Circuit Workshop

An order comes in: 60 plates, or 30 modules without a single defect, or the same output on half the budget. You have a small floor, an ore deposit and a delivery dock. The rest is up to you. Place extractors, cutters, assemblers, inspectors and splitters, connect them with belts and press Run. You watch the shift play out: items moving, queues growing on the belts, machines working or waiting. At the end, one line tells you what held you back and points at the right cell: "What held you back: the Cutter at C3, busy 98% of the shift." Rearrange and try again. There is no single right answer. Every contract has been checked by a program: there are always at least two different factories that fill it, and the first obvious idea is not enough. Stars reward matching the best known output and the lowest known cost. • 15 contracts on a gentle ramp; the first one teaches you by playing • Production, quality, space, budget and few-machines contracts • Capacity indicators: queues on belts, how busy each machine was, the bottleneck marked • A daily contract, the same for everyone, with your best result • Statistics, a daily streak and 8 medals; confetti for every contract you fill • Free mode to experiment with no goal • Share codes: send your factory and whoever gets it sees it running • Pause and resume; the game keeps your factory where you left it • Shapes and icons for everything (● ore, ■ plate, ◆ module, ✕ defect), not just colours • Adjustable text size and a reduce-motion option • Plays offline, no account, no sign-up • Free, with ads and no purchases. No contract depends on watching ads In English, Portuguese, Spanish, French, Italian and German.
