Works fine

Works fine for me on iPad mini 2, iOS 8.1.

Was pleased, now I’m a hostage to a crap update

I used to use this app pretty often, and I was really good at it. I purchased it when it was new in 2009. The latest update added ads, the “option” to update to pro; which I would assume is ad-free, but does nothing. So instead I’m forced to watch ads that i can’t click out of and mess with my timing on the app. Then there’s the lack of responsiveness on the app. It went from a fully functioning touch screen to smaller buttons and slow responses. For instance, when clicking a number triangle you see the options but you can’t click the done button because they decreased the size of clickable area and get stuck clicking it a few times until released. I used to enjoy this app but I won’t use it again until they fix this terrible update

Worst update

Actually hate them for updating this... was in my opinion one of the best kakuro games before via layout and design. Now the buttons are harder to hit, can’t visually see which are hit or not unless you strain your eyes, the timer isn’t working properly now either. So trying to improve to beat my time on master difficulty is basically null and void until they fix it. Also now the only way to not have the apparently 6 second win time on the difficulty is to reset my statistics beating the whole point of trying to improve my record...
