What is Sudoku and Why is it So Popular?
Sudoku is a logic-based number puzzle game that originated in Japan. The name sudoku comes from the Japanese words "su" (number) and "doku" (single). The goal of sudoku is to fill a 9x9 grid with numbers from 1 to 9, so that each row, column, and 3x3 box contains each number only once. There are many variations of sudoku, such as irregular sudoku, killer sudoku, or wordoku, but the basic rules are the same.

The History of Sudoku
Sudoku was invented by Howard Garns, an American architect and puzzle constructor, in 1979. He called it "Number Place" and published it in a magazine called Dell Pencil Puzzles and Word Games. The puzzle became popular in Japan in the 1980s, where it was renamed sudoku by Nikoli, a Japanese puzzle publisher. Nikoli also introduced some innovations to the puzzle, such as the symmetrical arrangement of the given numbers and the restriction of 30 clues per puzzle. Sudoku gained worldwide popularity in the 2000s, when it was featured in newspapers, magazines, books, websites, and apps around the world.

How to Play Sudoku and Improve Your Skills
Now that you have downloaded a sudoku game for your device, you might be wondering how to play it and improve your skills. Sudoku is a game that can be enjoyed by anyone, regardless of age or skill level. However, it can also be challenging and frustrating at times. Here are some tips on how to play sudoku and improve your skills:
Tips for Beginners
If you are new to sudoku, here are some tips to help you get started:
Start with easy puzzles. Easy puzzles have more clues and less empty cells, which makes them easier to solve. They will help you get familiar with the rules and the logic of sudoku.
Use pencil marks or notes. Pencil marks or notes are small numbers that you can write in the corners of the cells to indicate the possible candidates for that cell. They will help you keep track of the numbers and eliminate the wrong ones.
Use the process of elimination. The process of elimination is the basic technique of sudoku. It involves looking at the rows, columns, and boxes, and eliminating the numbers that cannot go in a certain cell based on the clues. For example, if a row has 1, 2, 3, 4, 5, and 6 already filled in, then the remaining cells in that row can only be 7, 8, or 9.
Look for singles and hidden singles. Singles are cells that have only one possible candidate left after eliminating the others. Hidden singles are cells that have only one possible candidate left in a row, column, or box, even if there are other candidates in that cell. For example, if a cell has 2, 4, and 8 as candidates, but 2 and 4 are already present in the same row or column or box, then that cell must be 8.
Check your work. Before filling in a number in a cell, make sure that it does not violate the rules of sudoku. Check that the number is not already present in the same row, column, or box. If you make a mistake, use the undo or erase function to correct it.
Tips for Advanced Players
If you are an experienced sudoku player, here are some tips to help you tackle harder puzzles:
Use advanced techniques. Advanced techniques are more complex and sophisticated methods of solving sudoku puzzles. They involve finding patterns and relationships among the numbers and the cells. Some examples of advanced techniques are naked pairs, hidden pairs, pointing pairs, box-line reduction, x-wing, swordfish, and coloring.
Learn from experts. Experts are people who have mastered sudoku and can solve any puzzle with ease. You can learn from them by watching their videos, reading their blogs, or joining their forums. You can also challenge yourself by trying to solve their puzzles or competing with them online.
Practice regularly. Practice makes perfect. The more you play sudoku, the more you will improve your skills and speed. You can practice by playing different types of puzzles, such as classic sudoku, irregular sudoku, killer sudoku, or wordoku. You can also practice by playing different difficulty levels, from easy to expert.
