Abstract
Methods of playing games of chance and gaming devices and systems comprising a display of a plurality of symbols where at least one symbol may be interchanged with another symbol of the plurality of symbols. After a combination of symbols is randomly generated and the results are displayed to a player, the player may have the opportunity to interchange at least one displayed symbol with another symbol in order to configure a more advantageous symbol arrangement. Interchanging may include transposing, sliding, or moving one or more symbols that are generated by way of a random process. Furthermore, interchanging may include a slide game or wraparound type movement of symbols or trading a symbol for another symbol provided by an exterior source. Additionally, the interchanging opportunity may be limited by way of constraints applied to movement of the symbols, time for interchanging, or other criteria, and may be conditioned on placing an additional or side bet.
