Information about the plurality of items has a data structure in which the plurality of items are linked to have a parent-child relationship. The lottery processing section sets the lottery range so that a child item is included within the lottery range when a parent item has been set to an acquired state or an acquirable state, and changes the set lottery range based on given information."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Game system, server system, processing method, and information storage medium","description":"A game system includes a game processing section that performs a game process, a lottery processing section that sets a lottery range that specifies a range of items among a plurality of items used du","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9844731","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
