A secondary game operable on a gaming machine top box includes visual representations of a plurality of bingo cards formed of five columns, each column corresponding to a letter in B-I-N-G-O. The secondary game also includes peripheral spaces on the top box corresponding to each letter on each card. Qualified players, e.g. those making a maximum bet on the base game, cause the secondary game to operate whereby one of the peripheral spaces is selected. A letter causes the column on the card associated with that letter to be lit; however, the cards must be completed sequentially so that the `B` column must be lit before `I` and so forth. Completely filling out one or more of the bingo cards results in a selected award associated with that winning card. In a preferred embodiment of the invention, a bonus script is built that predetermines the number of plays made and the bonus amount received. The player then simply plays out the script until the bonus amount is one.
