To make playing even more enjoyable, all ads, including banners, are now eliminated if you make any purchase at all. It's our way of saying "Thank you!"

The last update caused delays on some devices. This should take care of the few of you who had problems...sorry.

- Though we're sure you don't ever make mistakes, we still thought we should improve the Undo and Redo functions...so we did. - A few users complained about infrequent random crashes. Now, they should happen even less frequently (or hopefully not at all!). - The Notes function, both for "Possible" and "Impossible" entries, is now even better. Just double tap or triple tap...or select the green or red notepads on the bottom.

- We fixed a small bug that caused rare crashes for some users. - For those who can't get enough of KenKen, your in-app purchases should now appear immediately...no more waiting. - A great new Auto Save feature is now available under Settings. Turn it on and you'll NEVER lose any of your hard work. - Remember...you can always select your own music to play in the background while KenKen'ing. Select your songs under Settings.
