A video slot game is described that increases a multiplier associated with each active pay line of the game independently of the multipliers associated with other pay lines of the game. Each line multiplier acts to multiply the winnings based on that particular line only. A multiplier for a particular line may be incremented for a current spin based on a wager outcome on that line in an immediately previous spin. A line multiplier may continue to increase as long as the player continues to win on that line. The increased line multiplier may have the side effect of acting as an incentive for a player to keep playing the game of chance, so as not to leave an unused line multiplier for another player. According to one variation, if the player does not win on a particular line, then the multiplier associated with that particular line may revert to a default level.
