What a treat! Sudoku is great but this adds a different challenge and is very enjoyable.

Great app for Ken-Ken and sudoku. Easy to use and navigate.

Tons of fun

Can be quite challenging. But that is what makes it fun.

Nice app for Kenken lovers!

Nice, clean, easy-to-learn interface. Wish there was a way to choose which operations to include or exclude from puzzles.

I have played many versions of this game and pencil marks are a big part of it. This game came with NO instructions on how to enter pencil marks, and after I figured it out, it was very inconsistent with adding additional marks. Numbers were constantly being added as the final value. I deleted the game rather than getting myself more frustrated and annoyed

Fun game

I like this game very much. It took a bit time to get used to, but it’s engaging!

Great way to keep my mind nimble. The game is well planned.

Nice Game - Minor improvements needed

I like it a lot better than Mathdoku. It’s user interface is much friendlier. But a couple of enhancements would bring it up to 5 stars. 1. Number each game and have a timer. This way you can go back to work on difficult specific games and try to beat your previous times. 2. Have an “undo” button to sequentially allow you to go back and make corrections. This, to me, is more useful than the “erase” function (x) - although you should still keep this also. The undo function would allow a ‘permanent’ number to be erased, but your previous pencil marks would then be visible again.

Well-designed KENKEN app
