★☆☆☆☆

I've been playing one "Nightmare" mode game for multiple years. I've restarted the same game multiple times. I'm very well versed at various forms of Sudoku. I am confident in saying at this point that the puzzle this app generated is impossible. Not just very difficult. No, it's literally not possible to solve. Don't use this app if you want puzzles that can be solved.

It just works. The only time I got mad at it was when I hit the hint button on accident, but there's a menu option to turn them off. I suspect that one of the puzzles on the diabolical difficulty is actually impossible, but either it is impossible and the developer put it in there to mess with us, or it is possible and I'll have to get better to figure it out. Either way I like it.

★★☆☆☆

I previewed numerous Sudoku games, and liked this the best. After 150+ games, I'm not disappointed. I went ad-free, though the ads weren't obtrusive - worth it. I do wish it had a teaching component for advanced strategies such as X-wing or Swordfish. Taking off 3 stars as there are far, far too many repeat games, even though it touts an infinite puzzle generator.

I have tried a few Sudoku grids, but this one is the best, so far. What I love most, is the grids and the numbers, are big, as well as it goes dark mode. This makes it easier on the eyes, as I do not have to strain to see the 'notes', nor squint against the glare of the page. Thank you for an awesome experience...this morning, alone, I have cracked the 'Diabolical' 4 times, in under 15 minutes, each time.
