Bridge Genius: Setu Builders

Build real-physics bridges, railways and signals across India, and earn your building money by learning.

Ten engineering levels: a creek crossing, a timber railway incline, a deep canyon cantilever, a freight mountain pass, a harbour switchyard, city traffic, a gale-force gorge, an earthquake fault viaduct, an industrial freight corridor and a continental megastructure. Every beam is checked with real truss and beam physics, so a weak design sags and breaks. The BridgeWorks Academy has 7,200 multiple-choice questions for Classes 1 to 12 in physics, chemistry, maths, biology, finance and commercials, plus 200 bridge-skills questions, all in English and Bengali; correct answers earn Civil Grants that pay for your bridges, and you can give grants to Donation Camps that build for the nation. Works with mouse and keyboard, and on a phone or tablet.
