I first got interested in Kakuro puzzles when I spotted a book on these curious
beasties and in the front was the peculiar claim that they couldn't be created on
a computer. That sounded like a challenge to me so here we are.
Just like the Sudoku and Gogen puzzles, every day,
I put a brand new, unique, symmetrical Kakuro
puzzle on this web site for you to print out and solve and it doesn't cost
you a thing.
Unlike the Sudokus, Kakuro puzzles take a bit more solving
so I have provided web pages with the unique number
sets and all number sets
to help. Also, I have made a PDF
file of all 502 valid Kakuro sequences (right) with their
eliminated numbers and sums so that you can see them on one page - the printout
is a bit small but weigh up the gain of having only one sheet to look at.
In addition, I have also written a tutorial
so even if you are a complete novice, you can have a go and realise the
enjoyment of doing these puzzles. Additonally, I have formatted the pages
so that they can be viewed on a smartphone easily.
Again, these puzzles are produced by my computer, only for this site,
using a computer program that I wrote myself in Perl. The solver part of my
program uses logic and maths, it does not use brute-force. As a result of this,
you will be able to solve them using just logic and maths.
