TRUSSFALL vs Engine Simulator

TRUSSFALL is bridge engineering, no shortcuts. Build and stress-test real bridge designs across 99 engineering trials. Place beams, add cables, and triangulate trusses — then send a car, truck or mega-rig across to see if your structure holds. Four materials unlock as you advance: - Wood — cheap, low strength, good for short spans - Steel — your workhorse: strong, stiff, balanced - Cable — tension-only; build suspensions and cable-stays - Reinforced concrete — heaviest, strongest, end-game Build your truss. Run the live load. Watch a vehicle roll across. If your design holds, you earn stars. If your weakest joint snaps under tension, gravity wins. EVERY LEVEL PLAYABLE FROM DAY ONE All 99 trials are free to play. The Lifetime Unlock removes the hint paywall (3 free hints per game), grants unlimited hints, and reveals all engineering-accurate bridge templates. Optional hint packs available too. WHAT'S INSIDE - 99 engineering trials with progressive difficulty - 10 distinct biomes with unique terrain features - 4 materials with realistic structural properties - Warren, K-truss, Pratt, suspension, cable-stay, arch templates - Live load simulation with stress-tested physics - 3 free hints; Lifetime gives unlimited - Family Sharing supported (Lifetime only) - Progress stays on your device — no tracking, no ads, no accounts ENGINEERED FOR THE PATIENT Truss math is computed live. Joints carry real loads. Members have real strength limits. Cables can only pull, never push. These are the same principles a civil engineer uses — and the level designs reward thinking like one. If you've played Bridge Constructor or Poly Bridge and wanted something with more engineering depth, this is for you. PRIVACY-RESPECTING BY DESIGN No third-party SDKs, no ads, no tracking, no accounts. Your progress lives on your device. Anonymous usage statistics (no ID, no location) help us tune the trials, and you can switch them off anytime in Settings. Built by a single developer who couldn't find the engineering puzzle game he wanted to play.

Engine Simulator is a physics-based piston engine sandbox. The sound and motion come from a real rigid body simulation of the crank, pistons, valves, and combustion, not recordings. Start an engine, work the throttle, and tune its fuel and ignition maps in the ECU. Build one from scratch (layout, bore, stroke, cam, firing order) or describe what you want and have it generated on device. Watch it run in 3D, read live power and torque on the dyno, or push it past the limiter until it breaks. Post your engines to the global leaderboard and compare against other builders. Engine Simulator for iOS is an unofficial port. It is not affiliated with, endorsed by, or supported by AngeTheGreat (Ange Yaghi), the creator of the original open source Engine Simulator.
