The draw based lottery game is based on a symbol matching set of rules. A random selection of a subset of a deck of playing card indicia may be generated concurrently with a purchase of a lottery ticket having the instant lottery game and the draw based lottery game. A ticket printer prints the subset of the deck of playing card indicia on a lottery ticket according to an order of the random selection and a plurality of order indicia such that each indicium in the plurality of order indicia has an association with a playing card indicium in the deck of playing card indicia to indicate an order in the subset of the deck of playing card indicia.
