Is Sudoku a hobby worth exploring? Definitely yes! And now let’s dig a burning question that stops many from playing the game — how to solve Sudoku with math?

## Sudoku and math

You may have heard that the Sudoku game online doesn’t require math skills. But what it actually means is that there is a mathematical way to solve Sudoku but arithmetic is not required. Free easy Sudoku puzzles online use digits from 1 to 9, where some are milling. Players are using logical deduction which, in fact, is mathematical thinking which is useful for solving Sudoku with math.

### How to solve Sudoku using math?

There are 2 strategies to solve Sudoku with math, so let’s explore what they entail!

• Forced Entry — #1 mathematical solution to Sudoku. The widely-known basic strategy of solving Sudoku puzzles. You need to first write down all possible entries in each empty cell. Each entry should not contradict the One Rule. When a certain cell has only one possible suitable number, it is called a ‘forced’ entry.
• Digit by digit — #2 mathematical solution for Sudoku. Another strategy is to start with picking a digit and a row/column/block. Note that the One Rule can’t also be violated. If you find a spot where the number can only be put once in the neighborhood, you should place it there. After that, the chosen digit can be eliminated from the connected neighboring row, column, or block.

Following these two strategies are usually enough to successfully solve any Sudoku puzzle of basic levels. But for some medium level and all hard level Sudokus players need more advanced analytical math methods like:

1. Guess-Proceed. If you don’t have a forced entry cell, but a few suitable numbers, you can pick one and proceed with it to make progress. If the situation results in conflict, you need to backtrack.
2. Triple cell. Another more complicated strategy is where you scan pairs or triples of cells within a row/column/block (your choice). You might find a pair of cells with 2 possible entries. This strategy doesn’t give you an exact number to put in, but it provides information that both digits cannot be anywhere else in the neighborhood. Similarly, triple cells eliminate 3 entries. Now you know how to solve Sudoku with math and can enjoy the best free online Sudoku games from the comfort of your phone with SudokuPro.
