Abstract: The 668 students from 3 secondary schools were randomly selected and were given different Sudoku of 3 levels of difficulty namely: easy, medium and hard. All of them were given the same time to provide the different solutions. Hu used the same level of Sudoku in their research but this research extended to different levels with the aim of testing the popularity of the game among the students and gender differences in solving Sudoku. Findings showed that the game is more popular among the male and more female were unable to solve the game. The χ2-test statistic of the 3 tables showed that there is no association between gender and the ability to solve Sudoku game. In other to get a valid conclusion, the information from the 3 tables are combined using the methods prescribed by Radhakrishna and Everitt which showed that there is association between gender and the ability to solve Sudoku. Conclusion without combining the contingency tables would have produced an incorrect analysis and wrong interpretation.
