Uma Musume Pretty Derby is a mobile and PC simulation game developed and published by Cygames. Players train anthropomorphized horse girls — characters inspired by real-world racehorses — guiding them through rigorous training regimens, races, and competitions in pursuit of championship glory.\n\nThe core gameplay loop revolves around a training simulation mode where players manage stats, relationships, and race performance over a career scenario. Between races, players develop bonds with their Uma Musume characters, unlocking story events and boosting performance. Strategic planning during training cycles is essential to producing top-tier racers.\n\nThe game is part of a broader multimedia franchise including anime and music, but the game itself stands alone as a deep training sim with gacha elements for collecting new horse girl characters. The Japanese version launched in February 2021 and surpassed 30 million downloads across Asia. The global English version released on June 26, 2025 across iOS, Android, and Steam.
