Concurrent display and interaction between game types on an electronic gaming device

A gaming device comprising:

• a player interface;
• a display system comprising one or more display devices;
• a game controller comprising one or more processors, the game controller executing instructions which cause the game controller to:
• determine a first base game outcome of a first instance of a base game based on a random number generator outcome;
• control the display system to present the first base game outcome in a first window of the one or more display devices;
• and
• in response to the first base game outcome, determine whether a first feature game trigger condition of a feature game exists;
• in response to determining that the first feature game trigger condition exists:
• control the display system to present a first feature game in a second window of the one or more display devices concurrently with presenting the base game in the first window of the one or more display devices;
• determine a second base game outcome of a second instance of the base game;
• determine a first feature game outcome of a first instance of the feature game;
• control the display system to present the second base game outcome in the first window;
• control the display system to present the first feature game outcome in the second window while the second base outcome is presented in the first window;
• determine that a copy symbol condition exists in the second base game outcome;
• identify a set of symbols and their respective symbol locations in the second base game outcome to copy from the base game to the feature game;
• copy the set of symbols to the first feature game in symbol locations of the first feature game corresponding to the respective symbol locations in the second base game outcome;
• determine an updated game outcome for the first instance of the first feature game based on the copied set of symbols, wherein the updated game outcome includes presenting another feature game in another window of the one or more displayed devices;
• and
• control the display system to present the updated game outcome.
