To play Sudoku, fill a 9x9 grid so that each row, each column, and each of the nine 3x3 sub-grids (called "boxes") contains all the numbers from 1 to 9 without repeating any number. This is done using logic and process of elimination without guessing.
Basic Rules
- Use numbers 1 to 9.
- Each number must appear exactly once in each row.
- Each number must appear exactly once in each column.
- Each number must appear exactly once in each 3x3 box.
- Don't guess; only place numbers that can be logically deduced.
Playing Steps
- Look for the easiest placements where only one number is possible.
- Identify which numbers are missing from each row, column, or box.
- Use elimination by checking rows, columns, and boxes to narrow down where numbers fit.
- Keep moving around the grid instead of focusing on one area when stuck.
- Re-evaluate the puzzle after every placement to find new logical placements.
Tips
- Use pencil marks or notes to indicate possible numbers for cells.
- Practice scanning rows, columns, and boxes to spot opportunities.
- Patience and logic are key; guesswork is discouraged.
This approach allows you to logically fill in every cell with the correct number, leading to completing the puzzle successfully.
