Problem solving using mole concept to express mass of a substance is one of the least learned skills of Grade 9 (G9) students of Katipunan National High School (KNHS) as reflected in the Mean Percentile Score (MPS) and test item analysis for the past two school years (2017-2018 & 2018-2019). Finding ways to improve this skill was one of the primary goals of the science teachers of KNHS. This study presented the effectiveness of “Gomoku”, a game based learning strategy in improving problem solving skills of G9 students in mole concept. Pre-experimental design was used in the study, of which pretest was given after discussion of the topic and posttest after the “Gomoku” intervention. Scores were treated using paired sample t test and adjectival ratings; Outstanding (90-100), Very Satisfactory (85-89), Satisfactory (80-84), Fairly Satisfactory (75-79), and Did Not Meet expectation (Below 75). Respondents of the study were 29 out of 51 randomly selected G9 Yakal students. Results revealed that posttest (m=5.414, s=1.21) was interpreted as satisfactory and greater than the pre-test (m=3, s=1.46), t (28) =-7.215, p= .05, which was interpreted as “did not meet expectation”. This implied that students perform better when exposed to “Gomoku” strategy; hence, “Gomoku” was recommended as alternative solution in improving students’ problem solving skills using mole concept to express mass of a substance.
