I used to love this game and have played it countless times to exercise my brain. I would have given it a 5 star rating but recently it all changed because the increase in the number and frequency of ads became unbearable like in so many other games. With some you spend more time watching ads than you do playing the game. Oh well it was fun while it lasted. Just realised if I turn off my Wi-Fi I don't get so many ads so I've hibrn it one more star!

good basic sudoku app. i find the limited time events entertaining enough and a positive addition to the app. however, i find the way points are awarded based on puzzle difficulty is annoying and frustrating; why do easy difficulty puzzles give 1 point but "extreme" difficulty puzzles only award 2? its a small thing but quite annoying

Good: Only sudoku app I've found with both undo & auto candidate removal. Bad: It needs a harder difficulty level where I can work on advanced techniques. Even "Extreme" seldom requires x-wing etc, it's almost always simple elimination. Bad: I accept ads but the ones with sound on by default are a killer issue. I can't play anywhere that sudden, unpredictable audio would be a problem. Bad: I would buy the app but the price is secret and I won't put my credit card down for an unknown amount.
