Classic Sudoku!

Simon and Mark have done it again, and this time have brought even more to the party than with their sandwich sudoku app (which still receives excellent updates each and every month as promised). The dual notes capability (which can be turned on in the options) gives a comprehensive capability to pencil marks and notation that far surpass any other app. Each of the 5 early puzzles I've completed have all felt unique and challenging, without being absolute gimmes. The guest puzzles from the master of Thomas Snyder are beautifully designed and very enjoyable to solve as well. Unlike other sudoku apps that generate random puzzles with an algorithm, these puzzles are clearly handcrafted with care, each giving a certain amount of designed logic that cannot be found with computer made sudoku. For those who love handcrafted puzzles from Nikoli or GMPuzzles, this is the app for you. While no advanced logic has been required as of yet, I fully expect the difficulty to ramp up significantly as they have done in the sandwich app, and I can't wait to see those puzzles!

Updated review: I have completed level 26 with 98 stars and I'm even more impressed with this app. The puzzles are all beautifully designed and some are absolutely exquisite. I am learning so much and can see that these will have replay value. I do have one request: I have fat fingers and sometimes accidentally touch a known value next to the cell I intended to choose. It would be great if known cells could be locked once the values has been inserted. Kudos to the team who created this app! Initial review: I’ve been watching Simon’s videos for about a month and was so excited to hear this app was coming. I still have to remember to use the back arrow when I’ve made a mistake so I don’t erase my previous pencil marks, but other than that this app is all I hoped for and more. I’ve completed only five of the puzzles so far and I already feel I’ve learned so much. Thank you for this fun and challenging game and learning tool!

I really like the app. I am about halfway through and there are certain puzzles that I have had to skip and keep coming back to (such as 4 and 11) because I haven’t figured them out yet. The notations are simple to put it and work well. The only feature I miss from my previous sudoku app is that when I’ve filled in all the number ones, the round button for #1 could show that to me by e.g. fading a bit. That way it’d be easier to keep track which numbers remain.

I’ve just recently gotten into sudoku, and have been playing around with a few others from the App Store. This app is entirely worth the $5 for it. It’s intuitive, easy to navigate, is entirely customizable, and the best part: from what I know each of these puzzles is handmade with huge amounts of attention to detail, unlike the other apps that seem to generate them randomly? Idk it’s what the other guy said. I’ve legitimately only played the first puzzle and I’m in love

The app is great!! The double notation pencil marking feature makes solving so much more efficient!! I have one other sudoku app I use, which has a manual puzzle entry feature, but it does not have the double notation pencil marking feature. If the Classic Sudoku app by Cracking the Cryptic added a manual puzzle entry feature to allow the user to also solve newspaper, magazine, book puzzles, etc using their app, then it would be the only sudoku app a user would ever need.
