Rivet Works is a compact factory optimization game built around one satisfying question: what is slowing your line down right now? Build a production chain, watch materials move from source to sale, spot the bottleneck, then tune the machine that actually matters. Every upgrade changes the flow. Every rebuild turns hard-earned Blueprints into permanent advantages for the next Workshop. WHAT YOU DO • Run a visible multi-stage factory line • Find starved, blocked, and overloaded machines • Upgrade speed, value, capacity, and automation • Trigger Overdrive and chase Perfect Flow • Complete Contracts and Daily objectives • Rebuild for Blueprints and permanent research • Choose Shift Brief directives that reshape the next run • Earn offline production while you are away BUILT FOR SHORT, REPEATABLE RUNS Rivet Works is designed for quick check-ins and longer optimization sessions. The factory keeps its state locally, so your core progress does not depend on creating an account. FAIR OPTIONAL MONETIZATION The Android version may contain limited ads. Rewarded ads are optional. A one-time Remove Ads purchase removes forced/interstitial ads. The one-time Supporter purchase includes Remove Ads plus an in-game Supporter badge. No loot boxes. No gambling. No competitive pay-to-win system. Tune the line. Find the constraint. Rebuild smarter.
