receiving, during the spinning, an add gesture associated with the first player-selectable symbol, the add gesture is configured to represent a request by the player for addition of the first player-selectable symbol to the matrix;

adding the first player-selectable symbol to a first player-populated symbol position of the plurality of player-populated symbol positions in response to the add gesture;

displaying, on the display, a second player-selectable symbol of the sequence of player-selectable symbols in the display area;

receiving, during the spinning, a discard gesture associated with the second player-selectable symbol, the discard gesture is configured to represent a request by the player for exclusion of the second player-selectable symbol from the matrix; and

discarding the second player-selectable symbol without adding the second player-selectable symbol to the matrix,

simulating stopping each reel of the plurality of reels, the stopping revealing symbols of the plurality of reels within the matrix, the first player-selectable symbol overlaying a reel symbol at the first player-populated symbol positions; and

evaluating the symbols displayed within the matrix to determine a game outcome.

7. The method of claim 6 , wherein the plurality of player-populated symbol positions includes one of a row of symbol positions and a column of symbol positions within the matrix of symbol positions.

8. The method of claim 6 , further comprising adding each of the selected plurality of player-selectable symbols to a corresponding symbol position of the plurality of symbol positions from left to right.

9. The method of claim 6 , wherein adding the first player-selectable symbol to the first player-populated symbol position further includes determining the first player-populated symbol position as being the left-most empty player-populated symbol position within the matrix of symbol positions.

10. The method of claim 9 , wherein the display is a touch-screen display, and wherein the add gesture is one of a right swipe and a left swipe on the touch-screen, and wherein a discard gesture associated with discarding the displayed player-selectable symbol is the other of the right swipe and the left swipe on the touch-screen.

11. A non-transitory computer-readable storage medium having computer-executable instructions embodied thereon, which when executed by a game controller of an electronic gaming machine, cause the game controller to at least:

display, on a display, a plurality of reels, wherein each reel includes a plurality of symbol positions, wherein each symbol position is configured to include an associated symbol, wherein each reel is adjacent at least one other reel to form a matrix of symbol positions;

simulate spinning the plurality of reels;
