I like the game, but I don’t like that we only get 3 mistakes, and on the 3rd mistake you have to watch a minute long advertisement to get back down to 2 mistakes. On any level harder than “easy,” it is an unrealistic expectation to stay under such a low number of mistakes in sudoku. Also, when starting a new game, sometimes you have to watch another minute long advertisement, but they don’t start the game after the ad. The games are timed as like a challenge to see if you can beat your best time, but the time starts while the ad is running, so by the time you get to actually playing the game, there’s already a minute on the clock. Overall a good game, but definitely still room for improvement.
