Like any game that can take possession of our students, playing Sudoku has all the elements of a good puzzle game: fun, excitement, and mental challenge. It is simply addictive - in a good and positive sense. However, in addition to the recreational values that Sudoku offers avid gamers, it also offers to develop more than your students' numerical skills. Cognitive Assessment Cognitive assessment of the grids, in particular the numbers given within the grids, develops the student's skill in identifying numbers in specific columns and retaining these numbers where necessary, in order to arrive at the correct numerical answer. Elimination By assessing which numbers are already given in particular squares in Sudoku grids, the student can employ the process of eliminating these given numbers to arrive at possible numerical answers. Logical Thinking With the numbers already given and the grids that have to be filled with numbers that have not yet been eliminated as the possible answers, the student can develop such logical thinking skills as deduction and induction. Analysis To arrive at the possible numerical answers, the student needs to analyze using the processes of elimination and trying out a number to see if it fits into the grid.
