I almost passed on this FAOTD after reading that the app automatically opted users into data collection (Flurry). I can't stand it when PAID apps require intrusive permissions, display irritating advertisements, etc.
I decided to see for myself if the app seemed sketchy, and I'm glad that Idid; Openfeint and Flurry analytics have been removed entirely.
The app itself is a good implementation of Sudoku -- both the gameplay and appearance are very customizable.

[BIG THANKS TO AMY]

A little over a year later, this app made its second debut as the Free App of the Day. What's Changed? Something for the better.

When I saw this as the Free App of the Day the second time around, I found this review once again, and noticed another reviewer, Amy, reported that OpenFeint and Flurry were both removed. The second thing I noticed was my review on which the headline said that 'Hidden "Flurry Analytics" Spies On You', so decided that I needed to take another look to see if my original review still held value.

I'm pleased to report that Amy is indeed correct. A year later, Flurry is gone and OpenFeint is *dead* (long may it stay that way). Hooray! Too bad the developer never contacted me sooner, though.

The game is still more difficult than they are rated, but for other than "very easy" that's probably a good thing. There are some really fun variants in this version, and the mechanics are fantastic. As I said in my original review, this is a 5-star game that was hammered for having OpenFeint and Flurry Analytics. With those gone, I'm happy to revisit and update this review to give it the five stars this app deserves.

(And *THANK YOU* to Amy for reporting this first!)

Cheers,
Robert~

Hidden "Flurry Analytics" Spies On You
[09JUN2013]

One star removed for openfeint, but at least the option to disable it was there, and the developer let us know in the product's description that it was there.

Since this is a full-featured sudoku game with every bell and whistle, I planned on giving that star back for quality and thoughtfulness.

EDIT: Looks like OpenFient and Flurry have been removed from the game. Kudos to the developer!

Original review:

This app is your basic Sudoku puzzle game, but it also has seven different variants, such as Color Sudoku, in which each each color must have a unique number in addition to the usual rules, and Jigsaw Sudoku, which has oddly-shaped squares.

This game has one of the largest Settings menus I have seen in a long time. Just about everything is customizable, from the level of help it gives you to the colors and fonts the app uses.

The list of features in this game is enormous. It has a full help system which can analyze the puzzle difficulty, tell you want techniques are needed to solve it, check for mistakes, fill in the pencil marks, or show your next move. You can save multiple games in progress, and you can bookmark a particular layout so you can try a possible solution, then undo it all if you made a mistake, useful on harder puzzles where there may be several paths to follow.

While this app does have OpenFeint, it asks when you start the app for the first time if you want to enable or disable it; it can also be disabled in the Settings menu. The app also has Flurry Analytics, which can be disabled in Settings.

My sole complaint about the app is there is no explanation for the different game variations, but fortunately they are pretty easy to figure out.

The app works perfectly on my Motorola Xoom tablet and my HTC Evo 3D phone.

Update: This app has just been updated and it no longer contains Flurry Analytics and OpenFeint. With the removal of these two items I have raised my review from the original 3 stars to 5 stars. I played multiple games this morning and this game is probably the best performing Sudoku apps I have played. Thanks to the developers for listening to the reviewers and improving the product.

I love Sudoku and this will become one of my favorite time killing apps to play.

my original title:
I love Sudoku but not the spyware apps in this program, make sure you turn them off before you play the game!

I was excited to see this app this morning as I love Sudoku and play it almost every day. After I downloaded this app I immediately turned it on only to be hit up right off the bat with OpenFeint. Thankfully it let me opt out of OpenFeint but I then looked at the settings and found Flurry Analytics. Flurry Analytics is software that can data mine your use of the app and forward the data to the developer. I have listed its functionality below for you to see. Fortunately the options let you opt out of sending data to the developer but I just wish they would have been more up front with it and given you a chance to opt out of sending data before you began playing the game. Do we have to check every app for every intrusive bit of data collection before we play it?

I still gave the game 3 stars as I love playing Sudoku but this could have been a 5 star game if they had told us openly about Flurry Analytics and given us a chance to opt out on the first screen we saw.

Flurry Analytics functionality per their web site:
