About this game

Presented by Cracking The Cryptic, the most popular Sudoku channel, this is the brand new “Classic Sudoku” game that their viewers have been requesting for the last two years!

Simon Anthony and Mark Goodliffe, the hosts of Cracking The Cryptic, have assembled a most extraordinary collection of sudoku puzzles. The sudokus in the game cover a wide range of difficulty with something for everyone - and also require an incredible range of techniques to solve them efficiently! Each of these special puzzles had to qualify for inclusion in the game by passing our rigorous play-testing - a test that NO other sudoku game on the market would pass. This play-testing ensures that a human being has actually thought about the journey you, the solver, will go on as you work through the puzzle. No computer testing here!

Indeed our more advanced puzzles have been carefully designed to showcase some of the diabolical techniques in an intuitive way with the aim of helping solvers UNDERSTAND the patterns involved.

In Cracking The Cryptic’s games, players start with zero stars and earn stars by solving puzzles. The more puzzles you solve, the more stars you earn and the more puzzles you get to play. Only the most dedicated (and cleverest) sudoku players will finish all the puzzles!

Featured authors include (obviously) Simon and Mark but also some other authors who have produced popular puzzles on the channel!

Mark and Simon have both represented the UK many times in the World Sudoku Championship and you can find more of their puzzles (and lots of others) on the internet’s biggest sudoku channel, Cracking The Cryptic.

Features:
40 beautiful puzzles on launch
5 new levels every month for the first year (a total of 100 levels!)
Hints written by Mark and Simon!
Handcrafted Sudoku puzzles by the most popular Sudoku channel!

Lovely app, beautiful puzzles, by far the best sudoku app in existence. Handcrafted puzzles made with thought and care about the users experience. An absolute delight to use. Absolutely worth the money, much cheaper than a sudoku book and it comes with the convenience of being on your phone. Would love to be able to make corner and central notation amd maybe an option for larger number buttons as it can be a little bit fiddly when trying to input a note and accidentally pressing the wrong number

Almost the perfect sudoku app! I've knocked off two stars for the following: 1) There's no option to add an external puzzle. The controls are fantastic, some of the best out there & it's a shame you can't manually add (or even better, use the camera to add) a puzzle from somewhere else. Please add this feature for another star! 2) No support for dark mode or a dark option. Playing at night or in low light is a bit harsh on the eyes, so please can you add a dark/night colour option. Thanks!

The ONLY sodoku app I have found that allows both corner notes and center notes. For that reason alone, it is the best Sudoku app on this platform. Because of that, I am begging the creators to allow us to enter puzzles from other apps. An amazing function would be to be able to take a picture of a puzzle and have it entered into their platform. But at the very least they should allow us to enter other puzzles onto their platform and work them. Thank you all so much for such an amazing app.
