About this game

OUR NEWEST PACK – CLASSIC VOLUME #2!

Classic sudoku is where it all began, and there is still lots of skill to be deployed to solve classic puzzles, and new techniques to be explored.

Nikoli, the Japanese puzzle house, named and popularised sudoku from 1984, and we have commissioned 20 puzzles from them for this Classic Sudoku 2 app. We have also created 20 ourselves, and sourced 20 more from Sam Cappleman-Lynes, the brilliant British sudoku expert. The result is a wonderful 60-puzzle pack which will delight and challenge you.

--------------------

Welcome to the brand new Sudoku app from the most popular Sudoku channel, Cracking The Cryptic.

Unlike other Sudoku apps, we feature handcrafted and curated puzzles from the world’s best Sudoku constructors. Each collection features puzzles made by various authors that are now familiar names to those who follow the channel. Authors like Phistomefel, Clover, Sam Cappleman-Lynes, Christoph Seeliger, Richard Stolk, jovi_al, Qodec, Prasanna Seshadri and of course, Simon and Mark!

Downloading Cracking the Cryptic will give you access to our first free collection – a variety pack by Prasanna Seshadri featuring 7 puzzles inspired from our previous Sudoku apps; Sandwich, Classic, Chess, Thermo, Miracle, Killer and Arrow Sudoku. We also have purchasable packs designed for all skill levels and featuring many unique variants not seen previously.

We’ll be releasing more free and paid packs in the future so keep an eye on the app for more Sudoku content from Cracking The Cryptic!

I love this game! It's made it hard for me to play other sudoku apps because the controls/UI are inferior lol. One small feature I wish it had is a toggle for the pen tool visibility. Sometimes it's hard to see highlighted numbers (from selecting that number) when they're also coloured. There's also a bug right now where the pen tool lines don't appear over fog of war. Finally, I wish you guys combined the puzzles from your other apps into this one. I want to play more killer and chess sudoku!

Love the game, but the lag in the menu is getting pretty long, once you've got a lot of puzzles completed. Also, don't know where else to leave feedback, but some puzzles aren't communicating all of the logic needed. For example, Fog #32 appears to have an anti-knight restriction (see Hint #5 needing it and it being stated explicitly in the final hint), but it's not listed in the rules. *EDIT* Has been corrected.

Menu text doesn't fit on my screen, it goes off the edge and I only see portions of the words. I have a large 6-inch diagonal screen. Only 4 stars so they perhaps can have the devs make it work better on my device. Otherwise, I think this is a decent app that allows one to pay for puzzle packages from within. I love the CTC channel and want to provide constructive feedback.
