How is a medium Sudoku different from an easy one?

Medium Sudoku puzzles have fewer starting numbers and require more advanced techniques beyond just finding obvious single candidates. You'll need to start looking for hidden singles and pairs.

What are 'hidden singles' in Sudoku?

A hidden single occurs when a specific digit (like a '7') can only logically be placed in one cell within a given row, column, or 3x3 box, even if that cell has other possible candidates.

How many numbers are usually given in a medium Sudoku?

While there's no strict rule, medium Sudoku puzzles typically provide between 26 and 31 given numbers. This is enough to require strategy but not so few that it becomes overly difficult.

Understanding Medium Sudoku Rules

The core rules of Sudoku remain the same, regardless of difficulty. Your goal is to fill a 9x9 grid so that each column, each row, and each of the nine 3x3 subgrids (also called boxes or regions) contains all of the digits from 1 to 9, without repetition. A medium Sudoku puzzle will typically come with a set number of pre-filled cells (known as givens), fewer than an easy puzzle but more than a hard one. This means you'll need to employ a more robust set of techniques to deduce the placement of the missing numbers.

Strategies for Medium Sudoku Success

Medium Sudoku puzzles invite a variety of logical techniques. While basic scanning for single candidates in rows, columns, and boxes (often called 'naked singles') is still fundamental, you'll often need to look for more advanced patterns. 'Hidden singles', where a number can only fit in one specific cell within a row, column, or box, become crucial. As you progress, you might start noticing 'naked pairs' or 'hidden pairs' – two cells that must contain a specific pair of numbers, allowing you to eliminate those numbers from other cells in the same row, column, or box. Don't be discouraged if a puzzle seems tough initially; persistence and careful observation are key. Think of the methodical approach needed to plan a visit to the Alamo – consistency pays off!

Applying these techniques systematically will help you uncover the solution. The satisfaction of completing a medium Sudoku puzzle, especially after a long day in the Texas heat, is immense.
