You could have downloaded Kakuro Quest 1.0 for Mac from our application library for free. This Mac app is a product of Lost Sock Games. The application lies within Games, more precisely Board.
From the developer:
Kakuro Quest puzzles resemble crosswords or Cross Sums which use numbers instead of words. The aim of the game is to fill all the blank squares in the grid with only the numbers 1-9 so that the numbers you enter add up to the corresponding clues. When the grid is filled, the puzzle is complete. The Grid grows from 7X7 to 10X12.
