Is there here somebody who likes kmahjongg?

I like it, but some are quite easy and some are very hard. I want to explore which is hard and which is easy. Fortunately for all of the games there is a unique number so one can get back there. I mean it is unique for the given layout (default, dragon…). At Game > New Numbered Game... you can open whichever you want.

Here is a table with the results so far. I would be happy to create a database if you join. There is also a number about what I felt how hard it was to solve: 1 very easy, 5 very hard
