Rules of the Professional Bowling
The professional bowling consists of ten parts (frame). A player throws the ball twice in each of the first nine parts if all ten pins are not struck during the first throw. In the tenth, the player throws three throws, in case the first throw strikes all ten pins (strike), or two throws strikes ten pins (spare). Each part must be completed by a player in the general order.
Unless all ten pins are strike on the first throw, the number of pins dropped is indicated on the monitor in the upper left corner of the square to capture the corresponding frame of the game. The number of pins shot during the second throw is fixed in the upper right corner of the same square. If no pins are struck during the throw, a dash (-) is entered at the appropriate position. The total result after each throw is displayed at the bottom of the square to capture the corresponding part (frame).
When all the pins are knocked down during the first throw, a strike is counted. A strike is marked with an (X) in the upper left part of the square that marks the corresponding frame of the game. A strike is scored by ten points plus the number of pins shot in the next two throws. The maximum result is achieved by shooting 12 strikes in a row and is equal to 300.
If all the pins are left after the first throw but they are knocked down during the second part of the game, the spare will be counted. The spare is marked with a diagonal line (/) in the upper right corner of the square marking the relevant part of the game. Spare is scored for the number of points scored by the pins, plus the number of pins shot by the next throw.
A mistake is recorded when a player throws his foot or crosses the approach zone and the track separating the throw line during the throw, and when the player touches a part of the track or a structure behind the throw line with any part of the body. A throw is considered unfinished until the same or another player takes a seat on the opponent for the next throw. If a player makes a mistake intentionally, he is credited with zero pins and the player loses the right to extend the part of the game (frame). If a mistake is recorded, the throw is considered valid, but the pins shot down with that throw are not counted. If a player is entitled to additional throws in the same part of the game (frame), the pins shot in the throw in which the mistake was recorded must be rebuilt.
