Settings Bug, Not iOS 11 Compatible

UPDATE: Found a workaround for on/off settings toggle bug! After moving toggle it will retain OPPOSITE setting when menu is closed. (To turn off an option that is on, toggle switch to off and then back to on and exit the menu. Option will be off and toggle will be in off position when the settings menu is reopened.)


This was my favorite game for years. I have all of the expansion packs and by now have worked all of the puzzles several times.

The app worked perfectly for me, even on iOS 10. Because I already had the settings configured how I like them, I never tried to change anything to experience the bug where settings changes will not take effect. However after uninstalling this app and then later restoring it under iOS 10, all of the settings returned to their default (on) and cannot be changed.

I will also caution that the app launches with a warning that it will not work at all with iOS 11 unless the developer updates it. Unfortunately there does not appear to be any sign of life from the publisher since five years ago in 2012. Sadly it looks like this app is not long for the world.

Best Kakuro App... Except...

This is by far the best Kakuro app I've found. Great guess functionality that lets you make notes on cells you're unsure of, lots of puzzles and different levels. However, since iOS 10 it won't let you turn off a number of the settings, which is driving me nuts. Music on, squares alerting you to mistakes, etc. if the settings would stay as I select them, this is a five star game.

Great at what it does, for now

I've been playing this game for years, and am just about ready to buy another set of games. Please don't let it die with the next iOS update.
