Introduction
The topic of a Sudoku solving method is easier to understand when you approach it with a clear method instead of relying on instinct alone.
This guide explains an ordered workflow and shows how to use these ideas in a practical way while solving real Sudoku puzzles.
The goal is to scan the grid from simple singles to advanced eliminations, so every step should remain logical, readable, and easy to repeat.
Use the examples as a way to slow down, observe the grid, and understand why each move is valid.
Why a search order matters
A search order helps you spend less energy and makes your solving more repeatable.
In practice, this means looking at the grid carefully and connecting the visible information with the candidates that are still possible.
Do not rush this step: one accurate elimination is more valuable than several uncertain moves.
After each placement or elimination, update the affected rows, columns, and blocks before continuing.
Used consistently, this part of the method helps you scan the grid from simple singles to advanced eliminations.
Initial grid check

Recommended operating order
The recommended order starts with simple placements and gradually moves toward candidate eliminations.

- observe the grid and identify the most promising areas;
- check Naked Single and Hidden Single;
- update candidates after every placed number;
- look for Naked Pair and Hidden Pair;
- check Pointing and Claiming;
- look for any Naked Triple;
- move to X-Wing and Y-Wing only if the previous techniques are not enough;
- after every important placement or elimination, return to the simpler techniques.
Do not rush this step: one accurate elimination is more valuable than several uncertain moves.
Summary
The key idea is that a Sudoku solving method becomes much easier when you follow a consistent solving method.
Remember the practical goal: scan the grid from simple singles to advanced eliminations.
Start from the simplest checks, keep your candidates clean, and only move to advanced reasoning when the grid really requires it.
