a selector operable by a player of the gaming machine to enable the player to select a feature which can be added to a base game played on the gaming machine, and to make a wager on the game, the wager including a base game component and an additional wager component, the additional wager component required by the game controller to be staked by the player in order for the player to be eligible for the feature, there being no guarantee that a benefit provided by the feature will eventuate merely by having staked the additional wager,

wherein when the benefit eventuates, the size of the benefit provided by the feature is dependent on the wager on the game; and

wherein the feature includes a series of free games and the number of free games provided by the feature is dependent on the size of the base game component of the wager.

2. The gaming machine of claim 1, wherein the size of the benefit provided by the feature is dependent on the base game component of the wager.

3. The gaming machine of claim 2, wherein the base game base is one in which a player stakes a wager on an outcome of the base game, and if a winning outcome occurs, the gaming machine awards that player a prize, and wherein the selector is further operable by the player to control the base game component of the wager by selecting both the size of the wager per outcome and the number of outcomes on which that wager is placed, wherein the size of the benefit provided by the feature is dependent on the size of the wager per outcome.

4. The gaming machine of claim 3, wherein the size of the additional wager is dependent on the size of the wager per outcome.
