TRUSSFALL: Bridge Builder

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)
• 100% on-device data — zero tracking, zero 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 analytics. No third-party SDKs. No data collection. Your progress lives on your device. Always.

Built by a single developer who couldn't find the engineering puzzle game he wanted to play.
