Liked the features.

Liked: the various levels, second keyboard w note numbers.

Dislike: screen seemed small. The menu button cut into the number grid and the left side looked cut off as well.

Developer Response ,

Thanks for the review.

The cut-off look problem that you mentioned is a bug that affects new X series iPhones (X, XS, XS Max, and XR).

The next version of the app is in active development now and will be available in the coming days. This new version will bring new puzzles, new features and bug fixes for the mentioned problems.

Sorry for the inconvenience.

Loved it before the last update

I loved this app but since the upgrade, it no longer saves your game... so if you don’t have time to finish it then you have to start over every time. Also, it used to do a quick green highlight of a completed row or set of numbers that no longer happens.
For me not saving the game makes it difficult because I often play it when trying to kill time while waiting in a line or at the bank etc... now it’s annoying cause I feel like I’ve been playing the same level for a week because I keep getting interrupted and when I go back to the game, I need to start over. It’s making me look for another Futoshiki app

In two days Version 2.1 will be released on the App Store.
This new version will include a new game-saving mechanism and green highlights of row/column completion indicators.

Sorry for the inconvenience.

Much better than sodoku

The developer has fixed every complaint from users. So far every game is winnable without the frontal assault of trial-and-error.

That's very sweet of you to say! Thanks for sharing the love.
