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!

Whoa, what did you do with that August 25 update? This is much worse. Numbers in the corner notation look weird and unpredictable this way, and it's no longer possible to select cells by sliding your finger off the board and on in another position, making it harder to select all the cells not seen by existing placed numbers. Please reconsider :( edit: taking off another star, it completely throws off the flow of my game, taking away my "comfort food" game on my phone. why fix what wasn't broken.

The best thing about this app is the quality of the puzzles, although I would like to see more difficult puzzles. The interface could be better, the most annoying thing in my opinion is that the numbers are lined up in a row instead of like a numberpad. Because of this the numbers are too small and it takes more effort to press them regardless of size, because pressing the right position in a numberpad is easier to do without looking closely.

Love the loaded games. But using the interface is NOT intuitive. Example: I turn on coloring the squares and fumble my way to actually coloring some of them. Hooray, right? Wrong. I swear there is absolutely no way to switch back out of coloring the squares! I've tried everything available on the interface, but no dice! WTH? And just you try to find any kind of tutorial on how to navigate this app. Hello? Instructions anyone? I really want to be able to use this thing but can't get help!
