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!

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.

Really nice challenging Sudoku you don't find elsewher. Hints are very educational. Sometimes, they do describe situations I already figured out, though. I wish it could solve hint the next step like another one of my Sudoku apps does, or at least a way to export it as a string so I can import it to an online tool. Also, I hate how it hides my bottom buttons to switch to home. This is the puzzle app I reach for when I'm bored, and will probably to continue to be. Interface is very solid, imo

This is a great app from a great team. I've enjoyed the challenging hand crafted puzzles. The only thing really preventing this from being a 5* review is the lack of a true dark mode and the amount of battery it seems to be eating up when I play (maybe those are related). Other than that, I recommend people buy this. It's worth the money. Oh yeah...I would like a layout for landscape/tablets and a way to mark completed puzzles that were tough to replay later. Those aren't impacting my review.
