Customer Reviews

Excellent game!

Love this app, allows me to keep my brain in check with fun and interesting puzzles. For people unfamiliar with kenken, it is essentially sudoku with the added twist that there are “cages” (oddly shaped boxes) whose result value must be met through a basic mathematical operation.

Only flaw, if any, in the app is that I’m wondering if some of the records on the leaderboards have been made with bots/cheats. Some of the puzzles have been solved in extremely, almost inhumanly fast times.

Friggin love KENKEN

I love this app and game. I’m obsessed. There are only three things that would enhance the app that I can think of

1. Enable offline kenerator. I play a lot of kenken on flights and often run out of puzzles to play

2. Force generate new puzzles. It seems that kenerator sometimes won’t generate new puzzles. It would be great if there was an option to enable kenerator to create a certain number of new puzzles with a specified difficulty and type

3. iPhone X support!
