HOW TO PLAY       

  • How to solve Sudoku mathematically? Actually, Sudoku is a logic-based game that doesn’t require any skill in maths or calculations. As the name Sudoku suggests itself, the number must be limited to a single occurrence.  
  • The game is played in a 9*9 matrix which contains digits between 1 to 9 in such a way that each column, row, and 3*3 block should be filled with each digit from 1 to 9 without repetition. 
  • Each number should appear only once in a row, column, or block.
  • The players have to fill in all the blank squares before the time ends. Three minutes are given to fill the matrix. 
  • Only 5 lives are given for a player. One life will lose if one wrong filling is done. If the player loses 5 lives, the player will lose the game.
  • The numbers the player wants to fill in will be given at the bottom of the table. The player can click on the number and then click on the assigned cell to fill in the number. 
  • If a number is filled in all the columns, rows, and blocks, that particular number will be disabled automatically at the bottom session.
  • The timer will be given at the top of the puzzle. The timer will show the remaining time to end the game.   


  • If a player fills in the correct number in a cell, he/she will score 5 points.
  • If a player fills in the correct numbers in a row, he/she will score 50 points.
  • If a player fills in the correct numbers in a column, he/she will score 50 points.
  • If a player fills the correct numbers in a sub-grid or box, he/she will score 50 points.
  • If the player fills in a correct answer in a cell, 2 seconds will be given extra.
  • If a player fills in a wrong answer in a cell, 1 life will be gone out of 5 lives given. Any row, column, or sub-grid containing the same number two times or more will be considered incorrect or wrong. 
  • The main goal of the player is to earn a higher score in order to defeat the opponent and win the game.


  Sudoku is one of the best online games, but somewhat difficult to play at the beginning because you want to focus on the row, column, and sub-grid at the same time. How to play Sudoku for beginners? Here are some tips to play Sudoku easily.

  • Begin with free online games or practice games to understand the game properly and get on track.
  • It will be easier to work out the solution if you first focus on the row, column, or sub-grid that contains five or more numbers.
  • Visually break the matrix into rows, columns, and sub-grids to focus on the game. This way you can evaluate which numbers are absent in the subsequent rows, columns, and sub-grids. 
  • While you are finalizing your result, make sure that the same row, column, and sub-grid is not having that particular number. 
  • Use the note-mode option to find out the correct answer. In the note-mode option, you can slightly note the possible answer before finalizing it.
  • When you are looking at a cell and finding more than one possible answer, use the elimination process to fill the gap.
