Ten-pin bowling 5 on their first ball and 3 on their second, the open frame would be worth 8 pins.) The maximum score in ten-pin bowling is 300. This consists of getting 12 strikes in a row in one game (one strike each in frames 1–9, plus all three possible strikes in the tenth frame), and is also known as a perfect game. In 1934, British anthropologist Sir Flinders Petrie, along with a team of archaeologists, discovered various primitive bowling balls, bowling pins and other materials in the grave of a protodynastic Egyptian boy dating to , very shortly before the reign
Ten-pin bowling it is damaging the integrity of the sport. Before 1970, nearly all bowling balls had a hard rubber surface. As the coatings applied to wood lanes changed from softer lacquer to a harder urethane in the early 1970s, the first polyester balls became widely available. Subsequent changes since the early 1980s — particularly with urethane surfaced and later "reactive" resin or composite ("particle") surfaced bowling balls—have been altering the physics of how the ball rolls and strikes the pins. Coupled with synthetic lane surfaces and advanced oiling machines presenting the opportunity to lay out lane oil patterns that make targeting
