A lottery card marking apparatus provides a housing receiving a lottery card therewithin, with at least a top wall formed with a matrix of openings to coincide with free-positioned marking indicia on the lottery card. Optionally, the housing may include a rear wall with aligned apertures relative to the apertures to the forward wall to permit projection of a piercing instrument through the lottery card for marking purposes. Further, a modification includes a plurality of locking lug members slidably mounted to the right and left side edges of the housing to effect locking an alignment of the card within the housing during a marking procedure.
