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!

Go way beyond difficult, with the hardest, most brain-busting sudoku you've ever seen! Calling all sudoku-solving diehards: with every puzzle requiring upper-level strategies, this collection packs even more of a punch than our previous Beyond Black Belt Sudoku. Get ready, because you'll encounter common advanced techniques with curious-sounding names like XYZ-Wing, Finned X-Wing, Sashimi X-Wing, Swordfish, Jellyfish, Gordonian Rectangle, and Gordonian Polygon. And you might find some tricky new things here, too, from Grouped X-Cycle and Simple Grid Coloring to 3D Medusa and Bi-Value Universal Grave. The sudoku generally become increasingly difficult as the book goes along, from "pretty darn hard" to "excruciating." Are you up for the challenge?
