What is Sudoku?
Sudoku is not just any ordinary number puzzle; it is a mental workout that engages your logical thinking and problem-solving skills. The goal is simple – fill a 9×9 grid with numbers from 1 to 9, making sure each row, column, and 3×3 section contains all the digits without repetition. Sounds easy, right? Well, let’s see about that!
The Basics of Sudoku:
Before we dive into the world of complex strategies and techniques, let’s master the basics. Sudoku puzzles usually come with a few numbers filled in to get you started. Your job is to use logic and deduction to fill in the remaining squares. Sounds easy, but don’t be fooled. Sudoku is all about careful analysis and careful consideration of the possibilities.
Strategies to Solve Sudoku:
Now, let’s get into the meat of solving Sudoku puzzles. Brace yourself, for we’re about to unleash some killer strategies. The process of elimination is your best friend here. Crosshatching allows you to narrow down your options by eliminating numbers that already exist in rows or columns. Box/Line Reduction involves analyzing the overlapping regions to eliminate possibilities. And finally, the candidate list technique helps you keep track of numbers that could potentially fit in each square.
