Sudoku Puzzles ‘Guru’ Book Review:
Because of its ability to keep our minds alert and occupied, and sharpen our brains, Sudoku proves to be a challenging puzzle. Sudoku as a game has found an important presence in our lives. The unfilled numbers on empty boxes accompany us to long travels, buses and train rides, and kick-start our mornings or lighten up our evenings.
At the same time, a few of us shriek away from this amazing game of numbers: perhaps because of the horrible feeling of not being able to complete the game once started, or because of a fear of intimidating numbers, or just the lack of confidence due to not knowing the game ‘well enough’. True, the existing Sudoku puzzle books come with solutions, and the newspapers publish the puzzle solutions the next day; but these are simply not enough.
What is the use of having the solution right in front of you, when you do not know how to arrive at that solution? Like any Math problem or a journey, it is the road leading to the destination that is more important than the destination itself. What fosters one’s confidence is the right guidance showing the way to reach the solution. It is this guidance that makes all the difference. And it is this guidance that makes “Sudoku Puzzle Guru” by Divyang Pandit a unique book: unlike most books on Sudoku puzzles, this book is a step-by-step guide which incorporates some excellent puzzle solving techniques. It is one-of-its-kind due to the methodological approach adopted to solve Sudoku puzzles.
The book begins with the meaning and nature of Sudoku and shares the author’s personal Sudoku journey. The second section of the book is divided into the primary and secondary methods that provide a steady progression towards mastery of Sudoku. The book also includes three different levels of practice puzzles.
A definitely must buy for those who are already interested in the game and want to master it, as well as the absolute beginners!

Q-6) What the name Sudoku means?
In Japanese, “Su = Number”, “doku = Single”. A puzzle using single numbers.
Q-7) What makes a given Sudoku puzzle simple or difficult to solve?
It primarily depends on how many digits are already given to start a puzzle. The more digits that are given in a puzzle upfront, the easier it is going to be to find the missing numbers. But fewer these given numbers are at the beginning, more brain power it will take to solve it.
Q-8) Do I need a large eraser to correct my guesses, at the beginning, when I am learning?
No. These “Guru” methods yield the missing correct digits only. You enter the missing digit only after you are 110% sure that it is the correct answer.
Q-9) What advise can you give to the people starting to learn the Sudoku now?
Remember, slow and steady wins the game. Practice makes you perfect. No one will know how fast you learned it, but everyone will notice how good you are solving it. Have plenty of patience and concentration in the beginning and avoid the most common error of duplicate numbers in a row, or a column or a cluster.
Q-10)And some more words of wisdom until you also become a “Guru” yourself.?
Select the shaded puzzles to assist you in easily recognizing cluster boundaries. Print a larger version of a puzzle, if available. Use various different color markers to learn the methods faster. Always count the given digits for a puzzle first and deduce how many are left to solve. Make a puzzle tracker table upfront for each puzzle, before you start. Welcome to Sudoku-land! And enjoy your journey.
