This was one of my favorites until the last update that flashes whole screen ads during play that you have to clear. Very disruptive and part of the reason I payed for the app vs the free one.
The best Sudoku app My favorite feature is the multilevel hint. So if I get stuck, this reminds me to try and apply a technique but if that's not enough, it will show me how it applies. It can take me to a thorough tutorial on that technique. That is epic!
Far and away the best sudoku app of the dozens I've tried. The best user interface with the most options, and it's not even close. There are not video ads, only a few small banner ads, and they are as unobtrusive as possible. This is, without a doubt, the best sudoku app available.
Don't like the new popup menu It's ugly and it goes against the flow of one's eyes. The numbers are arranged in a left-right pattern while the menu is up-down. Sorry. You lose a star for this one.
Takes Away All the Hassle of Doing it on Paper This really is the best digitization of Sudoku making it very intuitive to figure out what can't go where without actually solving it for you.
The description says why he needs new permission To fix custom background bug. Developer you should update permission model for marshmallow so we can decline the permission of we don't use custom backgrounds
Switched to popup menus for the Game and Help buttons in play. This fixes problems with the Game and Help buttons not working on the Galaxy Note 5 and S6 edge+. Fixed problems with setting up a user menu background on newer devices. External Storage permission is now required to work around a bug in loading user menu backgrounds on a few popular devices. Now requires Android 4.0.3 or newer. Other minor bug fixes.
