Puzzle Format - GUI
The GUI displays cell values and candidates using numbers (1-25).
Candidate input via keyboard is through keys 1-9 (numbers 1-9) or keys A-Y/a-y (numbers 1-25).
For large sudokus (bigger than 16x16), the GUI is cramped but usable!
For the larger sudokus, GUI output format can be selected from the Options menu.
For the larger sudokus, GUI input format is auto-detected.
Puzzle Format - serate, hints
For sudokus up to 9x9, numbers 1-9, one sudoku per line.
For larger sudokus, letters A-Y (for numbers 1-25), one sudoku per line.
Use the GUI to convert between formats.
Custom extra regions - layout
For sudokus up to 9x9, numbers 1-9. Or use letters A-I.
For larger sudokus, letters A-Y (for numbers 1-25).
For examples, see: http://forum.enjoysudoku.com/various-nxn-n-9-jigsaw-sudokus-t38697.html
Custom extra regions - command line
In GUI, setup the sudoku with the correct extra regions layout. Exit GUI. This saves the layout in json file.
Source Code:
The java source for SE9x9 is in this GitHub repository.
This is the reference code used by my scripts to generate and build the other SEs.
Other Notes:
GUIs should all be working, some are untested (not used! or rarely used!).
GUIs looks OK on 1920x1080 screen, other resolutions are untested.
Command lines should also work, very hard large sudokus will take a long time to rate.
The Generate code is the original SE code, may not work well for some sudoku sizes.
SE Font:
SE settings are stored in a .json file, there is (usually) not need to change these!!
The SE font used in the main GUI can be changed by modifying the FontName setting in the .json file, e.g.
"FontName":"Ink Free",
If SE settings are messed up (SE does not start!), close SE, delete .json file, restart SE to recreate .json file.
