When the feature game is triggered, the configurable symbols are held in place on the display and the player is provided with more spins during the feature game in which to collect additional configurable symbols. Any additional configurable symbols are retained on the display during subsequent spins until the feature game is completed. The configurable symbols include mystery symbols whose value is not determined until the mystery symbol is displayed. A first valuation game, such as a wheel spin, is used to determine the value for the mystery symbols. At the end of the feature game, the player is awarded a prize based on the values carried by the configurable symbols. A second valuation game, such as a wheel spin, is used to provide an enhanced award if the player collects a determined number of configurable symbols during the feature game."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Hold and spin feature game with mystery symbols","description":"A gaming machine provides a base game from which a feature game is triggered when a determined number of configurable symbols are displayed in a base game outcome.
