Sudoku is a popular logic-based number puzzle game that was first introduced in Japan in the 1980s. The game is played on a 9x9 grid, which is divided into 9 smaller 3x3 grids. The objective of the game is to fill in the grid with numbers from 1 to 9 in such a way that each row, column, and 3x3 grid contains each number exactly once.
To play Sudoku, start by looking for cells in the grid that have only one possible number. Once you have filled in all the cells that have only one possible number, move on to cells that have two or three possible numbers and try to eliminate possibilities based on the numbers already in the row, column, or 3x3 grid. Keep repeating this process until you have filled in all the cells in the grid.
Tips and Tricks
Here are some tips and tricks to help you succeed in Sudoku:
- Look for patterns - There are certain patterns that can help you solve Sudoku puzzles more quickly. For example, if you have two cells in a row or column that can only be filled with two numbers, those numbers can be eliminated from the other cells in the same row or column.
- Use the "pencil in" technique - If you are unsure about a number, use the "pencil in" technique to write down possible numbers in a cell. This can help you keep track of possibilities and eliminate incorrect choices.
- Work from different perspectives - Sometimes it can be helpful to look at the grid from a different perspective. For example, try looking at the grid from the perspective of a 3x3 grid to see if any numbers can be eliminated.
