Build, upgrade, and automate a circuit of ever-looping machines. Turn small node chains into powerful functions and unlock exponential idle growth that never stops.
Closed Circuit is an incremental automation game where everything you build can be automated, improved, and combined into something smarter. Start with just a few simple nodes. Connect them into a functioning system. Then keep going — deeper, faster, and more efficient than before.
Design a layout that runs itself. Create feedback loops that feed your progress. Turn complex chains into tidy function blocks so your growing machine stays clean and powerful. Step away for a break, and your network will keep pushing forward without you.
The best part? There’s always another layer to uncover, another optimization to chase, and another system waiting to click into place.
