Gaming methods and devices that include a primary game and a bonus game. In the primary game, one or more paylines of an array are selected. One symbol from a predetermined set is then randomly assigned to each image site of the array. Awards are granted when certain combinations of symbols appear on one or more of the paylines that were selected by the player. A bonus game may be awarded for each selected payline of the primary game on which a triggering event occurs. In each bonus game, one or more of the symbols along the corresponding primary game payline may be randomly replaced with other symbols from the predetermined set. If multiple bonus games are awarded, the bonus games may be played sequentially. An additional bonus event may also be awarded if a triggering event occurs in a predetermined or prespecified location of an array of image sites.
