Extra Class

Extra Class is an idle-management game where you run a multi-story tutoring center. Build and optimize classrooms on each floor, manage elevator flow, upgrade equipment, and hire junior or senior managers to automate upgrades and reduce costs. Track cash/second and diamond balances as you expand capacity, student throughput, and lesson comprehension speed.

Design a long-term upgrade strategy: prioritize floors with high understanding speed and transport capacity, sequence elevators and high-ROI layers, then assign managers for hot zones. The loop of clicking, upgrading x1/x10/x50/Max, and automating creates a satisfying balance of short-term gains and strategic optimization for passive income growth.
