new edition of the Huge Killer Sudoku book

Hello,

I just published a 2nd edition of the "Huge Killer Sudoku" book:

e-book at:

http://www.lulu.com/shop/patrick-min/th ... 39824.htmlpaperback at:

http://www.lulu.com/shop/patrick-min/th ... 40059.htmlIt has 25 fewer "warmup" puzzles, and 25 more difficult puzzles

(so a total of 75 difficult puzzles)(for each of these you can score 9 points on the site)

I had to do a

*lot* of space saving measures, to get the total page count to 168 pages,

to keep the paperback price below $10... (!)(which means that of the $9.99 price, $9.98 goes

to the publisher

)(as discussed earlier, the ratio is better for the download version).

The paper version now has an ISBN, so hopefully after about 6-8 weeks the book will also be on Amazon.

**If you've already bought the 1st edition of the book:** please send me a note, with your username, and I'll send you

the new edition (do make sure you've submitted at least one solution of the book first).
