Conceptis Kakuro – Intellectual entertainment

[Game] Conceptis Kakuro

Conceptis Kakuro  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.

Conceptis Kakuro user reviews :

I really like your sudoku, kakuro, tic tac toe (although I haven’t quite figured out its logic), and hashi? games. As I’m older my eyes however have a very hard time seeing the larger more difficult boards because the squares get much smaller and I frequently hit the wrong square because my finger is bigger than it is. I had the multi sudoku but couldn’t see anything. I tried to install it on my microsoft edge but couldn’t find it.

  • Sorry you are having a problem with the size of the boards. Please note that for Kakuro and MultiSudoku you can zoom the grids to see the numbers larger. On Hashi we are going to release this feature soon.

Enjoyable game! Play at my own speed and level with no ad breaks. No hints, but a “check for errors” button. A new free puzzle each week. This game keeps my mind thinking.

Excellent… Best app for Kakuro. Numbers repeated as notes delete themselves when they are used in another box in the row or column. Gave saved if you leave before finishing. Overall it’s my favorite to use.

Best Kakuro game I have ever played! Great interface, choice of challenge level, timer on or off, check for errors on demand… so customizable. Perfect!

Good interface, helpful instructions, fun game. Love the “check for errors” button.

Great app. More hard and very hard levels instead of the easy ones would be cool!

Great puzzles, the range of difficulty is appreciated.

Brilliant puzzles which get progressively challenging

I love that this is challenging. The hard puzzles take me a long time and I do have to check for mistakes. They seem inevitable for me at this point, although I have only completed a couple of those puzzles. I like the mental exercising.

Overall well done! The option to see possible solutions for each number is very helpful. I wish there was a semi-hard category. The mediums are too easy and the hard are too hard.

I love this game. It’s like suduko but using addition to make it a bit more challenging. You can pick a level your comfortable with. No interrupting ads either.
