This research aims to prove that using text twist game improves the seventh-grade students' vocabulary mastery at SMP Negeri 1 Labuan. This research applied the quasi-experimental research design. The population of this research was the seventh-grade students of SMP Negeri 1 Labuan which consisted of 3 classes. The samples were class VII A as the experimental group, and class VII C as the control group. This research employed cluster random sampling to select experimental and control groups. In this research design, a pretest was conducted to both experimental and control groups before the treatments, while posttest was conducted after the treatments. The data were analyzed statistically to find out the significant difference in students' achievement in pre-test and post-test by using t-counted formula. The result of the data analysis indicates, there was a significant difference between the result of the pre-test and post-test. It could be proved clearly by seeing the mean score of both tests results. The mean score of the experimental group was significantly improved from 36.90 to 66.10. Meanwhile, the control group's mean score was improved from 36.74 to 45.91. Then, by applying 25 degrees of freedom (df) and 0.05 level of significance, it indicates the t-counted (2.74) is higher than the t-table (1.68). In conclusion, using the text twist game technique improves vocabulary mastery of the seventh-grade students of SMP Negeri 1 Labuan.
