BridgeForge

Build bridges on real physics — 112 levels, every one proven solvable.

• Android

A bridge-building puzzle on real physics: pick wood, steel, cable or road, build within budget, and watch the truck cross while every member shows its stress. 112 levels, all proven solvable. Arabic and English. Free.

What it does

• Real structural engineering, not a cartoon: a truss solver with real sections — glulam timber, S355 steel tube, wire rope, composite road deck.
• Members fail the way they do in the field: tension yield, Euler buckling (long struts fold first), deck bending under the wheels, cables that go slack.
• 112 levels in 8 worlds — creek to megastructure — with ship channels, height limits, piers, split-level banks and truck convoys up to 44 tons.
• Every level was proven solvable by the same simulation the game runs, so the budget is always fair; a ghost hint shows a textbook design.
• Live stress colours while the truck crosses: red compression, blue tension, white flash at the breaking point; the peak load is reported after each run.
• Trucks ride on sprung axles over expansion-joint bumps, with a diesel engine note and a distinct sound for every material you place.
• Arabic and English, works offline. Free with an occasional Unity ad between levels (you choose personalised or not).
