Mathematics-based game learning is made as attractive as possible in order to increase students' motivation and interest in learning, besides that this game can increase students' critical thinking patterns. This research uses a mix method with a combination of sequential explorstory design model with a thiagardjan development model through the 4D realm, namely define, design, develop and desseminate in experimental research using nonequivalent control design with the results obtained from the pretest value functioning to determine initial knowledge and posttest to determine knowledge after being given treatment.development of carring community-based mathematics learning devices using operational games in increasing students' learning motivation and its effect on critical thinking ability Based on the the Asymp Sig (2-tailed) is 0.000, so it is smaller than 0.05.
