About this app

Developer Description

Handcrafted Sudoku puzzles by the most popular Sudoku channel!

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!

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.

The puzzles are very enjoyable and the hints keep you from grinding to a halt without giving away the entire puzzle at once. My only complaint is that the compact interface makes it very easy to click the wrong thing by accident. For instance, on the very last puzzle (#100) while attempting trying to jump from Coloring Mode to highlighting all the digits in the grid for that # I accidentally entered the number into the box which turned out to be correct. In doing so I gave away the entire solve.

500 characters isn't enough so i'll write in short form Cracking the Cryptic is awesome/ Mark and Simon are awesome/ the hand crafted and tested puzzles are awesome/ this app is not good... at all. if a bare-bones, barely functional app is your thing then you'll like this one. if you were expecting a top-notch app worthy of the name 'Cracking the Cryptic' then you'll be as disappointed as i am right now.

Content and UI are absolutely fantastic, but after a device software update it keeps crashing. This happened a few months back as well. I managed to fix the issue by reinstalling the app, but lost all progress and had to start from 0 again Edit: again, after a device UI update, the game crashes on launch. Problem is persistent and doesn't seem to get addressed by developers. Lowering my rating in hopes of getting this issue on the radar

Suddenly stopped working. The sudoku are quite challenging, the order of them and lack of access to all games i do not understand.
