Abstract: Slot machines utilize one or more pay lines on which a combination of symbols are lined up to determine whether a particular pay line wagered is a winner according to a pay table that shows winning combinations with associated pays. Players are able to place wagers or bets of varying amounts on the pay lines and the machine pays out based on the amount wagered and the number of winning pay line combinations displayed. The present invention enhances game play by offering players the opportunity to choose whether to wager on a pay line that runs right-to-left or left-to-right without changing the probabilities of winning. Or, alternatively, of offering the player the option to wager on pay lines that run in both directions with a weighting of the win probabilities.
