Conceptis Kakuro

by Conceptis.

Price: Free

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.

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