Reward Group Segmentation for Game Engagement

The patent segments the lottery system into multiple reward groups (first reward group, second reward group, etc.), each containing different types of rewards. Instead of a single lottery determining all outcomes, the system divides rewards into categories and uses separate determination processes for each group, allowing players to accumulate achievements across multiple segments and maintain motivation even when individual lotteries are unsuccessful.

The patent implements preliminary action by predetermined setting the reward group information and achievement conditions before the lottery process. The system pre-defines what constitutes an achievement (e.g., gaining a certain number of rewards of specific types) and automatically determines achievements based on lottery results, providing players with clear goals and guaranteed rewards for meeting criteria, thus maintaining motivation.

The patent applies universality by designing the reward determination apparatus to handle multiple reward groups and achievement types through a unified framework. The same basic determination process is reused across different reward groups, with the system universally applying achievement conditions and reward issuance logic regardless of which specific reward group is being evaluated, thereby managing complexity through standardized multi-functional processing.

The patent implements nesting by placing multiple reward groups within a hierarchical structure where the determination apparatus contains sub-components for each reward group, which in turn contain achievement conditions and reward definitions. This nested organization allows the complex system to be managed through layered abstraction, where higher-level control coordinates multiple lower-level reward mechanisms.
