SudokuGenerator is a JavaFX application whose main purpose
is, as its name suggests, to generate sudoku puzzles.
Features
-
You can generate puzzles with the following
grid sizes:
-
4 × 4 cells
-
9 × 9 cells
-
16 × 16 cells
-
25 × 25 cells
-
You can generate a puzzle either by specifying the number of cells that should
initially contain symbols or by supplying a template of such cells.
-
The application has an editor for creating and modifying a template that can be used
to generate a puzzle. Templates may be created with several kinds of rotational and
reflectional symmetry.
-
After you've generated a puzzle, you can start to solve it in the puzzle editor,
where you can use the keyboard or mouse to edit grid entries. The editor has an undo/redo
facility.
-
You can enter a puzzle from an external source in the editor. You can enter a puzzle
by typing its entries into an empty grid or by pasting text in a simple format.
-
You can save a puzzle to a file and load it later. You can open a puzzle file with a
command or by drag-and-drop.
-
Multiple puzzles may be open simultaneously in the application, and you can switch
easily between them.
-
There is a command to duplicate the current puzzle so that, after you've
generated or loaded a puzzle, you can solve a copy of it in the editor without
modifying the original.
-
When you're solving a puzzle, the application can check whether the current
entries will yield a unique solution. It can also assist you by finding the correct
entry for an empty cell that you've selected.
-
The application can solve a well-posed puzzle and display the
solution. It can find and display multiple solutions for a valid puzzle that is not well-posed.
-
You can transform a puzzle by flipping it horizontally or vertically, or by rotating
it by 90° or 180° (a quarter-turn or a half-turn). A well-posed puzzle will
remain well-posed after such a transformation.
-
You can copy a textual representation of the current puzzle or an image of the puzzle
to the system clipboard.
-
You can export one or more puzzles to an HTML document. If you export multiple
puzzles, they will be arranged in a table with a selectable number of columns.
-
There is a modeless directory-browser window in which you can display an overview of
the puzzles and/or templates in a chosen directory in tabular form. You can select
multiple files in the browser and open them in the main window or export them to an
HTML document.
