How To Play Sudoku
Sudoku might look tricky at first, but it's actually a fun puzzle game anyone can enjoy. Let's break it down step by step, how to play sudoku for beginners!
Step 1: Understand the Grid
Sudoku is played on a 9x9 grid, divided into nine 3x3 smaller grids. Your goal is to fill in the grid with numbers from 1 to 9, making sure that each row, column, and smaller 3x3 grid contains every number exactly once.
Step 2: Start with What's Given
Look at the Sudoku puzzle. Some numbers are already filled in. These are your starting points. Let's say you see a '5' in a box. Check the row, column, and smaller grid it belongs to. Make sure there are no other '5's in those areas.
Step 3: Fill in the Blanks
Now comes the fun part! Start with the numbers 1 through 9. Look for a row, column, or smaller grid with fewer numbers filled in.
Ask yourself, "What numbers are missing?" Fill in those blanks, making sure you follow the rules—no repetition in rows, columns, or 3x3 grids.
Step 4: Use the Process of Elimination
If you're stuck, don't worry. This game is about logic, not luck. If a '6' can only go in one spot in a row, column, or 3x3 grid, put it there. As you fill in more numbers, it becomes easier to see where the remaining numbers should go.
Step 5: Check and Double-Check
Once you think you've filled in the entire puzzle, take a moment to check your work. Ensure that each row, column, and 3x3 grid has the numbers 1 through 9 with no repetitions.
How To Play Sudoku: Example
Sudoku puzzles come in different difficulty levels based on how many starting clue numbers are provided:
- Easy - Over 30 givens to start
- Medium - 26 to 29 givens initially filled
- Hard - 21 to 25 numbers provided initially
- Expert - Fewer than 21 pre-filled numbers
Example: Let’s walk through a medium-difficulty puzzle - an incomplete 9x9 grid:
Look at the entire grid and boxes, scanning for any patterns or themes that stand out initially. Here we see:
- Some columns/rows (like column 3) have several filled cells already
- Certain small boxes (like center-right) have no numbers filled in yet
- Note any patterns or things of interest that may help as you solve
Next, systematically check rows and columns for missing digits 1-9 without duplicates. For example:
- Row 1 needs 2,4,6,7,8,9 still.
- Column 9 needs 1,2,4,5,7.
Examine each 3x3 box for remaining options from 1-9 without repeats.
- The top left box still needs 2,4,7.
- The middle right box has no numbers yet.
Use logic and deduction strategies to fill cells:
- If a number fits one cell in a row/column, fill it.
- If a cell has just one option left for its box, fill it.
- Identify promising intersections.
Work slowly, double-checking. Scan the full puzzle before each step.
When deductions are exhausted but cells remain, logically guess between remaining options for a cell, then continue solving.
