Sudoku game info

The goal of sudoku is to fill each square in the grid with a number between 1 and 9. Each row, column, and 3x3 subgrid should contain each number just once.

Levels of difficulty

You can choose between 3 levels of difficulty: beginner, intermediate and advanced. The amount of given numbers at the start decreases when you pick a higher level, so it becomes harder to fill in the puzzle.

Tips to solve a Sudoku

Besides the general advice to use your logical thinking to solve the sudoku, there are some tips that can help you:

Strategies

There exist various strategies for filling in numbers and removing candidates. We list two of them below, but there are many more which you can discover while playing!

Sole candidate

Sudoku sole candidate

You can fill in a number if there is only one candidate. For example, only number 9 can be placed in the green box because all other numbers are already placed in a column, row or box of the green box.

Box and Column/Row interaction

Sudoku box and column/row interaction

You can remove candidates by using the knowledge that each number appears only once in a row, column or 3x3 block. For Example, there has to be a 9 in one of the green boxes. This means that a 9 cannot be placed in any of the boxes marked with an X.
