Abstract

A method and apparatus for use in gaming activities, such as in a slot machine. A first grid comprising a plurality of elements overlayed a second grid comprising a plurality of elements is presented. At least some of the elements of the first grid and the second grid are marked. Marked elements of first grid are then used to form a subportion, the subportion boundary enclosing an area and having a correspondingly marked element of the first grid at each corner. Payouts are issued for marked elements and element combinations of the second grid within the subportion. The payouts may be administered according to a pay table.

First claim

The invention claimed is:

1. A wagering gaming device comprising:
a display device configured to display a grid of a plurality of symbol display positions;
a wager input device configured to receive physical items associated with currency values;
a memory device configured to store a credit balance and to store data related to a plurality of game reels, the data including arrangements of symbols associated with each of the game reels; and
game circuitry configured to:
receive an input signal from the wager input device indicating receipt of a physical item associated with a currency value;
increase the credit balance stored in the memory based on the currency value associated with the received physical item;
receive a wager signal to initiate a first gaming event of a game of chance in response to placement of a wager, the wager decreasing the credit balance;
mark one or more of the symbol display positions of the grid by spinning a first plurality of the game reels and stopping the first plurality of game reels to display symbols in the symbol display positions;
automatically frame at least some of the symbol display positions in the grid with boundary elements independent of inputs from a player;
while maintaining the symbols shown in the symbol display positions framed by the boundary elements, re-mark the remaining symbol display positions of the grid that are not framed by the boundary elements;
evaluate symbol combinations formed from the symbols displayed in the symbol positions of the grid for awards after re-marking the symbol display positions that were not framed by the boundary elements to determine a game outcome for the first gaming event; and
provide awards for the first gaming event based on the evaluation of symbol combinations, where the provided awards increase the credit balance stored in the memory.

2. The wagering gaming device of claim 1 , wherein re-marking the symbol display positions that were not framed by the boundary elements includes spinning the first plurality of game reels to display new symbols in the respective symbol display positions that were not framed by the boundary elements.

3. The wagering gaming device of claim 2 , wherein the game reels spun during the re-marking of the symbol display positions that were not framed by the boundary elements are independent game reels spinning only within the respective symbol positions in the symbol display positions being re-marked.

4. The wagering gaming device of claim 1 , wherein re-marking the symbol display positions of the first grid that were not framed by the boundary elements includes:
providing a second plurality of game reels; and
spinning the second plurality of game reels within the grid to display new symbols in the respective symbol display positions that were not framed by the boundary elements.

5. The wagering gaming device of claim 4 , wherein providing the second plurality of game reels includes using predefined new game reels.

6. The wagering gaming device of claim 4 , wherein providing the second plurality of game reels includes modifying the first plurality of game reels.

7. The wagering gaming device of claim 6 , wherein modifying the first plurality of game reels includes adding wild symbols to at least one of the first plurality of game reels.

8. The wagering gaming device of claim 6 , wherein modifying the first plurality of game reels includes adding bonus symbols to at least one of the first plurality of game reels.

9. The wagering gaming device of claim 6 , wherein modifying the first plurality of game reels includes adding multiplier symbols to at least one of the first plurality of game reels.

10. The wagering gaming device of claim 1 , wherein the game circuitry is further configured to evaluate symbol combinations formed from the symbols displayed in the symbol positions of the first grid for awards before re-marking the symbol display positions of the first grid that were not framed by the boundary elements.

11. A wagering gaming device comprising:
a display device configured to display:
a first grid of a plurality of symbol display positions; and
a second grid of a plurality of boundary elements, the plurality of boundary elements positioned at least between some of the plurality of symbol display positions of the first grid;

a wager input device configured to receive currency or currency based tickets, the currency or currency based tickets establishing a credit balance, the credit balance being increasable and decreasable based at least on wagering activity;
a cashout device configured to receive an input to cause an initiation of a payout associated with the credit balance;
a memory device configured to store the credit balance and a plurality of symbols; and
game circuitry configured to:
receive a wager signal to initiate a game of chance in response to placement of a wager, the wager decreasing the credit balance;
mark one or more of the plurality of symbol display positions of a first grid by randomly selecting symbols to appear on the plurality of symbol display positions;
initially mark one or more of the plurality of boundary elements of the second grid, the boundary elements being marked independently of the symbols displayed in the first grid;
frame at least some of the symbol display positions in the grid using at least some of the initially-marked boundary elements of the second grid to define one or more framed symbol display position;
while maintaining the symbols shown in the symbol display positions framed by the initially-marked boundary elements, re-mark the remaining symbol display positions of the grid that are not framed by the boundary elements;
evaluate symbol combinations formed from the symbols displayed in the symbol positions of the grid for awards after re-marking the symbol display positions that were not framed by the initially-marked boundary elements; and
detect the input to cause the initiation of the payout, via the cashout device.

12. The wagering gaming device of claim 11 , wherein the game circuitry is further configured to re-mark one or more of the plurality of boundary elements of the second grid after the remaining symbol display positions of the grid that are not framed by the initially-marked boundary elements have been re-marked.

13. The wagering gaming device of claim 12 , wherein the game circuitry is further configured to frame additional symbol display positions in the grid using the re-marked boundary elements of the second grid to define additional framed symbol display positions.

14. The wagering gaming device of claim 13 , wherein the re-marked boundary elements are marked in addition to the initially marked boundary elements.

15. The wagering gaming device of claim 14 , wherein the game circuitry is further configured to:
frame additional symbol display positions in the grid using the re-marked boundary elements of the second grid; and
re-mark the remaining symbol display positions of the grid that are not framed by either the initially-marked boundary elements or the re-marked boundary elements.

16. The wagering gaming device of claim 11 , wherein the game circuitry is further configured to evaluate symbol combinations formed from the symbols displayed in the symbol positions of the grid for awards after re-marking the symbol display positions that were not framed by either the initially-marked boundary elements or the re-marked boundary elements.

17. The wagering gaming device of claim 16 , wherein the game circuitry is further configured to combine any awards associated wi
