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!

Bought all apps from cracking the cryptic and its evident, that they take great care in puzzle selection and difficulty curve. i love them all. this one has a missing rule in #7 though. For anyone else stuck looking at box 9 for an hour: The same custom rule for arrows from an earlier puzzle is present here, arrows sum to a single digit total. That rule was specifically mentioned before but is missing here. The puzzle has the "custom" tag but no custom ruleset, so i guess it's an oversight.

Love the puzzles and the way the interface works, and really hope we get other packs added soon (instead of the separate apps for sudoku variants). Gripes are the Google Play pop-up, the hiding of the Android controls (happy to give up some of my screen space for the navigation buttons and my clock...), and the relatively high battery usage (although that has gotten quite a bit better).

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.
