It isn’t all I do all day, but now I have completed another 2 intermediate sudoku puzzles, plus a page of the bridges puzzles and a page of the inky puzzles. I like the fact that you can figure them out by logic and don’t have to resort to guessing, although I do a fair amount of guessing on the inky ones. Good thing I have a big eraser!  It was a great gift idea – I love it!
