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!

1. How many cells could you do with nada? 10 for me.
2. Can you make certain deductions regardless of two options? I did this twice.

Easy with possibilities and orphans.

Nada, just have to work out the mental chain

Don: 10 cells with nada for me, too. Orphans make it easy to finish from there.

See below for my approach. I'd like to know if Joe's approach was different:

1. 14A is 4523 or 4532, thanks to 2 of the nada cells.
2. my deductions w/o orphans:
a. Regardless of 14A, 4x in GHLM.
b. 25A: C<>4, so A=9 or B=9 (several cells are the same either way).

Needed to run 1 possibility to solve.

the chain in C took only 51 seconds from the 10-cell saved position

big John, after 1st 10 cells, there were 3 values for C, right? Did you find just one chain for C?

First steps toward nada:

After filling in the first 10 squares:

There are, in the downs, four missing 1's and two missing 4's.

Of these six missing entries, one appears in 16 across, two in 17 across, at most one in 10 across, and at most one in 25 across. Therefore at least More...

Remainder of nada:

But 3 in C gives (on considering 10 and 7 down, and remembering no 3 in 5 across) 3 in Z, so can't have 3's in both 17 and 16 across.

Therefore 1 in A and off we go.

thanks willo, ingenious approach (especially count of missing entries). Because 5A contains 2 of missing entries, either 10A or 25A must contain a 1 (but can't be both). Incorrect option in either row makes the other row impossible.

Nada, running a chain from upper left corner.

Don: Thanks. Actually, my 'remainder of nada' comment no longer makes any sense to me, but my earlier comment still works to get started, and you've got it nicely finished off.
