Checkpoint!
Airport security queue sim where you design layouts to keep passengers calm
Visit yaodub.com ↗What is Checkpoint!?
Checkpoint! is a management simulation game where you design airport security checkpoint layouts using rope barriers, gates, and shops. Autonomous passengers flow through your design, and your goal is to keep them satisfied by managing queue psychology—making lines feel shorter through clever routing rather than reducing actual wait times.
You earn money by serving passengers and lose funds when people walk off or get turned away. The game emphasizes that standing still frustrates travelers more than walking, so strategic layout design is key. The maker built it with Claude Fable in a single context window.
