Good game. Some solve fairly easily, others I just can't do. I haven't figured out what the color shading is all about. Sometimes I get a group of numbers shaded with a purple background. What's this trying to tell me? Some numbers are highlighted with a blue background. A help reference section would be great. Sometimes if I've spent way too much time on a puzzle, it would be nice to confirm my progress with a check feature.

Nice apps. The problems are quite challenging. My suggestion is the apps should provide solution so that people can check what is their mistake if they could not get solution. I could nkt solve some problems and quite sure my logic is correct but no result is consistent. So I kind of doubt whether the problem is correct or not

Really good game, some ads but not too bad. Never had hard any issues

Very good game slowly but surely getting my time down on these puzzles esp the extreme levels!

Played this game for years. Since updating the game I can no longer access any of the higher levels I have completed. I am stuck doing all the levels again as I haven't completed the last 10 levels even though when you click on all the levels they say "you win" restart this game or play others. If this is not fixed soon I will just find another game as I am not doing these levels all over again.

Getting a network error on both Wi-Fi and data that won't let me start the game.

This app is so tiresome, dull and unimaginative. The lack of multiple cells selection and summation is suspicious. Why do I have to manually notate, and/or add up a dozen cages? Maybe to make solving the puzzles unnecessarily more difficult, so you'd have to rely on the hints that you get for watching 30 SECONDS ad each! And the quantity of ads is unbelievable. This seems like a rip off!
