What is Sudoku and why is it so popular?
Sudoku is a logic-based number puzzle that consists of a 9×9 grid with some cells filled with digits from 1 to 9. The goal of the game is to fill in the empty cells with the missing digits, so that each row, column, and 3×3 subgrid contains all the numbers from 1 to 9 without repeating. There is only one possible solution for each puzzle, and it can be found by using logic and deduction.
The history and origin of Sudoku
Although Sudoku is often associated with Japan, its roots can be traced back to ancient China, where a similar game called magic squares was invented. Magic squares are grids of numbers that add up to the same sum in every direction. In the 18th century, a Swiss mathematician named Leonhard Euler developed a variation of magic squares called Latin squares, where each row and column contains only one instance of each symbol. In the late 1970s, an American puzzle maker named Howard Garns created the modern version of Sudoku, which he called Number Place. He added the 3×3 subgrids and published his puzzles in a magazine called Dell Pencil Puzzles and Word Games. In 1984, a Japanese publisher named Nikoli introduced Number Place to Japan, where it became known as Sudoku, which means “single number” in Japanese. Since then, Sudoku has gained worldwide popularity and has been featured in newspapers, magazines, books, websites, apps, and TV shows.
The benefits of playing Sudoku for your brain and mental health
Sudoku is not only fun, but also good for your brain. Playing Sudoku regularly can help you improve your memory, concentration, logic, reasoning, and problem-solving skills. It can also stimulate your creativity, curiosity, and mental agility. Moreover, Sudoku can reduce stress, anxiety, and boredom by providing a relaxing and rewarding activity that challenges your mind. Studies have shown that playing Sudoku can also prevent or delay cognitive decline and dementia by keeping your brain active and healthy.
The different levels and variations of Sudoku puzzles
Sudoku puzzles come in different levels of difficulty, depending on how many cells are given at the start and how complex the logic required to solve them is. The most common levels are easy, medium, hard, and evil. Easy puzzles have more clues and less empty cells, while evil puzzles have fewer clues and more empty cells. Some websites and apps also offer variations of Sudoku puzzles that have different grid sizes (such as 6×6 or 12×12), shapes (such as diagonal or irregular), symbols (such as letters or colors), or rules (such as adding or subtracting). These variations can make the game more interesting and challenging for different types of players.
How to play Sudoku and solve the puzzles
Playing Sudoku is simple: you just need a pencil. and a paper, or a computer or a mobile device with a Sudoku app or website. You can start by scanning the grid and looking for the obvious clues, such as the cells that have only one possible digit. You can write that digit in the cell and eliminate it from the other cells in the same row, column, and subgrid. You can also use pencil marks to write down the possible candidates for each cell, and then use logic to eliminate the wrong ones. Here are some of the basic rules and tips for beginners:
The basic rules and tips for beginners
- Rule 1: Each row, column, and subgrid must contain all the digits from 1 to 9 without repeating.
- Rule 2: If a digit is already in a row, column, or subgrid, it cannot be in any other cell in that row, column, or subgrid.
- Rule 3: If a cell has only one possible digit, you can write it in the cell and cross it out from the other cells in the same row, column, and subgrid.
- Tip 1: Start with the easy puzzles and work your way up to the harder ones. The more you practice, the better you will get.
- Tip 2: Use pencil marks to keep track of the possible candidates for each cell. You can write them in the corners or the center of the cell, depending on your preference.
- Tip 3: Look for patterns and relationships among the digits and cells. For example, if two cells in a row, column, or subgrid have only two possible digits, and they are the same, then those digits cannot be in any other cell in that row, column, or subgrid. This is called a naked pair.
The common strategies and techniques for advanced players
As you progress to the harder puzzles, you will need to use more advanced strategies and techniques to solve them. Some of these include:
- Hidden pair: This is similar to a naked pair, but instead of two cells having only two possible digits, they have two possible digits that are hidden among other candidates in those cells. For example, if two cells in a row have the candidates 1, 2, 4 and 2, 4, 5 respectively, then they form a hidden pair of 2 and 4. You can eliminate those digits from the other cells in that row.
- X-wing: This is a technique that involves finding two rows (or columns) that have only two possible cells for a certain digit. For example, if rows 1 and 5 have only two possible cells for digit 7 in columns 3 and 7 respectively, then those four cells form an X-wing. You can eliminate digit 7 from the other cells in columns 3 and 7.
- Swordfish: This is an extension of the X-wing technique that involves finding three rows (or columns) that have only two possible cells for a certain digit. For example, if rows 1, 4, and 7 have only two possible cells for digit 9 in columns 2 and 6 respectively, then those six cells form a swordfish. You can eliminate digit 9 from the other cells in columns 2 and 6.
