(iv) in response to the randomly selected outcome being the at least one free spin bonus outcome, provide a plurality of free spins and display a plurality of free spin enhancements, each of the plurality of free spins enhancements having a value associated therewith, the values remaining constant for the plurality of free spins;

(v) enhance an outcome of a subsequent free spin based on a player selection of at least one of the free spin enhancements for the subsequent free spin; and

(vi) deactivate the selected at least one of the free spin enhancements after the subsequent free spin.

5. The gaming system of claim 4 , wherein a sum of the selected multiple free spin enhancements enhances the outcome of the subsequent free spin.

6. The gaming system of claim 5 , wherein a product of the selected multiple free spin enhancements enhances the outcome of the subsequent free spin.

7. The gaming system of claim 1 , wherein, when all of the at least one of the free spin enhancements have been selected and have enhanced a subsequent free spin, all subsequent free spins are enhanced by a predetermined default enhancement.

8. The gaming system of claim 7 , wherein the predetermined default enhancement equals a multiplier of one.

9. The gaming system of claim 1 , wherein, when all of the at least one of the free spin enhancements have been selected and have enhanced a subsequent free spin, all remaining free spins are inactivated.

10. A method of operating a wagering game comprising:

displaying a plurality of free play enhancements in response to the randomly selected outcome being the at least one bonus outcome, values of the plurality of free play enhancements remaining the same for the plurality of free plays;

enhancing an outcome of each of the free plays based on a player selection of at least one of the free play enhancements for each subsequent free play;

deactivating the selected at least one of the free play enhancements after selection; and

awarding the enhanced outcome of the free plays to the player.

11. The method of claim 10 , wherein the step of enhancing an outcome further comprises the step of selecting a plurality of the free play enhancements for at least one of the free plays.

12. The method of claim 11 , wherein the step of selecting a plurality of free play enhancements further comprises the step of determining a sum of the plurality of free play enhancements and,

wherein the step of enhancing an outcome further comprises the step of enhancing an outcome of the subsequent free play by the sum.

20. The method of claim 18 , further comprising the step of adding the at least two multipliers, in response to the at least two multipliers being selected, to produce a sum and wherein the sum is used to enhance either the first outcome or a single subsequent free spin outcome, whichever occurs immediately after the selection of the at least two multipliers.
