There's even an undo button in the bottom right corner of the interface, that allows you to reverse that when, inevitably, you're either forced to brute force a puzzle, or, you happen to left click a number by accident.If you enjoy our free web content, consider giving a donation back to the site or to the authors (name the amount/author in your donation as appropriate if giving to a specific contributor) When you pick a big number it saves you the trouble of manually deleting the notations that are in conflict with it, by doing it automatically. As mentioned, that just seems like cheating to me. Some count it highlighting your errors there. The good news is the game isn't borderline unplayable, like Konstructors' Sudoku Killer, for example. And it gets still more interesting when those become 2 digit sums. Sure, not knowing what that number is does make it more interesting. It's just the cage sum happens to be an the adjacent number in the circle. The "arrows" are just the "cages" like those in killer sudoku. But legit', 1 and 3, 3 and 1, and 3 and 1, VERSUS 3 and 1, 1 and 3, and 1 and 3 being two different possible solutions for 6 unsolved squares.)

The software offers the same excellent choice of settings, but even the default settings are improved and more intuitive! I liked them enough I ended up going back and setting the other apps to the same settings as this one, after realizing the other apps also offered those settings, but didn't come with them turned on. If you have any interest in puzzles or especially Sudoku, don't miss out on this app. So overall this should be good for new Sudoku players and also be interesting enough to keep experienced solvers occupied and engaged as well. Details like that are where it goes above and beyond for me. There are even animated rays of light shining in the background! What more could you want? It's a puzzle app. I find that it's a theme I like and appreciate. The app itself is quite beautiful and obvious effort was put into polish and a themed environment. It's not heavy math in Killer Sudoku, for example, you need a calculator to keep track of the different options (which they provide in their Killer Sudoku app as well), but here, it's simple enough math that you don't really need it. It does involve math, which may be a good thing for some, and less enjoyable for others.
Not extremely difficult like some of the other varieties, but definitely harder than, say, Sandwich Sudoku or Thermo Sudoku. In terms of difficulty, Arrow Sudoku is about medium. This is the best Cracking the Cryptic app so far.
