Abstract
A gaming terminal provides at least a portion of at least one prize in the form of at least one or more free game rounds. A benefit may be calculated as the difference between the value of the prize if paid out in coins or other monetary value and the value paid out as free game rounds. In one aspect, the benefit is redistributed in the paytable, preferably so as to provide a game in which the overall, long-term averaged payback amount is unchanged by the process of converting monetary payouts to free game payouts and redistributing the benefit thereof.
