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!
orphans not needed, possibly greatest puzzle ever, requires solution heuristic I never saw before. Hint, it is to do with the orphans but you don't need to know what the orphans are.

actually, after solving 16 cells, it annoyingly needs orphans to finally resolve a dual solution, so not greatest puzzle ever, but still very a very good one

disregard last comment, doesn't need orphans. Greatest puzzle ever ...

there's a hidden 1,2 cross (that isn't really a cross, but behaves like one) that would form an illegal quad .......

ok, more hint ;-)

there's a 1,2 problem in the two 21D's. Possible locations are the 10A intersections, the 13A intersections, and the two orphans cells.

IF the 12's are in the 10A and the two orphans (eg NOT in the 13A intersections) THEN there's an unresolvable dual More...

Thanks Chris! Safe to say I never would have gotten that. A useful tool to use in future puzzles.

more hint:
26A = 123569 or 124568

12 3456 12 3456 3456 89

the fourth cell can't be 56, because Y!=12, so

12 3456 12 34 3456 89, eliminate 34 ...
12 56 12 34 56, use 5's X from 38A to eliminate 1345 solution from 13A

13A=1246, therefore Y=4 etc.

I just spent 8:40 eliminating the 6 from 26A/7D - only a couple cells from the (bitter) end !

Chris + 1. Brilliant Chris. Super puzzle and the 12s were certainly the key to solving the whole thing. Thanks.
