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!
