Classic Sudoku from Beetles Studio is arguably the most polished version of the game on the App Store. It doesn't try to reinvent the wheel; instead, it focuses on the user experience. The 'Notes' system is intuitive, automatically removing numbers from notes once they are placed in a row or block, which significantly speeds up high-level play.
The difficulty scaling is well-judged, ranging from 'Easy' for beginners to 'Expert' for those who enjoy X-Wings and Swordfish techniques. The Daily Challenges are a nice touch, giving you a reason to log in every day to collect trophies. It’s clean, ad-supported but not overly intrusive, and includes a solid hint system that explains the logic behind the move rather than just giving you the answer.
Available on: iPhone, iPad, iPod

10 new puzzles, all 100 puzzles are out now!
-------------------------------------
Presented by Cracking The Cryptic, YouTube's most popular Sudoku channel, this is the brand new “Classic Sudoku” game that their viewers have been requesting for the last two years!
Simon Anthony and Mark Goodliffe, the hosts of Cracking The Cryptic, have assembled a most extraordinary collection of sudoku puzzles. The sudokus in the game cover a wide range of difficulty with something for everyone - and also require an incredible range of techniques to solve them efficiently! Each of these special puzzles had to qualify for inclusion in the game by passing our rigorous play-testing - a test that NO other sudoku game on the market would pass. This play-testing ensures that a human being has actually thought about the journey you, the solver, will go on as you work through the puzzle. No computer testing here!
Indeed our more advanced puzzles have been carefully designed to showcase some of the diabolical techniques in an intuitive way with the aim of helping solvers UNDERSTAND the patterns involved.
In Cracking The Cryptic’s games, players start with zero stars and earn stars by solving puzzles. The more puzzles you solve, the more stars you earn and the more puzzles you get to play. Only the most dedicated (and cleverest) sudoku players will finish all the puzzles!
Featured authors include (obviously) Simon and Mark but also some other authors who have produced popular puzzles on the channel!
Mark and Simon have both represented the UK many times in the World Sudoku Championship and you can find more of their puzzles (and lots of others) on the internet’s biggest sudoku channel, Cracking The Cryptic.
Features:
100 beautiful puzzles
Many themes to choose from
