#40, 2007

FINALLY finished this book today. I started it more than a year ago, and it took me a while to work through all 240 puzzles. (Admittedly, there were months on end when it sat untouched). But this morning, I finished the last one. I didn't actually complete every single puzzle, but I did do all the "Diabolical" level ones. Decent puzzles, although at the higher levels, a fair number of these require a guess to go further, rather than being able to "logic" them all the way through. The text at the beginning, explaining how to work Sudoku puzzles, is also helpful for someone just learning these puzzles. ( )
