Sudoku Puzzles
Sudoku is a logic-based, combinatorial number-placement puzzle. The objective is to fill a grid with digits so that each column, each row, and each of the sub-grids contains all of the digits exactly once. Click here for instructions on how to solve a Sudoku puzzle.
How to solve a Sudoku
The aim of Sudoku is to place a number from 1 to 9 (or whatever the dimensions are) in each blank field.
Click on a cell and choose a number to fill in the cell. You can click on a filled cell and choose the trash symbol to delete the cell.
Each columns, each rows and each outlined region must contain the numerals from 1 through 9 (or whatever the dimensions are) exactly once.
Check existing numbers to fill in blank fields. In this example we look at the 3x3 region on the right.
The number 3 is already contained in the upper and the middle row. Therefore, the marked cell would be the only one that would contain 3. In the second example, 7 goes into the marked cell similarly.
Sometimes a puzzle can be completed by searching the missing number. Of course there are many more tips to discover as you go along solving Sudoku puzzles.
