Gaming system

Computer-readable memory having stored thereon instructions for causing one or more processors, when programmed thereby, to perform operations to achieve a given level of volatility while maintaining a target level of return to player (“RTP”) at an electronic gaming device, the operations comprising:

• causing display of a reconfigurable symbol display area on one or more display monitors of the electronic gaming device, the reconfigurable symbol display area having a number of rows and a plurality of columns, each of the plurality of columns having an associated reel, the reconfigurable symbol display area enclosing symbol locations for each of the plurality of columns, wherein, to change volatility, the associated reel for at least one of the plurality of columns is changeable between a wild reel and a non-wild reel for that column between spins of a feature, and wherein, to change volatility, the number of rows is changeable between the spins of the feature;
• for a first spin of the spins of the feature, causing a first symbol array to be displayed in the reconfigurable symbol display area at the symbol locations enclosed by the reconfigurable symbol display area, the first symbol array showing only wild symbols for any of the plurality of columns for which the associated reel has been changed to the wild reel for the first spin;
• causing display of a first indicator of a first outcome for the first spin;
• before a second spin of the spins of the feature, performing a modification to the reconfigurable symbol display area, the modification being based at least in part on state of the reconfigurable symbol display area before the second spin, thereby providing dynamism to the reconfigurable symbol display area and changing volatility for the target level of RTP, wherein the modification includes causing display of a change of the associated reel for one of the plurality of columns between the wild reel and the non-wild reel for that column;
• for the second spin, causing a second symbol array to be displayed in the modified reconfigurable symbol display area at the symbol locations enclosed by the modified reconfigurable symbol display area, the second symbol array showing only wild symbols for any of the plurality of columns for which the associated reel has been changed to the wild reel for the second spin;
• and
• causing display of a second indicator of a second outcome for the second spin.

A method for achieving a given level of volatility while maintaining a target level of return to player (“RTP”) at an electronic gaming device, the method comprising:

• causing display of a reconfigurable symbol display area on one or more display monitors of the electronic gaming device, the reconfigurable symbol display area having a number of rows and a plurality of columns, each of the plurality of columns having an associated reel, the reconfigurable symbol display area enclosing symbol locations for each of the plurality of columns, wherein, to change volatility, the associated reel for at least one of the plurality of columns is changeable between a wild reel and a non-wild reel for that column between spins of a feature, and wherein, to change volatility, the number of rows is changeable between the spins of the feature;
• for a first spin of the spins of the feature, causing a first symbol array to be displayed in the reconfigurable symbol display area at the symbol locations enclosed by the reconfigurable symbol display area, the first symbol array showing only wild symbols for any of the plurality of columns for which the associated reel has been changed to the wild reel for the first spin;
• causing display of a first indicator of a first outcome for the first spin;
• before a second spin of the spins of the feature, performing a modification to the reconfigurable symbol display area, the modification being based at least in part on state of the reconfigurable symbol display area before the second spin, thereby providing dynamism to the reconfigurable symbol display area and changing volatility for the target level of RTP, wherein the modification includes causing display of an addition of a new row for the reconfigurable symbol display area;
• for the second spin, causing a second symbol array to be displayed in the modified reconfigurable symbol display area at the symbol locations enclosed by the modified reconfigurable symbol display area;
• and
• causing display of a second indicator of a second outcome for the second spin.
