What is Sudoku and How to Play It
Sudoku is a logic-based number-placement puzzle. In its simplest and most common configuration, sudoku consists of a 9x9 grid with numbers appearing in some of the squares. The object of the puzzle is to fill the remaining squares, using all the numbers 1-9 exactly once in each row, column, and the nine 3x3 subgrids that compose the grid (also called "boxes", "blocks", or "regions"). The puzzle setter provides a partially completed grid, which for a well-posed puzzle has a single solution.
To play sudoku, you need to use logic and deduction to find the missing numbers in the grid. You can start by looking for rows, columns, or boxes that have more given numbers. These areas will constrain the other empty cells within the same row, column, or box. You can also look for numbers that appear more often among the given numbers. For example, if you have five 9s already given and no 2s, then placing one of the four remaining 9s into the grid will usually be easier than placing one of the nine 2s.
Another technique to play sudoku is to look for single candidates, also known as naked singles. These are cells that can only have one possible number because all the other numbers from 1-9 are already present in the same row, column, or box. For example, if a cell is in a row that has all the numbers except 5, then that cell must be 5.
There are many other techniques to play sudoku, such as scanning, pencil marking, elimination, subsets, pairs, triples, x-wing, swordfish, etc. You can learn more about these techniques from online tutorials or books. The main thing to remember is that sudoku is a puzzle of logical deduction that uses the process of elimination to arrive at an unique solution.

The History of Sudoku
The history of sudoku dates back to an 18th century Swiss mathematician's game called "Latin Squares" (according to this article from ). Some of the first number puzzles to appear in newspapers were published in France in 1895. They were called "carré magique diabolique" ('diabolical magic square') and had similar rules as sudoku.
However, the modern version of sudoku as we know it today was created by an American named Howard Garns in 1979 and first published in a New York-based puzzle magazine as Number Place. They next appeared in 1984 in a magazine in Japan, where they acquired the name sudoku (abbreviated from suuji wa dokushin ni kagiru, meaning "the numbers must remain single"). In spite of the puzzle's popularity in Japan, the rest of the world remained largely unaware of sudoku until 2004, when a New Zealand judge named Wayne Gould introduced them to the British newspaper The Times. Since then, sudoku has become a global phenomenon, appearing in newspapers, magazines, books, websites, apps, and even TV shows and movies.

The Tips and Tricks to Solve Sudoku Faster
If you want to solve sudoku faster and better, you need to practice a lot and learn some tips and tricks that can help you speed up your solving process. Here are some of the most useful tips and tricks to solve sudoku faster:
Use pencil marks. Pencil marks are small numbers that you write in the corners or the center of the empty cells to indicate the possible candidates for that cell. They can help you keep track of the numbers that are already eliminated or confirmed in each row, column, or box. You can use pencil marks either manually or with the help of an app or a website that has this feature.
Look for single candidates. As we mentioned before, single candidates are cells that have only one possible number because all the other numbers are already present in the same row, column, or box. They are easy to spot and fill in. You should always look for single candidates first before moving on to more complex techniques.
Use scanning techniques. Scanning techniques are methods that allow you to eliminate or confirm numbers by looking at how they interact with each other in different rows, columns, or boxes. Some of the most common scanning techniques are cross-hatching, counting, pointing pairs, claiming pairs, hidden pairs, naked pairs, etc. You can learn more about these techniques from online tutorials or books.
Use advanced techniques. Advanced techniques are methods that involve more complex logic and reasoning to eliminate or confirm numbers. Some of the most advanced techniques are x-wing, swordfish, jellyfish, skyscraper, 2-string kite, unique rectangle, etc. These techniques are usually used for very hard puzzles that cannot be solved by simpler methods. You can also learn more about these techniques from online tutorials or books.
Check your work. Sometimes, you may make a mistake while solving sudoku that can lead you to a wrong solution or a dead end. To avoid this, you should always check your work as you go along. You can do this by verifying that each number appears exactly once in each row, column, and box; by checking if there are any contradictions or inconsistencies in your grid; or by using an app or a website that has a check feature.
By following these tips and tricks, you will be able to solve sudoku faster and better. However, remember that sudoku is not a race. The most important thing is to enjoy the game and have fun.
