About

Model Engine Builder

Features
Read full description

Build an engine, bring it to life and keep it in your own pixel-art workshop. Model Engine Builder combines hands-on assembly challenges with engine inspections and an untimed Free Run. BUILD IN FOUR STAGES Fit the parts, tighten the bolts, adjust the setup and time the ignition. Your four stage scores make a build total from 0 to 1000, with online leaderboards. RUN YOUR OWN ENGINE After building, select your engine in the workshop and try Free Run. Control the throttle and engine load, start or stop the engine, and watch its revs, heat and vibration without a time limit. Control and Response inspections are separate scored tests: pass all their segments to earn shelf stamps. Test results and Free Run do not change your build score. 12 ENGINES, 4 READY TO PLAY Four engines start unlocked, including the inline two-stroke twin. The other eight, including the V12, can each be unlocked on this device by completing an optional rewarded ad when available. A one-time, non-consumable Remove Ads purchase unlocks all 12 engines and removes ads. It is not a subscription. Build and run unlocked engines offline without a separate game account. Ads, purchases and online leaderboards require an internet connection; leaderboards may require platform sign-in. Progress is stored on your device. Engine behavior and displayed readings are game approximations, not real engineering measurements.
