Everyone loves sudoku puzzles, finding them impossible to put down. The only problem: having enough sudokus to solve! Created in the United States, these addictive conundrums were originally called “Number Place” puzzles until their recent rise in popularity in Japan, where the name translated as sudoku. However, in a true sudoku, unlike a “Number Place” puzzle, the grids are symmetrical. This trait makes for a more elegant solve. Every puzzle included inside is symmetrical, which is not always the case in other sudoku books. In this “Martial Arts Sudoku” series, we’ve indicated the skill level necessary to complete each book in the same way Japanese karate levels are ranked: by different colored belts. This is the Second-Degree Black Belt volume, filled with puzzles that will provide a sly, absorbing test for even the best, most proficient experts. You’ll go crazy for these super engaging brain bafflers!

Sudoku’s a big craze even with children—and this huge collection will keep every puzzle-loving kid busy and happy for days. It features a simply phrased three-page introduction—longer than usual—to teach all the basics and get new solvers up to speed. Then, one after another, come the sudokus, which start easy and become progressively harder as kids build their skills and proficiency. There are hundreds of 6 x 6 puzzles, smaller than the standard, plus tons of adult-sized9 x 9 sudoku, too. Of course, all the answers are included, so if a child runs into some difficulty, he or she can see how each puzzle is solved.

For all you clever CosmoGIRLs!—Fun puzzles for a brainy workout.Start solving, CosmoGIRL! These chunky little paperbacks are hipper and nicer looking than any other puzzle books out there—and just perfect for tossing right into a stylish bag to take anywhere. Created by the unequaled Frank Longo, both books are graded with three different puzzle levels: Easy Start, Getting Smart, and Pretty Sharp. The hotter-than-hot sudoku collection features invaluable skill-improving tips and hints. The other collection showcases wordoku, which uses the same principles but with letters instead of numbers—and solvers are given a “word-key” to help discover a hidden word. The magazine’s millions of readers will never be more psyched to reach for their No. 2 pencils!
