All about release 18 of SudokuDragon
Comments and information about release 3.0 (18) of Sudoku Dragon.



















A major new release 3.0 (build 18) of Sudoku Dragon is now available.
It supports an extra seven sizes of puzzle grid - all the rectangular ones from 2x3 through 3x4 to 4x5 making the largest grid so far supported now 20x20. We hope this is enough of a challenge for you.
At the same time we have changed the puzzle hint interface. Now you can leave the puzzle hint open and use it to solve multiple squares. A new hint type has been added to allow you to see in the grid itself why a particular square can take a particular number.
For those experts amongst you we have added a new possibility display option. This excludes the possibilties you set (using CTRL+number keys) from those displayed as possibilities so they act as excluded possibilities - you can now mark possibilities that you know aren't possible.
Also the Undo and Redo facility has been extended to setting possibilities so that the program will now remember when you put in your possibility marks on a square.
Comments and requests for features in the next release please!
The full list of new features, enhancements and bug fixes are in the release note
