display on the electronic display device at least one main array with a plurality of main positions arranged in a plurality of main rows and columns,

randomly transform a special position of the plurality of main positions into a sub-array having a plurality of secondary positions arranged in a plurality of secondary rows and columns,

determine an outcome for the sub-array in which the plurality of secondary positions is populated with respective secondary symbols,

in response to the outcome for the sub-array, determine a special symbol associated with the special position of the main array, the special symbol having a predetermined association with the sub-array outcome,

display on the electronic display device any determined special symbols for each of the randomly transformed special positions,

populate the plurality of main positions in the main array with a plurality of main symbols, the main array including the plurality of main symbols populating the main positions and any determined special symbols populating the transformed special positions,

evaluate the main array to determine if a main winning combination is achieved, and

receive, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.

2. The gaming system of claim 1 , wherein at least one of the main array and the sub-array includes respective spinning reels.

3. The gaming system of claim 1 , wherein each main position of the plurality of main positions includes a respective spinning reel.

4. The gaming system of claim 1 , wherein the special position occupies a space extending across a single row and a single column of the plurality of main rows and columns.

5. The gaming system of claim 1 , wherein the special position occupies a space extending across at least two rows or two columns of the plurality of main rows and columns.

6. The gaming system of claim 1 , wherein the outcome for the sub-array includes at least one secondary winning combination.

7. The gaming system of claim 6 , wherein the at least one secondary winning combination is randomly selected from a plurality of secondary winning combinations, the plurality of secondary winning combinations being associated with respective special symbols, the at least one secondary winning combination being associated with the special symbol.

8. The gaming system of claim 1 , wherein the special symbol is a game-enhancement parameter.

9. A gaming system, comprising:

a gaming machine primarily dedicated to playing at least one casino wagering game, the gaming machine including an electronic display device and one or more electronic input devices; and

one or more controllers configured to:

detect, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance;

initiate the casino wagering game in response to an input indicative of a wager covered by the credit balance;

in response to receiving the wager, display on the electronic display device a main array with main array positions and having a plurality of main reels,

spin the plurality of main reels,

in response to the spinning of the plurality of main reels, randomly display on the electronic display device one or more sub-arrays at one or more, but not all, of the main array positions, the one or more sub-arrays having a plurality of secondary reels,

while the remainder of the plurality of main reels is still spinning, spin, stop, and evaluate the plurality of secondary reels of the one or more sub-arrays to determine one or more special symbols for populating at least one of the main array positions,

in response to determining the one or more special symbols, stop the spinning of the remainder of the plurality of main reels and populate the main array positions with primary symbols and the one or more special symbols,

evaluate the main array to determine if a main winning combination is achieved, the evaluation being based on both the primary symbols and the one or more special symbols, and

receive, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.

10. The gaming system of claim 9 , wherein each of the main array positions includes a respective reel of the plurality of main reels.

11. The gaming system of claim 9 , wherein at least one of the one or more sub-arrays has sub-array positions, each of the sub-array positions including a respective reel of the plurality of secondary reels.

12. The gaming system of claim 9 , wherein the one or more sub-arrays is a single sub-array and the one or more special symbols is a single special symbol, the special symbol populating a single position of the main array positions.

13. The gaming system of claim 9 , wherein the one or more sub-arrays is a single sub-array and the one or more special symbols is a single special symbol, the special symbol populating two or more positions of the main array positions.

14. The gaming system of claim 9 , wherein the evaluation of the plurality of secondary reels determines at least one secondary winning combination.

15. The gaming system of claim 14 , wherein the at least one secondary winning combination is randomly selected from a plurality of secondary winning combinations, the plurality of secondary winning combinations being associated with respective special symbols.

16. A method of operating a gaming system, the gaming system including one or more controllers and a gaming machine, the gaming machine primarily dedicated to playing at least one casino wagering game, the gaming machine including an electronic display device and one or more electronic input devices, the method comprising:

detecting, via at least one of the one or more electronic input devices, a physical item associated with a monetary value that establishes a credit balance;

initiating the casino wagering game in response to an input indicative of a wager covered by the credit balance;

displaying on the electronic display device a main array with main array positions and having a plurality of main reels;

spinning, via at least one of the one or more controllers, the plurality of main reels;

in response to the spinning of the plurality of main reels, randomly displaying on the electronic display device at least one sub-array at one or more, but not all, of the main array positions, the at least one sub-array having a plurality of secondary reels;

while the remainder of the plurality of main reels is still spinning, spinning, stopping, and evaluating, via at least one of the one or more controllers, the plurality of secondary reels of the at least one sub-array to determine one or more special symbols for populating at least one of the main array positions;

in response to determining the one or more special symbols, stopping, via at least one of the one or more controllers, the spinning of the remainder of the plurality of main reels and populating the main array positions with primary symbols and the one or more special symbols;

evaluating, via at least one of the one or more controllers, the main array to determine if a main winning combination is achieved, the evaluation being based on both the primary symbols and the one or more special symbols; and

receiving, via at least one of the one or more electronic input devices, a cashout input that initiates a payout from the credit balance.

17. The method of claim 16 , further comprising populating, via at least one of the one or more controllers, a single position of the main array positions with a single special symbol of the one or more special symbols.

19. The method of claim 16 , further comprising:

in response to the spinning of the plurality of main reels, randomly displaying on the electronic display device at least one other sub-array at another one of the main array positions, the other sub-array having another plurality of secondary reels;

while the remainder of the plurality of main reels is still spinning, spinning, stopping, and evaluating, via at least one of the one or more controllers, the another plurality of secondary reels of the other sub-array to determine another special symbol for populating another one of the main array positions; and
