Playing Version 4.0 (29 Jan 2015)

1. Run kmines by clicking start->All Applications->Games->Tactics & Strategy->kmines
2. Run again same way


Actual Results:  
Random boards

Expected Results:  
Boards very much alike

Snapshots of two such boards will be in a comment.

The best way to see difference is to display the two boards in windows one above the other and to alternate between one board and the other.

As you can see two boards are exactly identical. I was able to win in second case using previous snapshot.

I'm running Arch linux:
extra/kcoreaddons 5.21.0-1 (kf5)

Comment 8 Frederik Schwarzer 2016-05-02 12:50:31 UTC

Ok, that's the affected version. And KMines uses KRandomSequence (from KCoreAddons) to generate the mine positions.
The issue has been fixed last week and packagers have been notified to ship updates as soon as possible.
In Fedora, the package kf5-kcoreaddons-5.21.0-4 contains the fix. It should land soon.
https://bodhi.fedoraproject.org/updates/FEDORA-2016-1707f83508

Please update and then try again.

I will close this issue. If the problem remains with said package, please reopen.

Thank you for your report and sorry for the long delay. KMines does not have a maintainer at the moment.

Sorry, got confused because the initial report sais "Fedora RPM".
On Arch, the issue should be fixed with kcoreaddons 5.21.0-3 which looks to have been roled out about 5 days ago.
