Nice pattern! Only 2 solutions for the last 3 dots in each corner - no problem when you use temporary mode. Thanks for the fun!

Symmetrical, and the last few dots are easily picked when you go off what's already been placed. Simple and not too difficult at all. Nice pattern.

Very logical when you follow the pattern for the last dots. got it 1st time. thanks.

Thanks.
