1 point a bowling pin
in the 1830's is when they started to ban 9-pin bowling in Texas, so many changed to 10 pin.
In any of the variants of 10-pin bowling (including Duckpins or candlepins), each pin is worth one point. However, when you are scoring a strike (all pins down on first ball) or spare (all pins down on 2nd ball), the scoring is more complex. For a spare, the score is 10 plus the number of pins knocked down on the first ball of the next frame (so, for example, a spare followed by a 7 count would be 17) For a strike, the score is 10 plus the number of pins knocked down on the next two balls thrown (so, for example, a strike followed by a 7 count then a completed spare would be 10+7+3 = 20). The most points that could be scored in a frame would be a strike followed by a strike, followed by another strike, 10+10+10 = 30. This gives us the maximum possible bowling score of 300 (10 frames, maximum of 30 pins in each). If a strike or spare is thrown in the 10th and final frame, the bowler immediately throws one (in the case of a spare) or two (for a strike) bonus balls, called "extra frames". These frames do not score on their own, they only serve to determine the extra pins for the 10th frame's mark.
