The quick answer- The Game is played between two four-member teams who use stones with different colored handles. Each game consists of ten ends, which r similar to innings in baseball. During an end, each team member alternates throwing stones toward a circular target area, called the house, the center of which is approximately 93 feet away. Only one team scores points per end. The team with their stones closest to the center of the target area, called the button, gets one point for each stone between the button & the opposing teams nearest stone. After each end is completed, play is switched to the house at the other end of the sheet.
