Cogtender

Cogtender is a slow, satisfying assembly game about building intricate devices with your own hands, one precise step at a time. In front of you sits a piece to work on — a different shape and layout every time — and a set of tools laid out beside it, and your job is simply to put it together, step by careful step. Each build breaks down into small tactile actions that use the whole touchscreen: pick up the right tool and bring it to the right spot, then press and hold to seat a component, tap rapidly to drive in a fastener, drag in a circle to turn a screw, swipe to wipe and polish, or trace a path to route a wire. Tools snap into place when you bring them where they belong, and each step only completes when you perform its action correctly — so the whole thing has a real hands-on rhythm, like actually assembling something rather than just watching it happen. Follow the sequence, feel each piece click into position, and watch a bare shell become a finished device. With a variety of builds, each with its own shape, parts, and order of operations, and a clean interface built around the actions themselves, Cogtender is made to be calm, focused, and quietly addictive. There's no timer breathing down your neck — just you, the tools, and the satisfaction of a job done right. Everything runs on your device: no account, no connection, no ads. Just tools, parts, and the pleasure of building.
