Okay, most of you already know tsmaster, but for those of you who don't:

I have this really smart friend, Dave, who recently wrote a computer program which creates Cross Sums puzzles (also known as Kakuro). I helped him beta test some of the end results and had a ridiculous amount of fun doing so (in fact, this was how I spent a good chunk of my time at the beach).

Well, he's finally put the end result on the market. If you like number puzzles, please go take a look.

I'll be buying a few copies myself, just as soon as the spiral bound copies go on offer.

ETA: I did not know that I actually have a credit in the book until *after* I posted this, I swear. *blush*
