Sudoku ‪″‬ 4+

Review 2.0: I've been playing this version of Sudoku for several months now, and I want to thank the app developers for providing a version of the game for the adults! No funny animals, no storybook themes, no frantic distractions! Just a great app with plenty of boards to challenge you. For the greatest variety of challenge levels and no ads to distract you, spring for the "pay-to-play" version. It does not disappoint. Every player, from the beginner to a master's level player, will find a grid to their liking. Enjoy enjoy!

Review 3.0: As I said before! Simply, the best.

Review 4.0: I’m doing “medium” level grids, and am enjoying the challenge. Keep up the good work! As I said before, simply, the best!

Undoubtedly the best version of sudoku available on iOS. Clean and fast interface, quality of life tools that can be toggled easily mid-game, easy to make notes, auto population of notes that update automatically as you play, wide range of difficulty level, statistics on play history. I love this app, and I recommend it to everyone that likes/is interested in sudoku.

I wish dearly that they would also make other board sizes available (16x16, 4x4) but only because it’s such a drag to play other board sizes on other interfaces now that I’m used to this excellent app.

The game is well designed with one exception. When you fill in a number for a box as an answer, rather than a note of a possible solution for a box, it will automatically erase all conflicting notes on other boxes. So if I put “9,” for example in a box, it will automatically erase all other notes where 9 might be an answer in the same rows and columns. That is good! But it’s very easy to put down a number accidentally as an answer, when you only intend to list it as a note of possible answers. When you do that, and I promise you will accidentally do that more than once, a bunch of your notes on other boxes are automatically erased. If you don’t catch it right away, it will ruin that game.
