  Handicap: A number added to a "scratch score" to form a "handicap score". Generally, handicaps make lower-average bowlers have handicap scores that are close to handicap scores of higher-average bowlers, to make matches more evenly competitive.
  Head pin: The 1-pin.
  (The) Heads: The front part of the lane, roughly from the foul line to the arrows. Precedes the midlane and back end.
  Heavy: See high. Opposite of light.
  Hook: The second of three phases of ball motion—following the skid phase and preceding the roll phase—characterized by maximum change in ball direction. Hook is mainly caused by a ball's frictional engagement with a lane in its side rotation (rotation not in the same direction as the ball's overall forward motion); hook is also affected by dynamic imbalances in the ball's internal structure (core design and orientation).
  High:  Adjective describing shots that impact the pins undesirably inside from center pocket. Opposite of low.
  High flush: A strike in which the ball apparently impacts high of center pocket, but still sends all ten pins to the pit (a flush).
  House ball: A non-custom ball, generally conventional grip with polyester ("plastic") coverstock, provided by bowling facilities for use by patrons.
caption: The hook is the second of three phases[19] of ball motion.
