About this game

Fill empty squares so each block sums up to the number on its left or on its top. 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.

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.

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.

No ads, good interface, hard puzzles. The only criticism I have is the price of adding extra levels. I'd be willing to pay $5-10 to get all the puzzles, but it'd take hundreds of $ to get everything. The free content is very good though, so I recommend downloading it at least for that!

This app is okay, but lacks functionality. There are no game options. Because the game automatically removes possible numbers from rows and columns around a new # entry, one must use the back function. If you enter a #, then change your mind, for instance, you need to just go back. The back button does help to test ideas. Big points off for having no way to tell the game to not automatically indicate mistakes. Difficulty is good at the hard level only for experience solvers.

You can tell the game to not automatically indicate mistakes by turning off the "Show errors" option in the app's Settings.

I love most things about this game. My only complaint is that often on Hard, and always on Very Hard games I get stuck and have no way to figure them out. I won't even attempt the Tough and Challenges versions. It would be awesome if there were something that could show me what I am missing so I could improve my skills. I'm certain it's a related to being able to see several moves ahead. I'd like to learn how to do the harder puzzles.
