Factory Planner is a card-based strategy and simulation game developed by Lebleby Games. The core gameplay loop involves strategically placing and connecting Facility, Organization, Engineer, and Resource cards to build intricate production chains. Players manage the flow of solid, liquid, and power resources through 90° angle connections, with incorrect links capable of halting the entire system. Assigning engineers to various cards boosts efficiency, unlocks new recipes, or reduces energy consumption, requiring careful planning as assignments take effect after the current production cycle. The game progresses from basic materials like wood and iron to advanced resources such as uranium, enabling the construction of nuclear power facilities.The experience is presented as a sandbox, allowing players to experiment with factory layouts and automation systems at their own pace, free from time limits or enemy pressure. The focus is purely on production and optimization, challenging players to maintain balance in resource flow, storage capacity, and power distribution. An alert system provides real-time monitoring of critical metrics, notifying players of issues like full storage or power failures. Players can craft or upgrade cards to improve capabilities, scaling their operation from a humble workshop into a large industrial hub.
