Update on the Auto-Check Feature

We have changed the specifications of the auto-check feature:

Lines that can be logically filled will now display a blue arrow (excluding temporary placements / trial-and-error).

If there are any incorrect cells in a line, the blue arrow will not appear, and a red "X" will be displayed next to that line.

Since this feature is still under development, there may be cases where no arrows appear at all. In such cases, you can click the pencil icon in the bottom-left corner to find out where you can fill in cells using the trial-and-error (temporary placement) method.

For monochrome puzzles, there will always be cells that can be filled without using trial and error. Even in color puzzles with many empty cells (as a general guideline, 20 or more), we believe there are still areas that can be solved without relying on trial and error.
