A method and system for playing a terminal based lottery game having a slot machine theme includes assigning a defined set of objects to respective slot positions, the objects being unknown to game players. A player chooses at least one grouping of the slot positions from a plurality of possible groupings, and the system records the player's selection. For each of the slot positions, the system randomly selects an object from the set of objects assigned to each respective slot position such that a play set of the objects is generated for the player's grouping of slot positions. The player is awarded a prize amount that is a function of the number or combination of matches of objects within the player's play set. The methodology and system are particularly well suited for a poker slot machine theme game wherein the player's selected grouping corresponds to a poker hand, with the objects assigned to the respective slot positions corresponding to a poker deck of cards.
