The graphical interface provides all the information you want with many options to control what you see and its display style. The menu and toolbar have a host of useful options all documented in our context sensitive help topics. They are also available from the keyboard, many as single stroke function keys.

The screen shot shows a puzzle being solved at 'beginner' level. Many of the possible Sudoku square allocations are colour coded to make solution easier. All occurrences of the number 7 have been highlighted using the possibility toolbar. Any squares that might possibly take the number 7 are indicated by a small number in the top left corner. This is one of the many optional features of Sudoku, experts may want to work this out for themselves. The highlighted square Dg is one that can be easily solved, the Row D has a '2' missing and because of the occurrence of 2s in column a,d and i this is the only square in the row that a 2 can be allocated. Two of the '7's are highlighted (this is an option) to indicate they must be allocated in the squares Da and Gb. This is beciase in both case it is the only square in the in the region that can take a 7. To make this clear, the two special possibilities for 7 are highlighted with a sky blue background.
