Upon accessing the settings, on the right side, you will see an icon displaying two squares. This tool lets you track the number of fields you've solved in a single drag. For instance, if you are required to solve ten fields in a row, the numbers on the side will appear when you click on the first field, starting from one. As you move the finger, the subsequent numbers will be shown. Conversely, the numbers will not be visible on the side if you deactivate this option.
