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!

I thought I had eliminated 6-9 from a square in 35D, but that didn't work either! backstroke!

thanks big John - actually, it's helpful comments on many puzzles that have greatly helped me. Speaking of hopefully helpful comments, my +o-p approach:

1. Solved 10 bottom half cells with nada
2. using orphans, rule out 35D containing 245789 (LQN=879, but can't solve 39D).
3.

9:11 in 2018 and now I see how to do it faster.

Quick way using orphans (might be the same as what Don had in mind; not sure):

After filling in the ten easy ones, anything less than 6 in G forces {F,G,H,I}={2,3,4,5} and J=9. We know the 3 is in H, so the 5 is in G, so B=4, so E=9, contradicting J=0. Therefore (using orphans) 35D contains 6,7,8,9, so B=3, and on we go.
