5 stars: A great challenge but if you go slow and watch what you are doing , it then becomes a fun experience that you do not want to quit .You now want to increase the challleng, no pencile..no hints just you so outlook.come think and enjoy. Never forget ,only 9 numbers, down,up and 9 in a square.I hope all. of you out there will try and enjoy. Start with pencile and then try a pen...Never gets discouraged.
5 stars: I have only played one puzzle, the daily challenge. It was fun and I was able to utilize the information from the tutorial.
3 stars: Don't like the ad. placement. Before and after is ok not during the game.
5 stars: Downloaded after becoming a fan of cracking the cryptic on YouTube. Not as fun as watching the videos but a lot more challenging.
4 stars: Quite enjoyable. It would be nice, though, if the hint button asked you to confirm that you want a hint. I often bump it by accident. I never want hints as I like to solve the puzzles on my own.
4 stars: The game is great but I am really getting tired of Google turning up the volume on the ads and not giving us a mute button. I understand the needs for the ads but not blowing out our ear drums. Too bad the game would get a 5 but for the headache from the noise. UPDATE... Still has a a good number of ads, but I can live with it. 3 to 4 stars is because the are more ads with mute buttons. I can now watch them without the pain. Thank you.
3 stars: I was enjoying this app until I made three sill...
