Sudoku Techniques
If you are new to Sudoku puzzles, it might seem overwhelming at first. But with some practice and patience, you can learn the techniques and tricks to solve even the most difficult puzzles. Here are some basic techniques you can use to solve this Hard Sudoku:
- Elimination: Look for squares that have only a few possible digits left. If a digit appears in the same row, column, or sub-grid, you can eliminate it as a possibility for other squares in that line or box.
- Crosshatching: Look at each row and column and cross out digits that already appear in that row or column. This technique can help you identify where a digit might be missing.
- Block and Column Interactions: Look for groups of digits that only appear in one block or column. If you can identify which square in that block or column must hold that digit, you can eliminate it as a possibility for other squares.
- Naked Pairs/Triples/Quads: Look for pairs, triples or quadruples of squares in which only the same two or three or four digits are possible. This technique allows you to eliminate those digits as possibilities for other squares in the same row, column, or sub-grid.
- X-Wing: Look for pairs of rows or columns in which only two squares in each line can hold a certain digit. If those squares form a rectangle shape in the grid, you can eliminate the possibility of that digit in the corresponding squares in the other row or column.
These are just a few basic techniques to get you started. As you practice more, you will find your own methods and strategies to approach each puzzle.
