Scrap Cascade

Turn junk into a chain reaction.

Build a little factory that makes every piece count. Arrange machines and conveyor belts, press Run, and watch scrap become goods. Then use what you learned to make the next shift better.

Each run spans five contracts; new seeds change your card offers and later challenges.

Put your waste to work

Shredders and Smelters leave Dust and Slag behind. Let them pile up and your line can jam. Feed them into a Kiln to make Glass, or reclaim them as Scrap and send it back through the factory. Keep your Kilns and Salvagers working to charge the Cascade bonus and make deliveries worth more.

Build around your next choice

Draft machines and upgrades between shifts. Speed up a bottleneck, open a second line, or specialize in Glass and recycling. Combine Gears and Glass into valuable Gadgets—but make room for both supply lines to meet.

Plan between timed production shifts. Rotate parts, redirect outputs, and undo your planning edits while you work out a better route.

Grow, adapt, and earn the final contract

Your bench expands as you progress through five contracts. Later, changing prices, blocked spaces, and closed shipping lanes ask you to rethink a working layout. Preview the next challenge before choosing your reward.

Finish with a work order of your choice: ship Glass, reclaim Scrap, or assemble Gadgets. Meet its production goal and the contract's credit target to complete the run.

Five contracts that move from a starter line to a specialized factory.

Nine machine and conveyor part types, eight materials, and cards that change your production choices.
