What is Sudoku Guru - classic sudoku
Sudoku Guru is your go-to destination for the classic number puzzle, offering a clean and intuitive interface that lets you dive straight into the challenge. Whether you're a novice or an expert, there's always a new grid to conquer.
How to Play
Fill each 9x9 grid so that every row, column, and 3x3 subgrid contains the digits 1 through 9 without repetition. Simply tap or click an empty cell and select a number to place it; you can also use pencil marks to note possible candidates.
Tips for Playing
- Start by scanning rows, columns, and boxes for easy placements, especially where only one number is possible.
- Use pencil marks to track candidate numbers in each cell; this helps you spot hidden singles and pairs.
- Look for 'naked pairs'—two cells in a row, column, or box that contain the same two candidates, eliminating those numbers elsewhere.
- If stuck, focus on a single unit (row, column, or box) and systematically consider each number's possible locations.
- Take a break if you feel frustrated; a fresh perspective often reveals the next correct move.
