BOWLING

Bowling is a sport or a game played by rolling a [ball] by hand. Bowling balls will be rolled into the pin numbering ten pieces which have been compiled into a triangular shape when viewed from above.
If all the pins dropped in one performance (throw) then it is called a strike. If the pin does not fall all at once then given one more chance to bring down the remaining pins. When the second throw is no longer called a left pin spare. If after the two remaining pins are still there then it is called an open frame (missed) all of which will determine the calculation of the numbers obtained in every game. Pin will return to normal prepared for the next frame.
Calculation method for sports figures are:

     Each game has 10 frames
     Each frame has 2 boxes representing two occasions throws
     Special on the 10th frame, which means there are 3 squares can have a chance 3 times throws
     The highest score in each game is called perfect 300 game
     Each frame strike will get extra points from the next two throws, while for spare an additional number from 1 throw next.
