Abstract
At least a method and an apparatus are provided for efficiently generating non-redundant machine-generated quick pick lottery game entries. A computer file is created that includes every possible combination of number groups eligible for being selected for a particular lottery game. The every possible combination within the file is randomly shuffled to create a randomized list of non-redundant entries. A file index with a file index pointer is assigned to the randomized list of non-redundant entries. The file index pointer is set to an initial position in the randomized list of non-redundant entries. Each non-redundant machine-generated lottery game entry is generated by only sequentially incrementing or only sequentially decrementing the file index pointer in the randomized list, and outputting the each non-redundant entry indicated by the file index pointer to a ticket request device.
