Abstract: Systems and methods for electronic gaming are provided. The systems and methods include performing an RNG pull and memory lookup in a first lookup table to determine and store a minimum number of winning game patterns that a feature game will generate. Initial trigger symbols and additional trigger symbols are determined for display within symbol positions of a feature game symbol matrix. Symbol positions are selected as part of a symbol filling processing stage. After filling of unoccupied symbol positions in the symbol filling processing stage, the filled symbol positions of the feature game symbol matrix are compared to the minimum number of winning game patterns stored in at least one memory device to determine that the minimum number of winning game patterns has been satisfied. A symbol set for the feature game is generated, and the feature game is implemented using the generated feature game symbol set.
