Essential Sudoku Tips for Medium Difficulty
Here are five crucial tips to help you conquer medium Sudoku puzzles, whether you're playing at a cafe in Greenwich Village or on the subway:
- Scan Rows, Columns, and Boxes Systematically: Always start by looking for numbers that are already present in a row, column, or 3x3 box. Identify cells where a specific number can only go in one place (a 'naked single').
- Utilize Candidate Marking (Penciling In): For medium puzzles, it's essential to mark potential candidates (possible numbers) in empty cells. This visual aid helps you spot patterns and eliminations more easily.
- Look for Pairs and Triples: As you mark candidates, look for cells within the same row, column, or box that share only two possible candidates (naked pairs) or three (naked triples). These can help eliminate those candidates from other cells in the same unit.
- Apply Hidden Singles and Pairs: Sometimes a number can only go in one specific cell within a row, column, or box, even if that cell has other candidates. This is a hidden single. Similarly, a hidden pair exists when two numbers can only go in two specific cells within a unit.
- Don't Guess – Deduce: Resist the urge to guess. Every move should be based on logical deduction. If you find yourself guessing, take a step back and re-examine the grid for missed opportunities or apply a technique you haven't used yet.
