Operating instructions for the online Sudoku ↥
By clicking in an empty Sudoku field, 9 small numbers appear.
These small numbers can be shown and hidden individually by a simple mouse click, so you can easily remember which numbers you have already excluded and which not. There are also 2 colors available for marking, whether you use both or not is up to you.
Double-click on a small number to enter it in the field. Clicking on an entered number takes you back to the small numbers.
After pressing the “Check” button, incorrectly entered numbers are displayed in red. Here, too, you can return to the help numbers by clicking on them.
Sudoku Online - Smartphone / Tablet ↥
On the smartphone or tablet, the auxiliary numbers are too small to switch them over, and in some cases it is not possible to double-click to enter the correct number. So there are additional buttons in “touchscreen” mode to operate the auxiliary numbers.
The additional buttons below the Sudoku field can be used to switch between the auxiliary numbers and also to enter a solution number. Click on a field to select it and then toggle the help numbers or enter the solution.
Sudoku online tools ↥
The “Scan everything” button scans the Sudoku for further solutions and displays them; solutions found can be entered by simply clicking on the corresponding field. If incorrect numbers have already been entered, the solutions found may of course also be incorrect.
The “Uncover” button is used to enter a correct number in a field. If a field is already selected in touchscreen mode, this will be used, otherwise you have to select a field after activating the button.
Sudoku Online in high contrast mode ↥
In addition to light and dark design, we also offer both in high contrast mode, i.e. pure black and white display. In this way, all forms of color blindness can be intercepted. Predefined numbers then have a continuous underline and incorrectly entered numbers have a dotted underline.
