Description

Kakuro are addictive logic puzzles best described as number-crosswords. Using pure logic and simple add/subtract calculations, these fascinating puzzles offer endless fun and intellectual entertainment to puzzle fans of all skills and ages.

Each puzzle consists of a blank grid with sum-clues in various places. The object is to fill all empty squares using numbers 1 to 9 so the sum of each horizontal block equals the clue on its left, and the sum of each vertical block equals the clue on its top. In addition, no number may be used in the same block more than once.

The game includes zoom for easier solving of large puzzles, as well as helpful features such as showing possible sum combinations in a block, showing the sum remainder of a block, and using pencilmarks to make temporary placement of numbers in the grid.

To help see the puzzle progress, graphic previews in the puzzle list show the progress of all puzzles in a volume as they are being solved. A Gallery view option provides these previews in a larger format.

For more fun, Conceptis Kakuro includes a Weekly Bonus section providing an extra free puzzle each week.

So much fun and reasonable cost

This game is well developed, lots of nice UX touches that make it fun to play. I really like being able to buy a batch of puzzles for a reasonable cost, rather than have it messed up by ads or need to pay a monthly subscription (which I probably wouldn’t.)

Once I get into the Very Hard category, I usually need to do some guessing - it would be cool to have some solving hints (not the answers, but a principle I could use in certain situations to figure it out).

But I bet I could find that info out there if I decide to research it.

I really like the feature where I can auto-pencil all the hint possibilities at once. I like to figure out the hint possibilities on my own, but if I mess something up and need to erase them all, it makes it a lot less tedious not to have to go through all that logic again, and just re-add them properly.

The undo and redo are really nice features also.

Developer Response ,

This issue is actually a bug in iOS 14, and that's why you saw it as soon as you did the update. We found a workaround and will release an update soon which will fix this issue.

Next best app to Primo Kakuro

Let me preface this review by saying that Primo Kakuro was hands-down the best Kakuro app out there. Unfortunately, the developers have chosen not to upgrade their app to work with the new iPhone iOS. Perhaps they’ve decided to concentrate on their knitting apps (???!!!). They hadn’t added any more puzzle packs in a long time anyway, and I’ve been through them all. So I was forced to find a new app. After trying pretty much all of them I’ve settled on the Conceptis version as the best. After getting used to the interface, it works almost as well as Primo Kakuro. My only complaint is that it doesn’t allow you to use different colors for the pencilled-in numbers. Without this feature, the “Very Hard” puzzles are nearly impossible to complete without guessing, which kind of defeats the object of the game. Other than that, it’s an excellent substitute. And they seem to be adding more puzzle packs constantly, so hopefully we can enjoy it for a long time to come.

Could a five star

I reserve five stars for knock your socks off perfection. Thank you to the developer of this game for allowing the essence of this wonderful game to come through. Occasionally, during a “very hard” version I feel like I have to take a guess, so it’s still teaching me about possible combinations and how to think outside the box.
I love the immediate feedback when I’ve completing a row or line incorrectly. Also, the ability to see possible combinations and reducing the options as I fill in part of the solution. However, sometimes when I tap on the clue it shows me the row when I tried to select the column or vice versa. I thought it just might be that my fingers are too wide and I’ve tapped incorrectly, but it’s happened even when I’ve carefully tapped with a pinky, and doesn’t happen when im selecting a box. First world problem which is resolved by tapping the cue a second time.
Enjoy!
