From the IB, it seems online solving will be enabled. Will there be some practice puzzles online before the test? LMI's sudoku solving interface will be reused for this test. Practice puzzles will be available to solve online before the test (hopefully much sooner). |

Location: India | Practice PuzzlesThe authors have been kind to pin together some practice puzzles into a pdf. Here is the link to download them all.

Hideaki, it seems so. I am sorry, but had not enough time to resolve all practice puzzles before publishing. I hope you will enjoy the competition.

You are right. I will change these two numbers in the first row 18 -> 17 and in the second row 27 -> 28. I´m not the author of this puzzle so maybe Matus modify it in a different way :)

I don't know whether it's because I plain suck at Kakuro or the puzzles are terribly imbalanced toward the hard side, but having only 50% complete while I usually score around 70-80% sounds a bit unusual...
The solving paths seem to require some bruteforce in most puzzles I attempted? Or otherwise require a lot of mental additions. (I used scratch paper.) Or I just miss much more elegant solving paths.
Anyway, good test. |

Very nice contest. I especially loved how the solve path plays out for some of the puzzles.
@chaotic_iak: Most of the puzzles worked out just fine for me. I scored nearly 700, and would have gotten another 100 if I haven't botched solving the big odd/even. On the other hand, I am quite comfortable with Kakuro. Ya, there are some additions for sure, but I always take that as a part of Kakuro, as long as it isn't too ridiculous.

All the puzzles are solvable by plain logic. Yes, some of them are harder, but no bruteforce is needed. As you can see, quarter of the participants have solved (nearly) everything, some of them in incredibly good times.

Location: France | This was a fun contest! The puzzles were very nice -- but I don't think the point distribution was very good. In many cases the big puzzle barely took me any more time (if any) than the small one despite being worth a lot more points. |

Location: Czech Republic | Well, I don't know if this was the issue with online version only (as I did the online version and haven't downloaded the PDF) but I found mistakes in odd-even small. There were two "equations" that didn't fit my numbers in the table but afterall I submitted them (even I knew my equals are lower than the wanted ones) and it was considered right...
(my different equations were 36 (the original one in online version test - third from the right in the top row) - mine got 34; and 35 (original one - second from the bottom in the left column) - mine was 33.)
I just thought if it was a general mistake or something else. |

The kakuro is considered right when you have the two marked rows or columns correct (as to pdf version when you only copy these numbers). You were lucky that your mistake was out of these rows/columns. You had probably some small mistake... |
