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!

It is a Nada

My nada:

1) Fill in 10D, Q, W, X

2) 7+5+9=21 and A+B+E at least 6, so G+H+K at most 15, so I+J at least 14. But no 5 in J so 7 in J. Also, I=8 or 9.

3) Want to rule out I=9. This would give A+B+E=8. Can't be 1+3+4 (else no way to fill in D, since {O,R}={1,2}), so must More...

Nice solution, Willo. Especially the initial proof J=7. I've never before though to have used the idea that three cells in line must be 6 or greater. useful.

(In case it wasn't clear in my earlier post: You fill in X by noticing {O,R}={1,2}, and there are 3's in both 5D and 4D, eliminating all but one choice for X.)
