A method, comprising the steps of: in response to a single bet by a bettor, presenting to the bettor in a visually-perceptible form a rectangular array of randomly-generated symbols arranged in an array of cells on a computer display, the array of cells having a primary pay line consisting of a primary group of cells that pays a primary prize to the bettor for one or more arrangements of symbols in the primary group of cells of the primary pay line, and one or more secondary pay lines each consisting of a respective secondary group of cells, at least one cell of each of the one or more secondary pay lines being off the primary pay line, the one or more secondary pay lines having respective secondary prize odds for arrangements of symbols in the respective secondary group of cells of the one or more secondary pay lines, the secondary prize odds being lower than the primary prize odds for arrangements of symbols in the primary group of cells of the primary pay line, at least one of the one or more secondary pay lines having cells that are not collinear or not contiguous with each other, wherein the primary prize odds and the secondary prize odds are each a ratio of a payoff value to a value of the single bet; and paying the bettor a prize calculated based at least in part on a wager by the bettor and on the arrangements of symbols in the primary pay line and in the one or more secondary pay lines.
