4. The method of claim 1 , further comprising updating, by the game controller, a meter stored in the memory based on the first game evaluation and the second game evaluation.

5. The method of claim 1 , wherein the first subset comprises a number of symbol display positions that is equal to a number of symbol display positions comprising the second subset.

6. The method of claim 1 , wherein each part of each column has a same number of symbol display positions.

7. The method of claim 1 , further comprising displaying, by the game controller, a barrier separating the first subset from the second subset.

8. An electronic gaming system comprising:

a display configured to display a wagering game;

a player input interface configured to receive a player input;

a credit input mechanism including at least one of a card reader, a ticket reader, a bill acceptor, and a coin input mechanism, the credit input mechanism configured to receive a credit wager, the credit wager initiating play of a base game;

a tangible, non-transitory, computer-readable memory; and

a game controller communicatively coupled to the memory, the game controller configured to:

select a plurality symbols from a plurality of reel strips stored in the memory;

display, on the display, the selected plurality of symbols in a plurality of adjacent columns of symbol display positions, each column corresponding to one of the plurality of reel strips, each symbol display position containing one of the selected plurality of symbols, each symbol display position displaying only one symbol;

divide the symbol display positions in each of the plurality of columns into a first subset of symbol display positions and a second subset of symbol display positions;

determine whether an evaluation change condition has been met with respect to a column in the plurality of columns;

perform a first game evaluation based upon the evaluation change condition; and

perform a second game evaluation based upon the evaluation change condition.

9. The system of claim 8 , the game controller further configured to:

perform, in response to a determination that the evaluation change condition is not satisfied, the first game evaluation based on the symbols displayed in the first subset of symbol display positions, and

perform, in response to the determination that the evaluation change condition is not satisfied, the second game evaluation based on the symbols displayed in the second subset of symbol display positions.

10. The system of claim 8 , the game controller further configured to:

perform, in response to a determination that the evaluation change condition is satisfied, the first game evaluation based on the symbols displayed in the first subset of symbol display positions and symbols displayed in the second subset of symbol display positions with respect to which the evaluation change condition is satisfied, and

perform, in response to a determination that the evaluation change condition is satisfied, the second game evaluation based on symbols displayed in the second subset of symbol display positions and symbols displayed in the first subset of symbol display positions with respect to which the evaluation change condition is satisfied.

11. The system of claim 8 , the game controller further configured to update a meter stored in the memory based on the first game evaluation and the second game evaluation.

12. The system of claim 8 , wherein the first subset comprises a number of symbol display positions that is equal to a number of symbol display positions comprising the second subset.

13. The system of claim 8 , wherein each part of each column has a same number of symbol display positions.

14. The system of claim 8 , the game controller further configured to display a barrier separating the first subset from the second subset.

15. An article of manufacture including a non-transitory, tangible, computer readable storage medium having instructions stored thereon that, in response to execution by a computer-based system configured for electronic gaming, cause the computer-based system to perform operations comprising:

selecting, by the computer-based system, a plurality symbols from a plurality of reel strips stored in the memory;

displaying, by the computer-based system and on the display, the selected plurality of symbols in a plurality of adjacent columns of symbol display positions, each column corresponding to one of the plurality of reel strips, each symbol display position containing one of the selected plurality of symbols, each symbol display position displaying only one symbol;

dividing, by the computer-based system, the symbol display positions in each of the plurality of columns into a first subset of symbol display positions and a second subset of symbol display positions;
