I'm running out of sudoku puzzles and thinking about getting this book. Are the puzzles the sort that you can solve purely by logic, or do you have to do a lot of trial and error?
You could honestly do it either way. There is a fair bit of logic with it. I almost never have had to resort to trial and error. But there're not exactly mind engaging, hard core, logic puzzles where you have to use different strategies with each any every puzzle. But I do find them pretty engaging.
