How to play Kakuro
Kakuro is similar to both sudoku and traditional crossword games.
Like a Crossword
Similar to crosswords, Kakuro has clues both across and down. When you put numbers in the vacant squares, the sum must equal the given clues. This is why the game is sometimes called 'cross sums'.
Like a Sudoku
Just like a sudoku, you cannot have the same number in a row or column. If a row is broken into 2 areas by a clue, then you can have the same number occuring once in each of the separate areas.
Other variations
Still looking for more puzzles? How about a variation on sudoku? Try Wordoku. Wordoku uses letters instead of numbers and has a hidden 9-letter word! For crossword puzzles, try Free Crossword PUzzles. 2 free crosswords (Easy, Hard) daily.

Talk about anything and everything, but nice to each other - you don't have to agree, but this is not the place for personal attacks. As Sir Paul McCartney said: 'I used to think anyone doing anything weird was weird. Now I know that it is the people that call others weird that are weird' (longer explanation). Enjoy!
This seems like a very tough one. Anyone want to give a hint on how they broke it?

The 14 can be quickly reduced to 2 options. One of them leads to a contradiction for the 20 in the bottom row.

Thanks Slartibartfast - For some reason, I'm not even getting the 14 reduced. I'm getting many reductions, and placing the 3,4 in the top row of 10, but I'm not getting the 14 to less than 4 options. Thanks for trying, but I'm missing something basic I think.

15:02 You're not alone; I couldn't reduce the 14 down to only 2 options either. Figured it out only by trial and error.

You need to account for the 'orphans'. The bottom box for 14 and the top box for 6 must add up to 11. That reduces both the 14 and 6 both to 2 options.

I already have the top box for 6 down to 1,2, so if I understood the 'orphans' concept, I would be cooking. Does anyone know of a web page that would explain what Mike is talking about? I'm not clear on the relationship for bottom of 14 to top of 6.

Add up all the vertical columns then subtract all the row totals - you get 11. Note all boxes were added, all but the two 'orphans' were not subtracted - so the orphans must sum to 11.

Thank you! I was looking at the wrong '6' and misunderstood. Now I understand - the total of entire board doesn't account for the 'orphans'. Many thanks for the help. This was a much better conversation than just seeing everyones times.

Thanks again to everyone that chipped away at my thick skull.

you've come a long way, UrBuddie (it's 2-14-12!)
I sure hope you don't get jet lag from all the traveling you did for this puzzle

Tough for sure. Picked a 14D combo and went all the way. I hate guessing.
