**Source:** [Rules in Game Server](https://tripledotstudios.atlassian.net/wiki/spaces/KB/pages/2668494860/Rules+in+Game+Server) Rules are a critical component for defining and applying User Groups across different configurations. Here's a comprehensive breakdown of how rules work: ### Basic Rule Operators Rules use two primary logical operators: | Operator | Behavior | |----------|----------| | **AND** | Users must match **ALL** added rules to receive the entity | | **OR** | Users must match **AT LEAST ONE** rule to receive the entity | ### Rule Configuration Features 1. **Multiple Rules**: - You can add multiple rules within a section - Use the **[green + button]** to add additional values to certain rules 2. **Sections and Nesting**: - Supports up to 3 levels of rule nesting - Different colors help distinguish nested rule sections - Can combine sections using AND/OR operators  ### Practical Example Consider targeting users with the following complex criteria: - From France OR UK - AND Game version equal to 2.7.0 - AND Installed the app 15 days ago or more  ### Advanced Rule Management #### Sections - Allow nested rule combinations - Help create more precise user targeting - Can convert existing rules into sections #### Named Rule Groups - Save and reuse rule sets across different features - Simplify configuration by creating standardized rule templates ### Priority and Matching When applying User Groups: 1. Rules are evaluated from top to bottom 2. Sections with higher priority (top of the list) are checked first 3. Users must match ALL rules within a section (when using AND) 4. Users can match ANY rule within a section (when using OR) ### Best Practices - Use sections to create complex, multi-level targeting rules - Leverage AND/OR operators for nuanced user segmentation - Keep rules clear and specific - Use Named Rule Groups for recurring rule configurations ### Validation Constraints - Maximum of 3 levels of rule nesting - Rules must have at least one condition - Priority is determined by the order of sections/groups By understanding and effectively using rules, you can create highly targeted and dynamic User Groups across different configuration settings.
