Sudoker helps you play and solve Sudokus with accelerated workflow. It aims to combine the functionalities of a solver, generator, and sudoker player, along with many other side functions. It is still in its primitive stages and will have new functions and features added.

Note: it’s not being updated regularly, and needs a huge update for the Generator functions.

To do list:

• Unique hash for each sodoku, but same for sudokers that are equivalent by symmetry
• Sudoku database support
• a Working generator that can generate/fetch desired sudoku in reasonable amount of time
• more solving techniques and thus better accuracy when rating a sudoku’s difficulty
• AI support to import sodoku from images / camera
• support for other platforms/operating systems
• proper documentation, JavaDoc
• it’s own webpage

Features

Main features:

• Instantly solves any sudoku
• Find up to 100,000 solutions of a sudoku
• Solve a sudoku step by step according to different solving techniques (so far there is only a few implemented)
• 3 sudoku view/edit modes: show all candidates used in solver, show pencil marks made by the user, or blank for unsolved cells
• Press the tab key to traverse to the next cell of a sudoku board
• Sudokus can be exported to text or file and later imported back
• Generate sudokus with clue number and location settings (later will have difficulty and other options too)
• Convenient highlight options
• Check a sudoku’s validity (i.e. conflicts and number of solutions)

Sudoker values user preferences, and supports preferences including the following:

• Custom location for the folder to store application files
• Custom application global font size
• Different look and feels and metal themes support
• Custom sudoku board visuals
• Custom digits to display instead of 1-9
• Custom keyboard shortcuts
• Custom default order for solving techniques in step by step solving
• Setting for maximum number of solutions to look for for a sudoku puzzle, up to 100,000
• Different colors and settings for History Trees
• Option to automatically save opened sudokus when exiting, and reopen them the next time the application is opened

Other Features:

• History Tree shows non-linear history of changes made to a sudoku board
• Board Comparator compares the differences between 2 boards
• Has a music player that mostly plays .WAV files, and is not memory or CPU efficient.
• Very basic print support for a sudoku board
• Each sudoku board comes with a stopwatch
• A Memory Monitor Panel that supposedly monitors application memory usage.
• Provides a metal theme to resemble “dark mode”
