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!
