Sudoku Susser is a free program that helps solve Sudoku puzzles.
In addition to being more convenient than pencil-and-paper, the Susser also can show hints, solve the problem step-by-step using human deductive reasoning, or brute-force solve it using recursion.
You can drag Sudoku problems directly from web pages, save, edit, print and more.
And if you like the program, you can tip the author to encourage him to improve it.
Main features:
- You can drag Sudoku graphics from the webpages of major UK newspapers and theyll be scanned and loaded into the application.
- You can manage, rename, reorder, and print out your Sudokus.
- Undo and redo are fully supported.
Enhancements:
- Added ability to unlock a stash of puzzles from my Sudoku books (Brainiac Sudoku / Sudoku To Go) if you know the ISBNs. Coming soon to discriminating bookstores!
- Naked Set / Consequence Tree buttons "stick" to their shifted/unshifted state when selected, so they show you which version of the hilighter is active.
- Reclicking on a selected hilighter now turns it off.
- Reclicking on a selected row/column label now toggles the hilighting. Note: if you shift-click a label, then clicking sets the hilighting to the regular hilighting; you have to click in the same way as the current hilighting to take it down completely.
- Added "ESC" button (with eraser icon) that disables current hilighting (it was about the only thing you couldnt do with the mouse!)
- New "Possibility Numbers (when hilighted)" color option in preferences lets you use a different color for the possibility digits when the square is hilighted. Many people prefer white to the default green in this instance.
- Susser now recognizes files of type ".fetch" to be the same as ".url" url list files (.url has a special meaning under Windows)
- Changeable colors can no longer have 0 saturation, as this was apparently causing some problems on some Linux implementations.
- Initial squares are now lightly shaded on printouts and graphic puzzle drags (unless your printer is totally lame...)
- Fixed crashing bug when you used the comprehensive consequence tree hilighter (shift-t) and hilighted a pinned square.
- Use Line Connectors, Concise Defuction Output and File -> Half Sized Puzzles preferences were not being saved/restored properly.
- If you solved the puzzle incorrectly when in Marquis de Sade Masochism Mode, the Susser would congratulate you! Thats sadistic, not masochistic...
- Graphic puzzle OCR was claiming that hints were being turned off after load, but this was no longer true; message removed.
- Set Initial Squares now properly updates the "changed" state of the puzzle, and also resets the Undo stack (since this operation cannot be properly undone at present).

Sudoku (pronounced soo-dough-coo with the emphasis on the first syllable) is a simple number-based puzzle/game played on a 9x9 grid that is divided into 3x3 subgrids. The goal is to enter a number from 1 to 9 in each cell so that each number appears only once in each column and row. In addition, each 3x3 subgrid may only contain one of each number.

How to Play the Game

At the start of a new game, Sudoku fills in a random selection of cells for you - the number of cells depends on the difficulty level you use. Click in any of the empty cells or use the arrow keys to highlight individual cells and press a number from 1 to 9 to fill in the cell. To clear a cell, press 0, Delete, or Backspace. When you have successfully completed all subgrids, the entire puzzle is highlighted until you start a new game.
As you work to complete the puzzle, you can display possible solutions inside each cell by holding the Shift key and pressing each number in turn. Repeat the process to remove individual numbers, or press a number without the Shift key to replace them with the actual number to use.
