Should deffinatly get a 3 star rating. Even after figuring out the 1/9 possitions the sudoku is difficult.
Very nice puzzle. well done on the setting!

I created an account to comment on this sudoku. One of my favorites I have solved. It flows very smoothly from start to finish. Amazing!

Clever construction. Definetly more than 2 stars for me.

Great puzzle! Agree that it felt like 3 stars.

I often feel that the difficulty is marked too low and it should be higher, but for this 2 stars felt just right

Well said, h5663454! This puzzle requires many bits of beautiful logic that overall make it a fair 3 stars puzzle in my opinion.

I liked the 'sun clearing through the fog' effect. Thanks!

I agree with h5663454. It might be a 3 stars puzzle. Very nice logic required and really entertaining. Thanks!

Hmm...nice idea.
In fact, even if there is no fog, its difficulty is far more than 2 stars (I personally think it can reach 3 stars), provided that you really make rigorous logical reasoning, instead of repeatedly filling in several numbers in each grid for trial and error until the correct answer is obtained.
All in all, it could have received a better rating.
