***** MAY UPDATE ***** 20 new puzzles, 100 puzzles total! ------------------------------------- Presented by Cracking The Cryptic, YouTube’s most popular Sudoku channel, comes a new game based on one of their most popular videos: Miracle Sudoku. Miracle Sudoku features beautiful puzzles that at first glance look impossible to solve!! Indeed, some of our Miracle puzzles have as few as two givens digits (!) but you will find them all to be solvable with a bit of clever logic! At launch you will be able to play through 4 variants all of which make use of a non-consecutive restraint (ie neighboring cells cannot have two consecutive numbers in them). They are Non-Consecutive Sudoku, classic Miracle Sudoku (non-consecutive + knight + king restrictions), Non-Consecutive Thermo Sudoku and Non-Consecutive Sandwich Sudoku. Each of these variants has a unique feel which refreshes the logic you may be used to, especially in thermo and sandwich sudoku! As with our other games (‘Classic Sudoku’, ‘Sandwich Sudoku’, ‘Chess Sudoku’ and 'Thermo Sudoku'), Simon Anthony and Mark Goodliffe (the hosts of Cracking The Cryptic) have written all the hints for the puzzles. So you know that every puzzle has been play-tested by a human being to ensure that each sudoku is interesting and fun to solve. 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. Of course the difficulty is carefully calibrated to ensure lots of puzzles at every level (from easy through to extreme). Anyone familiar with their YouTube channel will know that Simon and Mark take pride in teaching viewers to be better solvers and, in these games, they always craft the puzzles with the mindset of trying to help solvers improve their skills. Mark and Simon have both represented the UK many times at 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 4 different variants with more hybrid variants coming post launch Hints crafted by Simon and Mark!

This type of logical puzzle was first seen in the Japan Puzzle Championship 2006 and is sometimes known as Doppelblock, or Smashed Sums. When played with pencil and paper, these puzzles can be hard work to solve. Sumaddle changes that by transforming the puzzles into interactive brain teasers that unfold before your eyes. Each puzzle has a unique solution. Finding the solution involves fitting the number combinations to the clues. The app makes it easy to view the possible combinations, you don’t need to do any sums in your head. Instead, you are able to focus on using logic to narrow down the combinations and find a fitting arrangement. The puzzles come in a range of sizes and difficulties, to suit all levels of skill and puzzling purposes. Choose a small puzzle to idle away a minute or two while waiting in a queue, or a big puzzle to give your brain some exercise during a coffee break! Some reasons why you will enjoy playing Sumaddle: • more than 150 puzzles are included for free • all puzzles can be solved with pure logic, no mental arithmetic required • the sophisticated built-in help can explain the logical reasoning at each step and also fix mistakes if you go wrong • the built-in help is completely free, use it as much as you like • works offline (great for long journeys) • a high standard of accessibility, including comprehensive support for VoiceOver • ad-free play - there are absolutely no ads!

Verdict

Miracle Sudoku's advantage is in-app purchases (none vs 15) and chart position (#52 vs unranked). On rating, ads and device support there is nothing between them.
