AB SuDoKu 1,5

It's a classic (9x9) Sudoku game. Using the program, one can either play on a PC or print generated puzzles. Because the generation occurs on the fly, practically unlimited number of free sudoku puzzles is available. Also puzzles can be entered manually and the tool can be used as a sudoku solver. Enjoy!

What's new:

- Better support for mouse-based play: Toolbox allows to select a digit to put on the board. The board itself can also be used as a toolbox. Any number on the board can be picked up by right-clicking it. Left mouse click resets cursor to normal.

- New option to reduce generated puzzle complexity: This option controls how the new puzzle is generated. By default generated puzzles do not have moves where guessing is required.

- Auto-pick last number in a 9 digit sequence: When all the numbers but one are known in a row/column/quadrant, the remaining number can be automatically picked up by mouse. This eliminates necessity for obvious but routine calculations, when the last number is opened in a 9-digit series.

- Optional automatic check for new updates: This ensures easy notification for latest product updates. The check occurs once per week. The check is also available per user request.

Upgrade instructions:
It is recommended to uninstall Ab Sudoku 1.0 before installing the version 1.5. ABS files saved by previous version are valid for Ab Sudoku 1.5.

 

Version 1.0 features:

- Puzzle generation: A new puzzle is generated in two steps. First, a random valid SuDoKu board is generated with all cells open. Second, cells are randomly cleared and the program checks for the uniqueness of the resulting solution. Once the maximum number of cells is removed, the puzzle generation is complete.

- Suggest Position/Move/Solve the Puzzle: There are toolbar help buttons that will suggest a position for the next move, open the next cell or solve the puzzle.

- Puzzle Rating: The rating system is definitely something I'm planning to improve. See this topic in my blog for the current rating system.

- Code Copy/Paste: Also something I'm planning to improve. Before you paste the code, please review it in the preview dialog (see screenshot) as this operation will clear undo/redo buffer.

- Print: The program prints two identical copies of the board on one page. The plan is to make print layout customizable by user.

How to play

It's easy to learn to play. The goal is to fill in the empty cells, one number in each, so that each column, row, and region contains the numbers 1-9 exactly once.
