5 stars: I can make the ads go faster by clicking very fast on the circle (usually right corner) or simply press very fast on the left (even if I don't see anything). Other than that, I can turn off the internet. I have a concern regarding certains ads. When there is a naked woman taking her bath and a man watching her (titled MAFIA), I don't think that it is appropriate advertisement.
5 stars: Addictive to play . I'm 3 hours passed my bed time. When I play, I have to stick with playing the one or two games a day if I can hold back. Not an easy task
5 stars: Really enjoy the option to auto fill when the solution becomes apparent.
5 stars: A challenge, finally. You can fall back on reg sudoku to help ease the challenge. How to intro is a great aid. My new favourite.\ud83c\uddec\ud83c\udde7\ud83c\udde8\ud83c\udde6\ud83d\udc3a
3 stars: Forced ad watching after each game in addition to banner. Premium is pretty cheap, but I don't like the app itself enough to pay to remove ads. On the one hand, it's well polished imo, but on the other, the way it handles mistakes (telling you immediately when you make one) can itself be used to solve puzzles. Also, make three typos and you have to restart the puzzle (though this can be disabled for some puzzles).
5 stars: Nice concept, perfect blend of sudoku and kakuro in one puzzle. If you're familiar with both, you'll make the jump to the expert levels in minutes. Very nice interface, minimal ads. Would love some more chall...
