What is Sudoku and why is it popular?
Sudoku is a logic-based number puzzle that originated in Japan in the 1980s. The goal of Sudoku is to fill in a 9x9 grid with digits from 1 to 9, such that each row, column, and 3x3 subgrid contains each digit exactly once. There is only one solution for each puzzle, and it can be found by using logic and deduction, without guessing or arithmetic.
Sudoku is popular because it is simple to learn, but challenging to master. It appeals to people of all ages and backgrounds, as it does not require any language or mathematical skills. It also provides a satisfying sense of accomplishment when you solve a puzzle, as well as a relaxing and enjoyable way to pass the time.
The basic rules and tips of Sudoku
Here are some of the basic rules and tips of Sudoku that you should know before you start playing:
You can only use the numbers 1 to 9 in each cell.
You can only use each number once in each row, column, and 3x3 subgrid.
You should avoid trying to guess the solution to the puzzle, as it can lead to errors and frustration.
You should use the process of elimination as a tactic instead, by looking for cells where only one number can fit, or where a number can be ruled out based on the existing numbers.
You should use cross-hatching and penciling in techniques to help you find and mark the possible candidates for each cell.
The benefits of playing Sudoku regularly
Playing Sudoku regularly can bring many benefits to your brain, such as:
Improving your concentration, focus, and attention span.
Enhancing your memory, logic, and problem-solving skills.
Stimulating your creativity and lateral thinking.
Reducing your stress and anxiety levels.
Preventing cognitive decline and dementia.
