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!

Great app, with a much nicer interface than the other "single theme" apps of the series. In particular, being able to use 9 colors like on the web app was overdue. It would be great if the devs could move the other individual apps to packages in this one. One bad point is the menu which is incredibly slow, sometimes taking close to a minute to select another puzzle. Fortunately the puzzles themselves are responsive.

I like it. The puzzles are beautiful, though some are insanely difficult. I've made it all the way through several CTC apps and still I could be stuck on one of these for days. Good or bad, IDK. But... I cannot select all of one number or color and there's no button to remove all coloring or all pencil marks, e.g. from a selection. Also when I hit delete in a cell it deletes all pencil marks AND coloring. I just find it really clunky and wish it was the same as the other apps or the web app.

A vast improvement over the initial release. There are still improvements that could be made, but I'm very happy with this as it is. I'm updating my review from 3 to 5 stars. I miss the zero and letters, but the red number tool is very handy. Anyone using this app should investigate the settings. This really is an app where personal preferences make a big difference in usability. There were a number of settings I needed to change before I was satisfied.
