What is Sudoku and Why is it Popular?
Sudoku is a puzzle game that consists of a grid of squares, usually 9 by 9, divided into smaller regions, usually 3 by 3. The goal is to fill in the empty squares with numbers from 1 to 9, so that each row, column, and region contains each number exactly once. The puzzle starts with some numbers already given in the grid, and the difficulty level depends on how many and which numbers are given.
The History of Sudoku
Sudoku originated from a mathematical concept called Latin squares, which was invented by a Swiss mathematician named Leonhard Euler in the 18th century. Latin squares are grids of symbols that follow the same rule as sudoku, but with any symbols instead of numbers. The modern version of sudoku was created by an American architect named Howard Garns in the late 1970s, and was first published in a magazine called Dell Pencil Puzzles and Word Games. The name sudoku comes from the Japanese word for "number place", and was popularized by a Japanese publisher named Nikoli in the 1980s. Sudoku became a global phenomenon in the early 2000s, when it was introduced to newspapers and websites around the world.
The Benefits of Sudoku
Sudoku is not only fun, but also beneficial for your brain. According to some studies, sudoku can help you improve your cognitive abilities, such as attention, memory, logic, reasoning, and problem-solving. Sudoku can also help you reduce stress, enhance your mood, and prevent mental decline as you age. Sudoku is suitable for people of all ages and backgrounds, as it does not require any mathematical or language skills. Sudoku can also be played anywhere and anytime, as it only requires a pencil and paper or a digital device.
What is 4x4 Sudoku and How to Play It?
4x4 sudoku is a variation of sudoku that has a smaller grid of 4 by 4 squares, divided into four regions of 2 by 2 squares. The goal is to fill in the empty squares with numbers from 1 to 4, so that each row, column, and region contains each number exactly once. The puzzle starts with some numbers already given in the grid, and the difficulty level depends on how many and which numbers are given.

The Rules of 4x4 Sudoku
The rules of 4x4 sudoku are the same as the rules of regular sudoku, except that you use numbers from 1 to 4 instead of numbers from 1 to 9. Here are the rules in detail:
Fill in the empty squares with numbers from 1 to 4.
Each row must contain each number from 1 to 4 exactly once.
Each column must contain each number from 1 to 4 exactly once.
Each region must contain each number from 1 to 4 exactly once.
You cannot change or erase the numbers that are already given in the grid.</. The Strategies of 4x4 Sudoku
4x4 sudoku is easier than regular sudoku, but it still requires some logic and strategy to solve. Here are some tips to help you solve 4x4 sudoku puzzles:
Start with the obvious. Look for rows, columns, or regions that have only one empty square, and fill it in with the missing number.
Use elimination. Look for rows, columns, or regions that have only two empty squares, and see what numbers are possible for each square. If one of the squares can only have one possible number, fill it in. If both squares can have the same number, eliminate that number from the other squares in the same row, column, or region.
Use pencil marks. If you are not sure about a number, you can write it in a small font in the corner of the square as a reminder. This can help you keep track of the possible numbers for each square. However, be careful not to clutter the grid with too many pencil marks, as this can make it harder to see the clues.
