I'm interested in getting additional levels for kgoldrunner.
I'd like some intermittent as the challenging ones are to hard for me.
I thought there might be a repo or something somewhere.

Have you checked on kde-look.org to see if any user contributed KGoldRunner levels exist?

No, I never heard of it.
Wow, there's a lot of stuff there.

Ok, I,ve searched under the name kgoldrunner and goldrunner and it comes up blank.

Unfortunately that likely means there are no other levels available, outside of those shipped with KGoldRunner itself i'm afraid. I am not aware of any other places where additional levels could be found.

All the available levels are shipped with KGoldrunner.

People use the game editor to compose levels and then they send them to me for inclusion in the game. But they always seem to be Championship levels ... I could not win the last ones I received and I am the author ... There are some hints in the Handbook which might help you take on more of the existing levels. You could also edit some levels, make them a bit easier and then save them in your own game.
