Abstract
A lottery game method and associated system include offering a plurality of different draw-type lottery games to players, with each of the lottery games having a different game theme and respective rules of play. Lottery tickets are issued to the players in the different lottery games, with each lottery ticket having a grid of uniquely identifiable positions displayed thereon. The number of grid positions may vary between the different lottery games. In a single drawing event, grid positions are randomly and sequentially drawn in a number so as to encompass all of the different types of grids for the respective different lottery games. The sequential order in which the grid positions were drawn is provided to the players and prizes are determined for winning lottery tickets in each of the different lottery games as a function of the order in which the grid positions are sequentially and randomly drawn.
