with their solving processes presented step by step. These worked examples let readers see the method applied to grids where progress may be less obvious.

For curious puzzle solvers

Written for people interested in Sudoku, the book introduces its method without requiring advanced mathematical training. It may suit readers who enjoy studying the logic behind a solution as much as completing the puzzle itself—and who would like a more organized alternative to relying on scattered tips or guesswork.

For a focused look at classic Sudoku logic, Ma offers a distinctive framework to read, follow, and try for yourself. 📚
