Cómo es el juego de Sudoku?
Sudoku is a popular puzzle game that originated in Japan in the late 19th century. It has since become a global phenomenon, with millions of people enjoying its challenge and relaxation. But for those who are new to the game, what exactly is Sudoku, and how do you play it?
What is Sudoku?
Sudoku is a mathematical puzzle that requires logic and problem-solving skills to complete. The game is played on a 9×9 grid, divided into nine 3×3 sub-grids or "regions." Some numbers are already filled in, while others are blank. The objective is to fill in all the blank cells with numbers from 1 to 9, such that each row, column, and region contains each number only once.
The Rules of Sudoku
Here are the basic rules of Sudoku:
• Each number can only appear once in each row. This means that if a row already contains the number 5, for example, you cannot repeat that number in that row.
• Each number can only appear once in each column. This means that if a column already contains the number 3, for example, you cannot repeat that number in that column.
• Each number can only appear once in each region. This means that if a region already contains the number 8, for example, you cannot repeat that number in that region.
How to Play Sudoku
Here are the steps to play Sudoku:
- Start with the easiest clues: Begin by filling in the numbers that are already given in the puzzle. Look for rows, columns, and regions that have only one blank cell, and see if you can figure out which number should go in that cell.
- Use elimination to figure out which numbers can go in each cell: Look for rows, columns, and regions that already have a certain number in them. Use this information to eliminate that number from the remaining blank cells.
- Fill in the easy numbers first: Once you’ve eliminated some numbers from the blank cells, look for numbers that can go in those cells based on the clues given. Fill in the easy numbers first, and then move on to the harder ones.
- Use advanced techniques to solve the harder puzzles: As you progress to more challenging puzzles, you’ll need to use more advanced techniques, such as "nishing" (finding the shortest possible solution) and "forcing" (forcing a particular number to go in a particular cell).
