Selection Cross

A single cell can be marked with the selection cross. By clicking on a cell that has not yet been revealed, the selection cross is displayed. Clicking on the same cell again will hide it again.

For some Sudoku variants such as Jigsaw or Chaos, the box in which the marked cell is located will also be highlighted in color with one click.

By marking it with the selection cross, the selected cell becomes the active cell. This will apply all inputs to that cell.

Clicking on a highlighted number again will reset this state. If no cell is marked by the selection cross, you can also highlight numbers using the buttons below the playing field.

Notes

Any cell that does not yet have a solution and is hidden can have a note added to it in the form of a possible solution. When a cell is solved, the notes for that cell and all cells related to it (by boxes, rows or columns) are removed. Notes are displayed as small values in the cell.

If a cell is highlighted and note mode is activated, the possible solutions for this cell that have already been noted are highlighted in the buttons.

Entering the solution

One Sudoku offers you three different ways to enter a solution on the board. This allows you to choose the variant that best suits your playing style.

Buttons

The input buttons are located at the bottom of the playing field. These are controlled with the selection cross. If a cell is marked by the selection cross, you can use the button to enter a solution (filled button) or to make a note (button with a circle). If no cell is marked by the selection cross, a number can be highlighted by clicking on the button.

Zen Mode

The top section of the game screen shows your current points and the time that has already passed. However, Sudoku can also be a relaxing experience where a time display is rather undesirable. Activate Zen Mode to fully concentrate on solving the Sudoku and hide the time and score display.

Playing field size

You can use the playing field size settings to set a zoom factor. This is helpful if you want to make better use of your device's screen. On mobile phones, the maximum zoom level is often already reached at the 1:1 setting. However, on larger screens the playing field can be zoomed up to twice the size.

Combo points

When you completely solve a box, column or row, your combo factor increases. If your next solved cell doesn't complete a box, row or column, it's lost again. Therefore, make sure to enter the final cells at the end of the game to earn extra points.
