The last available version of SukakuExplainer seems to have some problems generating in the fiendish range when diagonals are involved.
Interested to know if the private version 2021.6.17 of 1to9only can produce more of them.

There are a few problems (amongst, a NullPointerException sometimes!) which I encounter every now and then.
I tend to ignore these, kill the Java VM from the Task Manager if needed, and restart the GUI.urhegyi wrote:It's hard to generate ratings around SE 2.8/2.9.
Fiendish puzzles are in 2.6-6.0 range, I would expect some puzzles at the lower end to be generated every now and then.
