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!

Newly ascertained bug: If you place a digit, all corner and center marks should be cleared in that digit AND "seen" same digit marks should clear; that doesn't always happen in fog. (OLD...) The real not-saved issue is caused by performance of cloud data, the workaround is to not close the app, not even by "back" button. if you switch directly to another app or press the desktop button it will eventually save.

The 33 free puzzles were fun, if a bit easy. The paid packs are too expensive for what you get. I would rather make a larger (like $10-20) one-time purchase to unlock all puzzles, past and future. The small purchases of a few puzzles at a time smells too much like microtransactions for my taste.

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.
