jigsaw pattern producing a lot of fish

Postby urhegyi » Mon Jan 25, 2021 1:26 pm

Today I saw a nice layout and when generating a batch of 305 I found more fish examples as usual. Why is this layout more convenient while other layouts seems to produce fish examples very rarely?

Is there a command line option in Jigsawexplainer to start the generator with this layout as input so I could let it run for a long time to find more of them?
Compare with a sample of 305 with another layout:
