Summer Games is a sports game that lets up to eight players compete in a series of Olympic events with a summer theme. The story revolves around each player taking turns competing in various events, with the goal of winning the gold medal.
The gameplay in Summer Games is similar to other Epyx games. Players can choose a country to represent and then take turns competing in different events. They can decide which events to participate in sequentially, select a few events, pick just one event, or practice an individual event. The available events vary slightly depending on the Sega Master System platform and may include pole vault, platform diving, 4x400 meter relay, 100 meter dash, gymnastics, freestyle swimming, skeet shooting, 100 meter freestyle, and rowing.
