Version: 0.5 (using KDE 4.4.0) Compiler: gcc OS Linux (x86_64) release 2.6.31.12-174.2.22.fc12.x86_64 OS: Linux Installed from: Fedora RPMs I used Sudoku Standard (9x9) on various difficulty levels and played it for the last months on the highest difficulty level. A few days ago (maybe 3 or 4) it started to fill in about 50% of the numbers most of the time. The position of the slider for "difficulty" had no influence on the created game. When I read the bug report 172928 I tried to find out if my game is also on "random difficulty" (I never actively change the settings until now). I just now tried to put the settings to "default" and it seems that the problem resolved. The question remains how it got into a random setting and how to control this.
I started the game again at a later time and now there is again the difficulty not influenced by the slider and the possibility in "settings" to 'SET DEFAULTS" is grayed out. So, I have no way to set the difficulty. One more comment: I used the popup-offer from the OS (fedora12) for updates regularly and allowed all updates. The last happened about at the time the problems with ksudoku started.
I frequently play ksudoku and didn't notice this problem until the first time I launched the game after 'yum update' upgraded my FC11 system to KDE 4.4.0.
I have the same problem in Fedora 12 after the update to KDE 4.4
I have the same problem for KDE 4.4.0 and 4.4.1 on Windows (MSVC-32bit, windows XP x64 edition)

I have replaced the puzzle generator and solver in KSudoku with a completely new generator and solver based on published algorithms. It will be released in KDE SC 4.8, due out in late January 2012. The new algorithms provide a full range of difficulties, from Very Easy to Diabolical and beyond, which have been tested against ratings of puzzles published in newspapers and on the Internet. Enjoy!
