Each section of this book offers 22 puzzle types, with similar puzzle types grouped together and several puzzles referring to a tutorial in the back of the book. Hints help readers through sticking points, and at the bottom of each puzzle page a note tells readers where to find the solution for that puzzle. Solutions are provided in an interweaving order, so readers are unlikely to accidentally see the answer to the previous or subsequent puzzle.
Finally, each puzzle has three target times next to it: "Par" for a best guess on how long an average solver will take; "Expert" for how long an average participant at the WPC would take; 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 achieving the "Expert" time regularly, we highly recommend trying your country's national championships!
