Poly Bridge

Poly Bridge is a bridge-building simulator built around physics-based puzzles. In the Campaign, you solve levels by designing bridges under increasingly difficult engineering challenges and restrictions on the resources you can use. The levels range from simple bridges for light cars to multi-deck drawbridges and jumps.

Campaign and Sandbox

After tackling the Campaign, you can use the Sandbox to design bridges and create puzzles of your own. Build complex structures or experiment with designs that push the game’s mechanics in new directions, then publish your designs online as Workshop puzzle levels for others to solve. You can also download hundreds of additional levels submitted by other players and challenge friends and the Workshop community to complete your puzzles. Original and fun bridge designs are featured to help players find them.

Building tools

The in-game building and level-design tools include:

• Advanced hydraulics
• A multi-phase hydraulics controller for choosing when each hydraulic piston activates
• A node-based event system
• Multiple types of checkpoints
• Copy and paste tools
• Line-tracing tools for drawing arcs or straight lines and filling them with a chosen material

You can also save animated GIFs of your bridges, whether they succeed or fail, locally or to the Poly Bridge Online Gallery, and share them on Twitter, Facebook, Reddit or Tumblr from within the game.
