Tapel Saga is a game that was developed by processing the "Malangan" mask visual, which is a work of Indonesian culture in the Malang area, East Java. This game gives a message about heroism, solidarity, community involvement and friendship so that it is hoped that through the Tapel Saga game, teenagers experience a real projection and are helped in responding to mental problems in their daily lives. This study aims to maximize the quality of the game by evaluating the usability of the game's user interface using the heuristics method. The research method was carried out using Neuroresearch which focused on the exploratory stage. In the exploratory research stage, the heuristic evaluation of the Tapel Saga game was carried out using a focus group discussion system so that there was an in-depth discussion between resource persons and game developers to find input and evaluate the ten criteria of the heuristic evaluation. The results showed that out of the ten criteria, 1 had been completed, while the others were minor fixes and still needed development. The results of the heuristic evaluation help evaluate the usability of the game interface so that it is of higher quality. Heuristic evaluation helps highlight potential usability issues early in game development.
