Nice game but sometimes a bit vonfusing..

[donaud]

...a BIT confusing ??!! This is utterly diabolical

I keep getting so close !

well - have at least 1 mistake and need to let the dog out, and a couple of other things and head to bed. Shall try a fresh start tomorrow

I did save the gals from the ice king - yippee. Now to try this again.
Well well well - the squares not only move or rotate - some # change place. Stop chuckling .. I was tired last night.

Almost ... 3 different numbers not (as in 5, 7 & 9) not working .. I've deleted all and still can't get it to work. I also noted white numbers at start - some of them have disappeared?
Hint as to what I'm not considering?

Finally beat one (WAY off ablejack's time) !!

@ Nanna:

As far as I can tell, it gives you (effectively) a new puzzle everytime you fill in a square. You are just one square closer to solving it !

So sort of luck.. second time I played I put a different number in the center square of group thinking there was rotation ... that proved false. Hmm. May play around with it again...
30 minutes ... not getting it today.
