evaluating any symbols displayed in the at least one symbol display position enclosed by the subportion frame for a bonus;

evaluating symbol combinations formed from the symbols displayed in the symbol positions of the first grid for awards, the awards modified by the bonus and increasing the credit amount stored in the memory; and

detecting the input to cause the initiation of the payout via the cashout device.

6. The method of claim 5 , wherein the secondary grid includes one or more of the plurality of boundary elements positioned around a perimeter of the first grid.

7. The method of claim 5 , wherein the second grid overlaps the first grid to position at least one of the plurality of boundary elements adjacent to at least one corner of at least one of the symbol display positions of the first grid.

8. The method of claim 5 , wherein the bonus is an additional credit award that is added to the awards from the symbol combinations formed from the symbols displayed in the symbol positions of the first grid.

9. The method of claim 5 , wherein the bonus is a multiplier that is multiplies the awards from the symbol combinations formed from the symbols displayed in the symbol positions of the first grid.

10. The method of claim 5 , wherein the bonus includes remarking the at least one symbol display position of the first grid enclosed by the subportion frame prior to evaluating the symbol combinations formed from the symbols displayed in the symbol positions of the first grid for awards.

11. The method of claim 10 , wherein remarking the at least one symbol display position of the first grid enclosed by the subportion frame includes randomly remarking the at least one symbol display position of the first grid enclosed by the subportion frame.

12. The method of claim 10 , wherein remarking the at least one symbol display position of the first grid enclosed by the subportion frame includes remarking the at least one symbol display position of the first grid enclosed by the subportion frame with a wild symbol.

13. The method of claim 5 , wherein the bonus includes remarking the at least one symbol display position of the first grid enclosed by the subportion frame, where the symbol combinations formed from the symbols displayed in the symbol positions of the first grid are evaluated for awards both prior to and after the at least one symbol display position of the first grid enclosed by the subportion frame is remarked.

14. The method of claim 5 , wherein evaluating any symbols displayed in the at least one symbol display position enclosed by the subportion frame for a bonus includes evaluating the at least one symbol display position enclosed by the subportion frame according to a scatter pay method.

15. The method of claim 5 , wherein evaluating any symbols displayed in the at least one symbol display position enclosed by the subportion frame for a bonus includes evaluating the at least one symbol display position enclosed by the subportion frame for adjacent symbol combinations.

16. The method of claim 5 , wherein the plurality of boundary elements of the second grid include light elements, the light elements appearing unlit in an unmarked state and appearing lit in a marked state.

17. The method of claim 5 , wherein the plurality of boundary elements of the second grid include display elements, the display elements not appearing on the display device in an unmarked state and appearing on the display device in a marked state.

18. The method of claim 5 , further comprising:

marking one or more of the plurality of boundary elements of the second grid using a plurality of different markings types;

framing a plurality of different subportions of the first grid based on the marked different subportion marking types; and

evaluating symbols displayed in the symbol display positions of the first grid to identify winning combinations by independently evaluating each of the different framed subportions.

19. A gaming device comprising:

a display device configured to display a first grid of a plurality of symbol display positions;

a player interface;

a wager input device structured to receive physical items associated with currency values;
