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, weve 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 SecondDegree Black Belt volume, filled with puzzles that will provide a sly, absorbing test for even the best, most proficient experts.Youll go crazy for these super engaging brain bafflers!
