Here you find the version history of the MaaTec Sudoku program with the respective
changes in each version.
MaaTec Sudoku 1.93
- Enhancements and fixes for the Windows Vista and Windows 7 Game Explorer installation.
MaaTec Sudoku 1.9
- While editing Sudokus, you can now paste data from the clipboard into your
newly created puzzle.
- The creation algorithm for medium and easy difficulties was modified to
create even more 'human' solvable Sudoku puzzles.
MaaTec Sudoku 1.8
- The new detailed Hint function displays now also the numbers that are the
cause for a unique solution of a specific cell. It is of course still possible
to use the simple hints of the previous versions. The display time for the
hints can be adjusted.
- The symmetrical pattern creation algorithm was enhanced again and will
now avoid to create Sudoku patterns that contain rows, columns, or areas
two free cells.
- The program can now highlight the row and column of the standard board
that are currently under the mouse cursor.
- On Windows Vista, MaaTec Sudoku is integrated into the Game Explorer.
- The GUI was reworked and now also supports XP- and Vista-themes.
- When printing Sudokus, you can add a footer to each page that may also
contain page numbers and the chosen difficulty.
- The boards package '7x7 to 9x9 - Wood, Metal & Glass' and a new 9x9
metal board graphic were added to the setup.
MaaTec Sudoku 1.7
- It is now always possible to save an edited Sudoku, even if now solution
- The symmetrical pattern algorithm will create especially difficult and
small Sudokus with less initially visible values than before.
- Graphic Sudoku boards are now also copied as device-independent bitmaps
to the clipboard (in addition to the metafile and text format).
MaaTec Sudoku 1.6
- The visible cells of a newly created Sudoku puzzles can be arranged as
symmetrical patterns. The Settings dialog can be used to restrict the kinds
of patterns that are used for this purpose.
MaaTec Sudoku 1.5
- Fully reengineered algorithm: Easy Sudokus become even more consistent,
difficult Sudokus are now more challenging, and 'counting solutions' for
single cells may only be needed for very difficult Sudoku puzzles.
- When editing your own Sudokus, it is now possible to manually activate
the deep solver for larger Sudoku puzzles (for sizes up to 9x9 cells it is
always used). Thus it should now be possible to find a possible solution
for any Sudoku size. (The previous versions sometimes failed to find a solution
for larger puzzles.)
- Marks can now be set for Sudoku sizes up to 32x32. For larger Sudokus a
marking grid is used instead of text/number markers.
- When displaying all valid values in each cell, you can use filters to display
only specific numbers in all or individual cells.
- The settings for game control, game help, fonts, and colors can be exported
and restored. This way you can quickly change your preferred settings for
different kinds of Sudoku puzzles (e.g. use digits from 0 to 9 for 10x10
letters for 16x16 puzzles).
MaaTec Sudoku 1.4
- Small marker numbers can be set with the middle mouse button or via Ctrl
+ left click (with Sudoku sizes up to 16x16).
- New help functions, e.g. display of all valid values in each cell.
- Extensive customization options for the standard board (fonts and colors).
- Sudoku graphics can be put on the clipboard either colored or in black
- The game clock will be paused if the window is minimized.

of the current Sudoku.

- The last used board design for each Sudoku size is now saved and will be
restored any time this size is selected.
- The selected difficulty level is displayed in the status bar.
MaaTec Sudoku 1.1
- Enhanced Printing: You can print now up to 12 Sudokus per page, add continuous
numbering to the Sudokus and their corresponding solutions, and the Sudoku
difficulty is now regarded correctly.
- Unicode support for the characters that are used in the Sudokus. This
allows simpler output of numerals of foreign scripts that are not contained
in the currently used code table (e.g. Arabic-Indic or Chinese
- Slight changes to 'difficult' Sudokus: These will now have always throughout
the game at least one cell with a unique solution (as the medium and easy
Sudokus). To retain the previous behavior, the new 'very difficult' level
