"When you use our Services, our web servers automatically log your Internet Protocol (IP) address and information about your device, including device identifiers (such as advertising IDs, such as IDFA, IMEI, MAID, and other unique identifiers), device type/model, your device's operating system, and other software including type, version, language, network provider, memory data, and configuration."
The app collects hardware-level identifiers like IMEI and multiple advertising IDs (IDFA, MAID), plus memory data and network provider information, which goes beyond what a game typically needs for core functionality.
