Ten-pin bowling Bowling Championships. Ten-pin bowling has an international ranking system, as with many professional individual sports. This ten-pin equivalent is known as the World Ranking Masters and is made of three vast tours: the European, Americas and Asian bowling tours. Other minor tournaments, although major in their respective countries, include Britain's prestigious BTBA Nationals (BTBA National Championships), the Brunswick Ballmaster Open, Brunswick Euro Challenge in Greece, ETBF European Youth Championships, the European Gold Cup and the Mediterranean Challenge Cup. The world's premier amateur event is the WB/WTBA World Championships (World Bowling) which has been running since 1954 and is now held
Five-pin bowling bowlers use a number of terms to denote the results of a throw: All modern bowling centres use automated pin-setting machines (first used in 1957) to reset the pins after each ball is thrown. In five-pin, two types of pinsetters are used—"string" and "free fall". The "string" pinsetter is known for each pin having a string attached to the head. These pinsetters were first invented in 1963 and are characterized by a string being attached to the head of each pin. This type of pinsetter has a low operating cost, so it is the most commonly used type of pinsetter.
