Friday Puzzle #60 - (h) ORu KakurOh!  
In recent years the USPC has had many good kakuro variations. I still remember the feeling of "I wish I'd done that" when I first saw the KakurOh in 2008. I had played with lots of tile variants for Mutant Sudoku and for the Mystery Hunt with skyscrapers but had yet to catch up to using the concept in a kakuro variant. The large squares in the KakurOh were a cool gimmick and ended up forming a really nice puzzle.

Unfortunately 2009 did not have a new kakuro variation (maybe people were still recovering from the eight puzzles thedan and I sprang at the 2009 Mystery Hunt) but here's hoping 2010 brings more fun.

Instructions: This puzzle is a combination of the 2007 and 2008 Kakuro gimmicks on the USPC. Each entry uses one of two possible choices for the sum of the numbers in that entry. Some large cells (in light gray) belong to multiple rows and columns but contain just a single number. The puzzle otherwise follows standard kakuro rules (enter a single digit from 1-9 in each cell, no digits repeat in an entry).

I'd rate this on the X-treme end of things, to match the X theme, but it is not impossible by any means.

Nice work, per usual. (Hang on while I make a TAoP comment template)

I bit the bullet and printed it out as I kept screwing up (I think) the {20/21} in the Pennsylvania region. It eventually worked out, and I came across some neat tricks...

1. The {11/14} and {9/7} in the lower right ended up working out based on there being only one number that could go in the shared big-cell. This is more of a facet of the puzzle-type itself, but since this type is new it felt clever.

2. I had a (56) pair in the 44 that led to a (56) pair in the {36/39} that forced it to be 36 which meant the (79) cell had to be a 7. If we were intended to come across that, that's a masterstroke.

Anyhow, I'll withhold my highest praise until you work sheep/wolves into a mutant Kakuro. This was very good nonetheless.
