Finally, the world of civil engineering in a mobile game. (Goodbye, RPGs.) Using an allotted number of girders, you have to build rail bridges over valleys and chasms. Get weight distribution and stress points right and the train will pass. Mess up and you'll hear the screams of passengers plunging to their deaths.
WIRED Realistic physics engine keeps things predictable but challenging. Free-build mode has unlimited girders.
TIRED No pinch-to-zoom. More materials options would be nice.
