Sudoku is a onerule puzzle game that can be either satisfyingly simple or deceptively difficult.
Step 1:
Understand the pattern of a sudoku puzzle. Cells where an individual number goes are called squares; squares are then sectioned off in groups of nine to create boxes. A sudoku puzzle has a total of 81 squares, and nine boxes. They create a threeboxbythreebox grid.
Tip
Many sudoku puzzles have dark lines separating the nine threesquarebythreesquare boxes for easy identification.
Step 2:
To solve a sudoku puzzle, each row of nine squares must contain the numbers 1 through 9. Each column must also contain the numbers 1 through 9, and each box must contain the numbers 1 through 9. No row, column, or box may repeat any number.
Step 3:
Start with an easy puzzle, and work your way up to successively more difficult puzzles. Many squares will already be filled in, no matter the puzzle level. Based on those filled in squares, using logic and the process of elimination, begin deducing which numbers fit in the empty squares.
Tip
Any puzzle that has one single solution will have at least 17 squares already filled in.
Step 4:
Use crosshatching, the process of figuring out where a number fits by eliminating possibilities based on numbers in the other squares in the same row, column, and box. For example, if the topmiddle box contains no number 8, and the other boxes along the top row of the sudoku board contain 8s in the first and second rows, process of elimination dictates the 8 in the uppermiddle box must be in the third row.
Step 5:
Once you’ve solved one square by crosshatching, use the technique to fill in as many squares in that single box as you can.
Step 6:
Once you have exhausted one box, either by filling it in completely or running out of discoverable solutions, continue to the next box, then the next box, until you’ve gone through all nine boxes.
Step 7:
Typically, by doing simple crosshatching you will fill in several squares. Once you’ve gone through all the boxes, return to the box you started with and repeat the process, as it’s likely there are now more available solutions.
Step 8:
After crosshatching, try the counting method. Look at a single square, and count 1 through 9 through all possibilities, marking off ones that are immediately disqualified because it already appears either in the same box, the same column, or in the same row as the empty square.
Step 9:
For most easy puzzles, these simple techniques should be sufficient to help you complete the puzzle. As you practice, you’ll be able to develop your own strategies and think ahead, which will help you progress on to more difficult puzzles.
