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.
