Extra Class is an engaging idle-management game designed for Android users, where players take on the role of a manager of a multi-story tutoring center. The game allows you to build and optimize classrooms on each floor, hire teachers-managers, and upgrade equipment to maximize revenue. Each floor represents a different subject and has a corresponding level, while elevator doors facilitate quick student movement between classes. The interface displays earnings per second alongside cash and diamond balances, making it easy to track progress.

Players can delve into the core mechanics by clicking on each floor to access detailed panels that show various metrics, including lesson understanding speed and student capacity. Upgrades can be executed in increments or maximized for efficiency, and hiring managers automates processes, reducing upgrade costs temporarily. The game emphasizes long-term strategy, encouraging players to prioritize upgrades that enhance throughput and profitability, ensuring an entertaining and satisfying management experience.
