Background and Aims: The purposes of this study were to; 1) examine the results of using the Jeopardy Game to enhance English communication skills in all Thai primary-school learners, and 2) to determine the learners’ satisfaction after learning English for communication by using the Jeopardy Game. Methodology: This study employed both quantitative and qualitative methods for collecting data, which were then analyzed statistically for the results. The samples of this study were twenty-six primary school students learning in grades 4-6, who learned English for communication with the Jeopardy Game for a certain range of assigned time. The instruments included a set of appareled pre-tests and post-tests, a questionnaire, and classroom observation. The data of the pre and post-test and questionnaire were collected, and the dependent t-test, the mean, and standard deviation were used to analyze the quantitative data such as the test and questionnaire and the content analysis was used for the interview as the qualitative data. Result: The data analysis, indicated that the mean score attained by the participants in the post-speaking test significantly surpassed the mean score attained in the pre-test. Additionally, it demonstrated that the learners enjoyed playing the game the most. Secondly, the learners required higher difficulty-level gaming activities used in the classroom. Thirdly, the learners were encouraged to speak English well. After the learners had learned English by playing the Jeopardy Game, their attitude toward learning English improved to a highly satisfactory level in terms of encouragement, attention, and fear reduction. It also showed that the learners obtained positive attitudes at high percentages, which are desirable factors of effective learning. Conclusion: The findings indicated that the Jeopardy Game had a positive effect on English learners. The game opened up the opportunity for the learners to speak English in meaningful conversations and situations, which made them speak English with less fear and learn unintentionally throughout the gameplay focusing on the eagerness and desire to win the game. However, continuity of learning English with fun games in the classroom should be undertaken in a variety of topics and skills.
