In one embodiment, the invention is a secondary game played concurrently with a conventional Keno game. In Keno, a player selects a plurality of numbers (e.g., 4-20) within an M×N grid (e.g., 8×10) of different numbers. A random number generator randomly selects a plurality of numbers (e.g., 20) in the grid. The player is then granted a first award based on matches between numbers that the player selected and the randomly selected numbers. As a secondary game played over the Keno game, for each number randomly selected, all numbers in the same row and column in the grid as the selected number are highlighted on the grid display. The player is granted a second award (e.g., free games) for each number not being in a highlighted row or column at the end of the Keno game. Variations of the secondary game are described. |
