Abstract

Drawing on the contributions of two recent studies by Sugden (2007) and Luterbach, Rodriguez, and Milling (2010) in Spreadsheets in Education, this study illustrates that Excel-based Sudoku is an effective tool for teaching logical deduction. This study also illustrates some essential Sudoku techniques, all based on logical deduction. Relevant information from the Sudoku grid is extracted by using Excel features, thus making it easier for students to explore opportunities to apply suitable Sudoku techniques throughout the solution process.
