A signal generator generates an award signal for causing the gaming machine to provide an award to a player in accordance with the special symbol combination displayed on the first display, when the determinant determines the first number of times is not less than the second number of times.

A user selects a product to be liquidated from a product provider and then designates to the transacting entity that reward points are to be used towards the purchase of the liquidated product. The transacting entity acts to decrease the number of reward points in the user's reward account by the required number of points. The reward account holder conveys consideration to the transacting entity equivalent to the par value of the reward points. The consumer obtains the product in exchange for reward points having a retail value equivalent to what he would have otherwise paid for the product, while the reward account holder is required to convey only the par value of the points. The product provider is able to liquidate the product and obtain payment equivalent to what it would otherwise have obtained in a prior art liquidation process, auction or trading environment.
