Break-in could almost be 4stars but after that it flows very nicely

Wow, what a great puzzle! Struggled a little bit (a lot) at the beginning to spot the breakthrough, then I realized, "this is it!" And boom, highway to end (of the puzzle). The whole solve was truly enjoyable!
Thanks a lot Allagem!

Caught the break, then slowed right down
Pleasant puzzle so far, though

Fantastic Puzzle again Allagem!!! Really enjoyed the progression of this one. My first Quadrupler puzzle solve and a memorable one at that.

You need to get idea overall whats happening. Nice one. Enjoyed a lot. Difficulty 3 star is correct

Caught on the initial idea pretty fast which made this not too difficult, but I can see how finding the break in could take time and even be a bit frustrating.
For me it was very enjoyable and quite a bit different than any quads sudoku I've ever done.

Both versions are lots of fun! I definitely had a head start on the second one since the opening was similar to the first, but you're right that it's a fair bit harder -- a bit of a sting at the tail!
