Simple game rules
Sudoku is a logic puzzle played on a grid of 9×9 squares. This grid is further subdivided into nine smaller squares, each consisting of 3×3 cells. These smaller squares are often called ‘regions’ or ‘blocks’.
Rows: There are 9 horizontal rows in the grid. According to the rules of Sudoku, each number from 1 to 9 may appear only once in each row.
Columns: There are also 9 vertical columns in the grid. As with the rows, each number from 1 to 9 may only appear once in each column.
Blocks or regions: These are the nine 3×3 squares that together form the large 9×9 grid. In each of these 3×3 blocks, each number from 1 to 9 may only appear once.
When you start a Sudoku puzzle, some boxes are already provided with numbers. These are the ‘given’ figures. The player’s goal is to fill in the blanks according to the rules above.
The great thing about Sudoku is that there is only one unique solution to each puzzle, which can be achieved through purely logical reasoning. You don’t have to do any math or guess. If you work in a systematic way and pay close attention to the numbers already entered, you can find the solution. Believe us, it’s really easy to learn.
Progressive difficulty levels in sudoku
You can learn to play Sudoku at different levels. From very simple to very advanced. This means that Sudoku has a suitable level for everyone.
What determines the difficulty level?
The difficulty of a Sudoku puzzle is usually determined by two main factors: the number of numbers already given (the starting clues) and the types of logical techniques required to solve the puzzle.
Easy puzzles
These are ideal for sudoku beginners to start learning the game. They often have more given numbers and the relationships between the numbers are more direct and easier to find. These puzzles usually allow the player to quickly fill in multiple numbers without thinking too hard.
Average puzzles
These puzzles require a little more logical reasoning. There may be fewer numbers given and the player may need to use more advanced techniques to find the solution.
Difficult and very difficult puzzles
These puzzles often require more advanced strategies and techniques and are harder to learn. There may be fewer clues and the relationships between the numbers are often more subtle and complex.
Learning through progression
By starting with simpler puzzles, players can become familiar with the basic strategies of Sudoku. As they learn to become more skilled, they can move on to more difficult puzzles and learn new techniques. This gradual learning process allows players to build their skills without becoming overwhelmed.
Develop strategies
While beginners may focus on immediately visible solutions, such as finding rows, columns, or blocks where only one possible number fits, more experienced players will explore deeper strategies such as ‘naked twins’, ‘dot method’, and other techniques.
By starting at a lower level and gradually attempting more difficult puzzles, players can strengthen their understanding and skill in Sudoku, making it both challenging and rewarding.
No mathematical knowledge required
Not everyone is equally good at math, but you don’t need to. Sudoku does not require any mathematical knowledge to learn the game.
Numbers as symbols
In Sudoku, numbers are used, but not in their mathematical context. The numbers 1 to 9 can just as well be replaced by nine different symbols, colors, or letters. The point is that each of these nine unique elements only appears once in each row, column, and 3×3 block.
Logic over math
Sudoku is about logical reasoning and ruling out possibilities. For example, if a certain number already appears in a row and a column that intersects a specific box, you can conclude that that number cannot appear in that box again. No formulas, additions, multiplications, or other mathematical calculations are required.
Pattern recognition
One of the skills players develop while playing Sudoku is the ability to recognize patterns. By looking at the layout of the given numbers and the numbers you’ve already entered, you can often predict which numbers might go where, or which cells are most likely to be solved.
Accessible to everyone
Because Sudoku does not rely on mathematical calculations, it is accessible to people of all ages and backgrounds, even those who do not consider themselves “mathematical.” This makes it a universal game.
Training in logical thinking
Playing Sudoku can even help improve logical thinking skills, as you must continually form and test hypotheses and consider the consequences of each choice.

Encouragement
It is important to realize that everyone learns at a different pace. In the beginning, Sudoku is a race against the clock. What may be easy for one person at first may be challenging for another. The key word here is perseverance. Confidence grows with each completed Sudoku puzzle.
Variety
