Many beginners make the mistake of guessing when stuck on a Sudoku puzzle. But great players know: Sudoku is a game of logic, not luck. In this post, we'll teach you how to solve Sudoku without guessing, using reliable strategies that boost accuracy and confidence.

🤯 Why You Should Avoid Guessing

Guessing leads to dead ends and frustration. It breaks the logical flow of the game and often results in messy puzzles. Instead, follow these methods to solve smarter:

🧠 1. Use the Cross-Hatching Technique

Look at rows and columns that intersect a 3x3 box. If a number appears in two out of three rows or columns, it must fit in the third.

🔢 2. Find Hidden Singles

A hidden single is a number that appears only once in a row, column, or box—even if the cell has multiple pencil marks. It's a guaranteed placement.

🔍 3. Apply the "Candidate Lines" Strategy

If a number can only appear in a certain line within a box, it cannot appear in the same line outside that box. This helps eliminate options logically.

🧩 4. Master the Naked Pair/Triple Technique

If two cells in a row or box contain the same two candidates, those numbers must go there—and can be eliminated from the other cells in that unit.

🧭 6. Start with Easier Sections

Work on boxes, rows, or columns that are more filled in first. The fewer blanks, the easier it is to apply logic.
