Poly Bridge

Poly Bridge is a single-player physics-based puzzle and construction game. Players take on the role of a bridge engineer, tasked with designing and building functional structures across rivers, valleys, and other gaps to allow vehicles to cross safely. There is no narrative context beyond the engineering challenges, with the focus placed entirely on puzzle-solving and experimentation through increasingly complex levels.

Gameplay centers on constructing bridges using a limited budget and a set of materials such as wood, steel, cables, and hydraulic components. Each material has different properties and costs, requiring the player to balance efficiency, durability, and affordability. Bridges must withstand the weight and movement of cars, trucks, and other vehicles, with simulations testing whether designs succeed or collapse under stress. Levels gradually introduce new elements such as drawbridges, moving parts, or multiple stages where the bridge must adapt to different vehicle types in sequence.
