Hi

I tried your script in CHROME

I put in Tab console for line 1795
d = a.J

And I obtained
176

Then I removed break point and run
A circle is running and locked perhaps at 95%
And puzzle isn’t solved
I tried with and without user

My puzzle is : https://www.jigidi.com/solve/2ssbu5jg/dauphins/

Could you help me please ?

Thanks

Didier
