Sudoku is a type of puzzle game that has been famous globally since 2005. Solving this puzzle game requires a combination of trial and error and logic. Mathematics is incorporated behind the scenes as you play this game.

When it comes to solving these puzzles, the game involves counting grids and computational problems related to solving the puzzle. You need to understand a few things before you play your __Sudoku free__ puzzle game to help you solve the puzzles successfully. Below is an overview of the math involved in Sudoku.

**The Best Strategy to Help You Solve the Puzzle**

When gamers hear that solving Sudoku does not require any math, arithmetic is not required. Solving the puzzle is not dependent on the fact that the placeholders used are numbers 1 to 9.

The puzzle can be created and solved by any nine symbols. However, while solving Sudoku, mathematical reasoning is instrumental when combined with logic.

The most straightforward strategy to help you solve Sudoku quickly is writing the entries in each empty section. Ensure that you avoid the contradiction of the one rule in regards to the cells. If you discover that a cell has only one entry, you must fill it since it’s a forced entry.

Another strategy you can use is to pick a number and a column, row, or block, filling all the columns and rows with the number without breaking the one rule. Fill a cell if you find out that it can only accommodate that specific area. You can eliminate the chosen number from appearing in another cell after selecting the number.

When filling in a Sudoku puzzle, more is required apart from the two strategies above. To succeed in this game, you need to carry out a complicated analysis and backtracking the results.

Another complex strategy involves looking at triples or pairs of cells in a column, row, or block. Once you do this, you will realize that there are only two entries left within a couple of cells, and locating them to their rightful places will be a bit of a challenge. Eliminate the entries left in all the cells.

Try picking a box with the lowest numbers if there are no forced entries and select either. Use these strategies to help you manoeuvre through the game. Undo whatever you’ve done in case you discover any mistakes along the way.

**The Algorithm**

The backtracking algorithm is one of the algorithms used to solve Sudoku puzzles. You backtrack after fixing empty spots with numbers until you consume all of them, and then you eventually fill previous slots with various numbers.

You should first use the more straightforward approach to solve Sudoku, which involves using values in the columns and boxes to determine which numbers belong to which square. After doing that, create a list of all the values so that you can easily refer to them during backtracking.

Next, you need to backtrack the placement of items in their rightful places. You can choose to mark the unused spaces to include those spaces in the backtracking. From there, recapitulate through the unsolved sections, then place the first value where it belongs.

If you discover that it conflicts with a number from a previous slot, move to the next section after moving to the second item in the list you had previously made. The process is a continuous one, and it continues till the backtracking algorithm starts operating.

The code moves back to the last section as the backtracking continues and then moves to the next value after being filled and eventually moves forwards. The backtracking algorithm changes its direction to the backside if there is any number at the spot. Finally, the puzzle is solved once correct values are filled in the puzzle.

**Use Logical Hints Instead of Guessing Method**

While playing the Sudoku puzzle game, it is best to solve the puzzle systematically. To be able to get satisfactory results, it is better to avoid guessing and instead think logically. Guessing will often mislead you. You might discover you’ve made a mistake halfway through the game.

You are usually left with two similar numbers in a column, region, or row. Sudoku rules are broken, leaving you with a puzzle that you cannot solve. Learn to solve Sudoku through logic and reason and avoid guessing.

**Hints to Help Beginners Play Sudoku.**

First, check if there is an unsolved cell in many columns, rows, or regions. Try to solve it if you find one quickly. Find each number as you count from 1 to 9 in that column or row. The missing number should fill the empty cell.

**Where to Start**

Instead of starting from a random spot, it is better to solve Sudoku systematically. You could look for a number that contains more givens.

**Use the Scanning Method**

You can logically use the scanning method since you are now aware that every column or row can only accommodate one type of number at a time. While playing Sudoku, it is good to learn the technique since it requires you to use it.

If you manage to solve it, go over numbers 1 to 9 with the help of the scanning method and solve for each digit.

**What is required to solve a Sudoku?**

You can get all the tips and tricks you want on Sudoku, but you need to accept that more is required to become a Sudoku master. To solve a Sudoku puzzle, you need to be very strategic.

The best gamers know how to maneuver through the visual phases of the grids since they know how to study the clues. Additionally, some players can cut out any thoughts and entirely focus on the game for long periods till they solve the puzzle.

**What the Hidden Pair Means in a Sudoku Puzzle**

When it comes to this game, a hidden pair refers to numerical values that appear specifically in two squares in a column, row, or block, even though those aren’t the only existing numbers in these squares.
