What is Sudoku and How to Play It
Sudoku is a logic-based puzzle game that originated in Japan in the 1980s. The name sudoku comes from the Japanese words "su" (number) and "doku" (single), meaning "single number". The goal of sudoku is to fill a 9x9 grid with numbers from 1 to 9, such that each row, column, and 3x3 box contains each number exactly once. There is only one solution for each sudoku puzzle, and it can be found by using logic and deduction, without guessing or arithmetic.
The Rules of Sudoku
The rules of sudoku are simple and easy to understand. Here are the basic steps to follow:
Look at the given numbers (also called clues or givens) in the grid. These numbers will help you fill in the empty cells.
Scan the rows, columns, and 3x3 boxes to find where you can place a number. A number can only go in a cell if it does not already appear in the same row, column, or box.
Use a pencil or a pen to write the number in the cell. If you are not sure, you can use pencil marks (also called candidates or notes) to write small numbers in the corners of the cell, indicating the possible values for that cell.
Repeat steps 2 and 3 until you fill in all the cells or get stuck.
If you get stuck, you can use some advanced techniques (see below) to eliminate more candidates or find hidden patterns.
If you fill in all the cells correctly, you have solved the puzzle. Congratulations!

The Basic Techniques of Sudoku Solving
The basic techniques of sudoku solving involve scanning the grid and looking for numbers that are easy to place. These techniques are usually enough to solve easy and medium puzzles. Here are some of the basic techniques of sudoku solving:
Naked Single: This is when a cell has only one possible candidate. For example, if a cell is the only one in its row, column, or box that can have a 5, then you can place a 5 in that cell.
Hidden Single: This is when a number can only go in one cell in its row, column, or box, even though there are other candidates in that cell. For example, if a 5 can only go in one cell in its box, even though that cell has other candidates, then you can place a 5 in that cell.
Naked Pair: This is when two cells in the same row, column, or box have the same two candidates. For example, if two cells in the same row have only 2 and 7 as candidates, then you can eliminate 2 and 7 from the other cells in that row.
Hidden Pair: This is when two numbers can only go in two cells in the same row, column, or box, even though there are other candidates in those cells. For example, if 2 and 7 can only go in two cells in the same box, even though those cells have other candidates, then you can eliminate the other candidates from those cells.
The Advanced Strategies of Sudoku Solving
The advanced strategies of sudoku solving involve finding more complex patterns and relationships among the numbers and candidates. These strategies are usually needed to solve hard and expert puzzles. Here are some of the advanced strategies of sudoku solving:
X-Wing: This is when two rows (or columns) have only two possible cells for a number, and these cells form a rectangle. For example, if two rows have only two possible cells for a 5, and these cells are in the same columns, then you can eliminate 5 from the other cells in those columns.
Swordfish: This is an extension of the X-Wing, where three rows (or columns) have only three possible cells for a number, and these cells form a shape like a fish. For example, if three rows have only three possible cells for a 5, and these cells are in the same columns, then you can eliminate 5 from the other cells in those columns.
XY-Wing: This is when three cells form a triangle, and each cell has only two candidates. For example, if one cell has 2 and 3, another cell has 3 and 4, and another cell has 2 and 4, then you can eliminate the common candidate (in this case, 4) from the cells that see all three cells.
Coloring: This is when you assign different colors to the candidates of a number, based on whether they are in the same row, column, or box. For example, if you color all the 5s in the grid with red or blue, then you can eliminate any 5 that sees both colors.
