What is sudoku ?
Sudoku is a puzzle game that involves filling in a grid of numbers so that each column, row, and region contains all the digits from 1 to 9. The grid is divided into nine smaller grids called "regions," and each region must also contain the digits 1 through 9.
To solve a sudoku puzzle, you must use logic and eliminate possibilities until you determine the correct digits for each empty cell. This process can be challenging, as there may be multiple possible solutions for any given cell, and it is up to you to determine which one is correct.
Sudoku is a great way to exercise your brain and improve your problem-solving skills. It is suitable for players of all ages and can be enjoyed by people of all skill levels, from beginners to experts. Whether you are a seasoned sudoku player or just starting out, there is always a new puzzle waiting to be solved. So, this is the brief explanation of sudoku.

How to solve easily a sudoku at the easy level ?
Solving a sudoku puzzle at the easy level is a fun and rewarding activity that can help improve your logical thinking and problem-solving skills. Here is a step-by-step guide to solving an easy sudoku puzzle:
- Start by looking for cells that have only one possible value. If a cell can only be filled with one number, then it must be that number.
- Look for rows, columns, and 3x3 boxes that contain only one possible cell for a particular number. If there is only one cell in a row, column, or box that can hold a specific number, then that cell must contain that number.
- Look for cells that are "locked" in. If a cell can only contain one number, and that number must go in that cell, then all other cells in the same row, column, and box can be eliminated as possibilities for that number.
- Repeat steps 1-3 until the puzzle is solved, or until you reach a point where you cannot make any more progress using these methods.
- If you get stuck, try using the following techniques:
- Looking for "naked pairs" (two cells in the same row, column, or box that contain only the same two numbers as possibilities)
- Looking for "hidden pairs" (two numbers that can only go in two specific cells in the same row, column, or box)
- Using "crosshatching" (eliminating possibilities by examining the intersections of rows and columns)
Remember, sudoku is a game of logic and patience. Don't get frustrated if it takes you a while to solve the puzzle. Just keep trying different techniques and you will eventually find the solution!
What are the variants of sudoku ?
There are many variants of sudoku, each with its own unique twist on the classic puzzle. Here are a few examples:
- Mini sudoku: Mini sudoku puzzles are smaller than traditional sudoku puzzles, with a grid size of 4x4, 6x6, or 8x8. These puzzles are great for beginners or for those who want a quick mental break.
- Samurai sudoku: Samurai sudoku puzzles consist of five overlapping sudoku grids, with a total of 21 sub-grids. Solvers must fill in all the grids so that each row, column, and 3x3 box contains the numbers 1-9.
- Jigsaw sudoku: Jigsaw sudoku puzzles are similar to traditional sudoku, but the grid is divided into irregularly shaped "jigsaw" pieces. Solvers must fill in the grid so that each row, column, and jigsaw piece contains the numbers 1-9.
- Killer sudoku: Killer sudoku puzzles are a combination of sudoku and kakuro. Solvers must fill in the grid so that each row, column, and 3x3 box contains the numbers 1-9, but they must also follow the "cage" clues, which specify the sum of the numbers within a group of cells.
- Sudoku-X: Sudoku-X puzzles are traditional sudoku puzzles with an added twist: the diagonals must also contain the numbers 1-9.
- Greater than sudoku, also called Futoshiki: Greater than sudoku puzzles are traditional sudoku puzzles with the added constraint that the numbers in each cell must be greater than the numbers in the cells directly adjacent to it (horizontally, vertically, or diagonally).
These are just a few examples of the many variations of sudoku that are available. Whether you're a beginner or an experienced solver, there is a sudoku variant that will challenge and entertain you.
