An automatic pinsetter employing magnetically responsive bowling pins, an elevator mechanism employing magnetic means for retrieving bowling pins from a pit area adjacent an end portion of the bowling alley and for transporting the same to a pin discharge station above a transfer table. The pins are deposited by the conveyor and associated gates in a bowling array on the transfer table which is thereafter moved bodily beneath a pinsetting mechanism. The pinsetting mechanism employs magnetic means for elevating the pins in bowling array, the table is retracted from beneath the pinsetting mechanism, and the latter thereupon deposits the pins in howling array on the bowling alley. The pinsetting mechanism is also adapted to pick-up and replace remaining upright pins after a first ball has been thrown whether the pins reside in "on spot" or "off spot" positions. An improved bowling ball retrieval apparatus employing a suction cup is also incorporated in the pinsetter.
