Each gaming reel has a plurality of symbols that are randomly arranged in response to gaming events. A controller is coupled to the gaming reels and configured to randomize, in response to a user input, the plurality of gaming reels so that the gaming reels are in a first configuration. Based on the first configuration of the gaming reels, an arrangement of the symbols that satisfy a predetermined condition is determined. In response to the predetermined condition being satisfied, a subset of the gaming reels is randomized so that the gaming reels are in a second configuration. The subset of gaming reels is randomized independently of any user inputs occurring after the determination of the predetermined condition, and the gaming reels not in the subset of reels are held while the subset of gaming reels is randomized. The apparatus also includes a payout device that determines a payout based at least on the second configuration of the plurality of gaming reels in response to the randomization of the subset of gaming reels."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reel-type gaming activity involving automatic randomization of a subset of reels","description":"A gaming apparatus has a plurality of gaming reels.
