I love quick “brain games” as a way to take a quick break but without turning off my brain, using using it in a different way. There’s a bunch of games that fit this category well, but perhaps none is as long-standing or popular as Sudoku, the excellent number-based puzzler. And of all the ways to play Sudoku on your iPhone or iPad, you can’t do better than Sudoku Master Edition: Logic for its excellent gameplay and Apple-featured design. Read to learn more and enter a special giveaway sponsored by the developers!

Sudoku is a classic game that needs no fixing, but when you complete a Sudoku on an iPhone or iPad rather than paper, there’s some things you can do to make the experience even better. The developers have thought these through so that Sudoku is even better on iOS than on paper. For example, when you fill in a square with a number, Sudoku ME can automatically remove that number from your notes in the square’s corresponding box, line, and column. Similarly, Sudoku can optionally fill in the last number in a box, line, or column to speed up that last no-brainer entry. Likewise, Sudoku can prevent you from entering a wrong number. All of these are optional settings–you can be entirely purist, mimicking a paper experience–but the subtle combination of those settings is that you spend more time solving the Sudoku puzzle and less time doing boring menial tasks. I find Sudoku way better as a result.

Whether you’re a Sudoku expert or beginner, whether you like assists or are a purist, Sudoku ME is the app for you, with five levels of difficulty (let me tell you, “Master” is wicked hard) and several different modes: Classic, Zen, Lightning, and Mistake Mode. The developers worked hard so that the defaults are excellent and you can jump right in playing–but they also enabled a bunch of features you can individually customize: 26 fonts, custom grid line weights, dozens of colors, Dark Mode, multiple game board sizes–even 13 different app icons so you can match your home screen style! All beautifully and tastefully done, with an excellent eye towards a clean design.

That beautiful design is probably why Apple has featured them as Game of the Day multiple times and in over 40 different countries and featured the developers in a “Meet the Developers” story! The developers aren’t resting on their laurels, though. In fact, since they last sponsored MDM Deals a bit over a year ago, they’ve pushed out 20–yes, twenty–updates to the their app, adding in features like optional Daily Reminders, Screen Always On, a new game difficulty algorithm, Apple Pencil 2 double-tap support, and more. Put simply, I’ve never seen a better Sudoku game on iPhone.

Sudoku Master Edition: Logic is free download and play, with unobtrusive ads you can remove via a single IAP. I’m excited to say that the developers are giving away an IAP unlock code 100% free to five lucky MDM Deal fans.
