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

Developer Response ,

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.

Great Variation on Sudoku

This is a terrific game providing hours of game play. I would pay to have a save feature and a check feature. If you like sudoku, you should definitely try this.

Update: I find myself playing this game so often I paid to remove ads even though the ads didn’t bother me. I just felt like I owed something to the developers.

If I could make one suggestion for improvement it would be to change the error buzzer sound to something that wouldn’t scare the bejeezus out of me when I forget to turn the volume down. I don’t make a lot of mistakes but DO occasionally hit the wrong button.

Thanks for the review and also thanks for the support.

I will update the error sound with something more pleasant with the next update.

Outstanding Logic Game!!!

I especially enjoy the “Adjacent” variation. It’s hard to believe that some players are approaching 20 million points. The higher levels are very challenging and time consuming. I’m not sure I agree with one reviewer who stated that all levels can be won by logic alone. I sometimes use the guess strategy to see how far I can go without an error and backtrack when necessary, but only when I feel I have to. Kudos to the devs for such an elegant app!

Developer Response ,

Thank you for the wonderful compliments, Schubert!. So glad you like the adjacent version. Have a great day!
