Sudoku or originally called Number Place is a combination logic-based number sorting puzzle game. The object of the game is to fill in the numbers in a 9×9 grid such that each column, each row, and each of the nine 3×3 subgrids make up the main grid (also called the “box”, “block”). “, or “zone”) contain all the numbers 1 through 9. The puzzle is partially completed, and the player must continue to solve it by filling in numbers. Every well-established puzzle has a unique way of doing it.
History of NYT Sudoku
Sudoku is a Japanese noun, meaning “unique number”. Although the game was previously available in the US as Number Place, meaning “put the number in the right place”, the name Sudoku was given by Kaji Maki (鍜治 真起) and became a universal name. In the UK, within a few months, from a place not many people know about, it created a whirlwind, causing train passengers to miss the station and students to forget to do their homework.
The person who brought this game to the UK was a retired judge who worked in Hong Kong named Wayne Gould. He found a Sudoku magazine during his summer vacation in Japan. Although he did not know Japanese, he was very curious about the game. Gould figured out how to play the game by comparing the puzzle to the solution printed at the bottom of the magazine. Then he became so fascinated with it that he used his computer programming skills to write programs and create various puzzles.
How to play
A 9×9 grid must be filled with numbers in order to finish a NYT SUDOKU puzzle, and each column, row, and 3×3 square must have a number from 1 to 9. At the beginning of the game, certain squares on the 9×9 grid will be filled in. You must logically add the missing digits to the grid to finish it. Keep in mind that an action is wrong if:
- Any row can have several occurrences of the same 1 to 9 digit number.
- Any column in the range of 1 to 9 has several occurrences of the same number.
- Multiples of the same number can be found in any 33-grid from 1 to 9.
Tips to play SUDOKU better
Having trouble solving Sudoku problems because you’re just getting started? Or are you moving on to harder stages only to find that you’ve reached a dead end?
You’ll gain from using these Sudoku solving strategies in either situation.
Know where to start solving
When you first look at a new Sudoku puzzle, you might discover that you are unsure of where to begin.
The trickiest aspect of the grid placement can occasionally be the first digit.
There are a few things you should look for to make it simpler. You may also wish to avoid doing other things.
The first piece of advice is to search for rows, columns, or 33 blocks with the most provided digits.
The additional empty cells in the same row, column, or block will be constrained by these areas with more provided digits. Consequently, there will be fewer possibilities for the values that these cells could hold than there would be for other vacant cells.
Another approach related to this is to observe which numbers seem to emerge more frequently among the provided digits.
One of the four remaining 9s will typically be easier to place into the grid than one of the nine 2s. For instance, if you have a fresh Sudoku puzzle with five 9s already provided and no 2s.
Look for single candidates
Single candidates—also referred to as naked singles—occur when there is just one potential candidate for a given cell.
This is due to the fact that every other digit from 1 to 9 will have been eliminated by other grid numbers.
The Sudoku puzzle below shows that cell row 7, column 5, only has one choice, which is 1.
This is so that you can see how every other number from 2 to 9 appears in the same row, column, or 33 block.

This demonstrates the value of the earlier advice to start in places with a lot of supplied digits.
Improve your scanning methods.
Try not to concentrate on the entire Sudoku grid at once.
It is preferable to instead scan various rows, columns, and 3×3 blocks one at a time. By doing this, you’ll be able to see which parts are simpler and focus on those first.
Taking this advice a step further, you’ll also want to scan a few places at once to see how they interact while you’re feeling secure.
For instance, you will be able to see right away that a cell will be severely confined if you scan down a row and a column and note that they both contain a lot of numbers.
Try not to concentrate on one thing for too long.
A key component of efficient scanning is to avoid staring at one area of the grid for an extended period of time.
If you’re doing this, it’s likely that the area of the grid you’re concentrating on needs digits to be placed in other parts of the grid before it can be solved.
To choose which area can be worked on first, you must learn how to move your focus across the grid. Then you can return to the regions that are more challenging later.
Maintain the momentum
Sudoku is a momentum puzzle because some sections of the grid require the placement of additional digits elsewhere first before players can solve it again.
It will become clear that you can solve additional empty cells nearly in a cascade fashion once you begin adding numbers to the grid.
Because fresh digit placement may open new cells, it is crucial to scan along rows, columns, and within the 33 blocks.
Make use of pencil making
You can use the process of elimination to solve Sudoku puzzles by marking potential candidates in vacant cells.
Correct pencil marking will also help you improve your scanning methods and find both concealed and naked pairs.
Look for naked pairs
A naked pair occurs when two empty cells can only contain the same two possible candidates.
The Sudoku below features a highlighted example of a naked couple.
To solve sudoku, seek for naked pairings.
The only possible values for these two empty cells in row 8 are a 2 or a 3, which immediately eliminates 2s and 3s from the other vacant cells in the 33 block and the entire row.
This is so that you can’t possibly set a 2 or a 3 somewhere else in the box or row, regardless of which one is which.
Finding these kinds of naked pairs can be quite helpful since it can restrict the cells around them to the point where it makes room for a new digit to be added.
Don’t guess- use the process of elimination
Our last Sudoku tip is simple: Remember that Sudoku is a puzzle of logical deduction that uses the process of elimination to arrive at an unique solution.
That means you never have to guess when solving a Sudoku.
Instead, remain patient and think about the puzzle in front of you logically and carefully all while keeping the Sudoku hints and tips above in mind.
The fastest Sudoku winner
In 2 minutes and 8 seconds, Thomas Snyder of the United States won the 2006 quickest Sudoku competition. However, in 2008, Lucus Yeo, an 11-year-old Australian from Castle Hill (NSW), triumphed, sorting the cards in 1 minute and 38 seconds.
