Claim 10:
11. A method for operating a slot type wagering game, comprising:
determining, by a processor calling a random number generator function a first time, a first set of symbols chosen from a first non-expanding reel;
determining, by the processor calling the random number generator function a second time, a second set of symbols chosen from an expanding reel;
determining, by the processor calling the random number generator a third time, a third set of symbols chosen from a second non-expanding reel;
determining, by the processor, if any of the second set of symbols is a wild symbol;
displaying, on a display of an electronic gaming device, the first set of symbols in a first column and a second column of a playing field;
displaying, on the display of the electronic gaming device, the second set of symbols in a third column of the playing field;
displaying, on the display of the electronic gaming device, the third set of symbols in a fourth column and a fifth column of the playing field, the third column being positioned between either the first and second column or the fourth and fifth column;
determining, by the processor, if any of the second set of symbols is a wild symbol;
in the event the processor determines any of the second set of symbols is a wild symbol, expanding the wild symbol to occupy all positions of the third column, thereby removing at least one symbol that has a higher value than another symbol on the first non-expanding reel or the second non-expanding reel from the third column; and
determining if a combination of the first set of symbols, second set of symbols, and third set of symbols corresponds to a payout.
