Ten-pin bowling is a type of bowling in which a bowler rolls a bowling ball down a wood or synthetic lane toward ten pins positioned evenly in four rows in an equilateral triangle. The objective is to knock down all ten pins on the first roll of the ball, or failing that, on the second roll. People approach modern ten-pin bowling as either a demanding precision sport or as a simple recreational pastime.
