This book's 151 puzzles are divided by approximate difficulty: training puzzles (about half of the book), national puzzles (25 percent), and world-class puzzles (25 percent). A helpful tutorial shows readers how to get started on a puzzle, and puzzles with sticking points comes with hints. The puzzle solutions are provided in an interweaving order, so when readers look at a solution they are unlikely to accidentally see the answer to the previous or subsequent puzzle. Finally, each puzzle has three target times: "Par" for an average solver, "Expert" for World Puzzle Championship participants, and the "Record" time, the best time logged among all of our testers. These times are, of course, just for fun, but if you find yourself getting times around the "Expert" time, we highly recommend trying your country's National Championships.
