ABSTRACT
Sudoku puzzles have been a mainstay in the United States since 2005. They are based on Latin Squares, which were popularized by Leonard Euler in the 18th century. Sudoku puzzles have an undeniable appeal. Their rules are easy to understand, yet puzzles can range from very easy to extremely difficult. Sudoku puzzles transcend language and culture, enabling the solver to pick up a Sudoku puzzle from Japan, Germany, India, or any place in the world and know the goals and rules of the puzzle. Some people mistakenly believe that Sudoku puzzles are mathematical because they use numbers. At the most basic level, students can be challenged as solvers to find solutions to the puzzles. The suggestions address the important logical aspect of the puzzles—the left-brain activities that are a natural part of most mathematical endeavors.
