Poly Bridge 3
Kids design bridges from wood, steel, rope and hydraulics, then send cars and trucks across to see if they hold.
Poly Bridge 3 is a bridge-building puzzle game with a strong engineering flavor. Every level shows a gap, a road and some vehicles waiting to cross. Kids lay down beams of wood, steel, rope and cable, add springs and hydraulic pieces, then hit play and send the traffic over. Strained spots glow red, and a weak design sags, snaps and tips cars into the water – which appears to be half the fun. Across more than 150 levels the tasks expand to drawbridges, jumps and moving parts. A sandbox mode removes the limits entirely, and a gallery shows how other players solved the same puzzle. It seems aimed at older kids who enjoy testing an idea and rebuilding; younger ones may find the later puzzles demanding, though the crashes are fun at any age.
