kmahjongg, some easy some hard

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 number so one can get back there.

Here is a table with the results so far. I would be happy to create a database if you join. Maybe the last columns should be a number: 1 very easy, 5 very hard
