***** SEPTEMBER UPDATE ***** 5 new levels and a new theme! ------------------------------------- Presented by Cracking The Cryptic, YouTube's most popular Sudoku channel, here is the brand new "Sandwich Sudoku" game that has become an internet sensation! In Sandwich Sudoku, the puzzle is presented with extra numbers outside the grid next to each row and column. These numbers indicate the SUM of cells sandwiched between the 1 and the 9 in that row/column. The logic required to solve the puzzles will appeal to anyone who enjoys normal sudoku and a bit of basic maths. Each puzzle here has been lovingly hand-crafted by Mark Goodliffe and Simon Anthony, the hosts of Cracking The Cryptic. They've even included their own hints on each puzzle to help if you get stuck. Mark and Simon have both represented the UK many times in the World Sudoku Championship. “I love it!” Alex Bellos, author of Alex's Adventures in Numberland Features: 40 hand-crafted levels 5 new levels every month for the first year (a total of 100 levels!) Many themes to choose from Hints written by Mark and Simon!



  • Great puzzles, powerful and flexible but quirky UI

    I was not immediately sure that it would be worth paying for a fairly small number of handcrafted puzzles, compared to the seemingly infinite variety of other (free or ad-supported) apps I have used. I am extremely glad that I took the chance. The initial 40 puzzles are fantastic. The difficulty scales nicely, and over time I learned new techniques for solving which became necessary. Puzzle 36 may be one of my favorite sudokus of all time. Initially some of the features of the UI were a bit of a mystery to me, until I watched some of the puzzle designers’ videos on YouTube (search Cracking the Cryptic). The UI closely reflects the solving styles of the designers and the tools they have developed for solving. In their solving style, notes occupying the nine number pad positions are candidates which _could_ be in a given square (I was familiar with this style). Notes closely spaced together and centered horizontally represent the _complete_ list of candidates for a given square. Numbers can be entered into multiple cells at once using multiple selection, which can be done by dragging or by using the multiple selection tool to select discontiguous squares. The tools have a lot of modality, having slightly different effects depending upon the context of the current selection(s). By the last puzzle I was extremely proficient with the UI but there was a bit of a learning curve to use it effectively. I am well aware that creating an in-app tutorial would be a lot of programming work, but I think creating a video tutorial for the UI would be well within the wheelhouse of the cryptic crew and the app could link to it to be helpful for future users. I am now a convert to handcrafted sudoku, I hope the promised new monthly content materializes!
  • Very enjoyable variation of sudoku

    By Songs72K
    I often find standard sudoku puzzles a little frustrating, but this variant of the game gives me more clues to work with, and that seems to help. I’ve played 32 of the games so far. I like the user interface, although I might want to make a few suggestions after I’ve had more experience playing the game.
  • refreshing spin on sudoku

    By Tygar37
    i just spent hours playing this game, loving it the whole time. its nice to see a refreshing change to such a classic. the puzzles are well designed... clearly handcrafted. well done to the creators. anyone complaining about the ui should take a chill pill. its better designed than most (if not all) sudoku apps out there. now give me more hand crafted puzzles already.
  • I’ve never like sudoku...until now

    By Erajan007300
    ** I know one of the developers** I’ve never cared about sudoku, despite liking games. Knowing one of the developers was enough for me to try. If you like sudoku, hard to imagine not liking this app. UI is clean and bug free. The ‘tools’ set this apart from other “brain games” I play. They’re intuitive and functional, even for a beginner. Without the tools, I would play this for 30 sec on someone else’s phone, and never touch it again. With the tools, I’ll pay $5 in a heartbeat, and play it on my daily commute. If you’re a sudoku fan, you will not regret buying this app.
  • A Wonderful Challenge

    By Grichnoch
    This is the most fun I've had with a Sudoku app. It's well designed and each puzzle presents a really nice challenge. Cracking the Cryptic and their dev have really done a great job with this app. The interface was a bit confusing at first but after the first couple of puzzles I've grown very accustomed to it.
  • 1.02 Fixed it!

    Bigger font for notes and saving progress even when you make an unorderly exit are huge! I Really enjoy the challenge of this game.
  • Love it......

    By jeff grizzel
    Give the interface a little time and you’ll love it. Seemed clumsy at first but after a few puzzles it grows on you. I really hope there’s an update that allows horizontal play on my iPad. Thanks to everyone involved for a great app.
  • Awesome!

    By davina91
    Love this app! I’m not an advanced sudoku player, but I’m really enjoying this variation. The tools are great and enhance the puzzles. And although I haven’t needed a hint so far, I’m glad they are available as I’m sure I’ll need some later in the game. Cracking the Cryptic and Studio Goya have created a smooth, polished game. Looking forward to more variations in the future!
  • Wish this app included "traditional" Sudoku

    By Universal Language
    I like the new take on Sudoku, but also wish the app had a traditional mode as well with all these great note taking tools @ our disposal!
  • Awesome!!

    I love the channel and I love this app. Just one issue, I start playing, go to work, come back to play during break and it starts you over. If the game ever times out or refreshes, it starts you over. I’ve had to start over 3 times now 🙁 Other than that, the tools are great! I’m learning different ways to use the tools as I go. Thank you!
