Arcade operators use a combination of data analysis and strategic planning to decide where to place machines for maximum revenue. Key factors include customer traffic patterns, game popularity, and the overall layout of the arcade. High-traffic areas, such as entrances and near popular attractions, are prime spots for top-earning games. Operators also consider the balance between high-revenue games and filler games to keep players engaged. Regular performance reviews and adjustments ensure the setup remains profitable. By optimizing machine placement, arcades can enhance player experience while boosting their bottom line.
