UPDATE: I have lowered my rating from 5 to 1 star for the same reasons as stated previously. It's too bad because I used to really enjoy this app. Now I'm uninstalling. Good game. I usually play a few games each day. Something changed with a recent update and now it continually runs in the background. Force stopping it is only temporary. For this reason, I have lowered my rating from 5 stars to 3. Fix this issue and I will gladly go back to 5 stars. Ignore it and I will likely uninstall. I don't need the drain on my battery and the unnecessary usage of precious RAM.
It is a great app. But every now and then it will freeze up and turn itself off , but it will turn right back on to where you were nothing lost.
I have a galaxy 8+ and the edges cause a bit of trouble when selecting edge squares and numbers 1 and 9. Otherwise awesome.
Too many fullscreen popup ads, significant lag at times (via OnePlus2/Android), but most importantly max difficulty (lvl 5) is not challenging enough for an experienced player. Needs a lvl 6+
It's awesome... since class four, I have been trying to solve SUDUKU. But failed... Now it's easy to me... All credit goes to this app... love it...
Really enjoyed it. Love the notes capability. Wish it offered a variety of sudoku puzzles like sumoku, loco (squiggly), etc. All in all, developer(s) did a great job. Thank you!
