Build, run and collect engines in your own pixel-art workshop. Fit parts, tighten bolts, adjust the setup and time the ignition in four scored stages. Keep each finished engine on your shelf, complete Control and Response inspections, or try an untimed Free Run with throttle, load and start/stop controls.
15 ENGINES
Four engines are ready to play. The other eleven can each be permanently unlocked on this device by completing an optional rewarded ad when available. The new designs are an inline three-cylinder, a flat-six and a supercharged V8. A one-time, non-consumable Remove Ads purchase unlocks all 15 engines and removes ads. It is not a subscription.
BUILD AGAIN WITH A GOAL
Follow your next workshop goal, collect inspection stamps and improve your weakest build stage. Assembly, setup and ignition demands now increase across four-, six-, eight- and twelve-cylinder engines.
Compete on the existing online leaderboards through Game Center on iOS or Google Play Games on Android. Each engine has its own board. Existing board IDs and records are preserved; the three new engines have separate boards. Only completed four-stage build scores from 0 to 1000 are submitted, and higher records are kept. Failed score uploads remain queued for retry. Same-rules comparisons are an on-device coaching aid, not a replacement for online rankings. Core gameplay works offline without a separate account. Online rankings require internet and platform sign-in; ads and purchases require internet. Progress is stored on the device. Engine behavior and readings are game approximations, not engineering measurements.
Build 15 pixel engines. Assemble, tune and run your workshop collection.
