Accurate Physics

We put lots of effort in the physics part of the game and the result is an accurate and consistent simulation, which also gives you access to loads of different building blocks, including hydraulic pistons to create shape-changing and moving bridges, suspension bridges, cable, steel, iron, and more

60+ Levels

Enjoy hours of bridge-building fun with loads of levels to solve, ranging from simple light car bridges to multi-deck draw-bridges and jumps, just to name a few! Levels get increasingly challenging from the engineering aspect and restrictions are also imposed on the resources you can use to build your bridge.


What would an awesome bridge-builder game be without an equally awesome Sandbox? Go wild and create the most complex bridge the world has ever seen, and if you're feeling like it publish your design to the Steam Workshop as a puzzle level for everyone to try and solve!

Download More Levels

Every user submitted level will be available for download free of charge of course, while also allowing the community to interact with each other, challenge friends and send replays. We'll also be featuring the most original and fun bridge designs that players submit, making it easier for you to find the ones that are worth the challenge.

Frequently Asked Questions

Poly Bridge features an easy to use Sandbox mode that allows you to create your own puzzle designs from scratch and upload them online for everyone to try and solve.
Yes. We plan to regularly feature the most prominent and original designs and puzzles, while also allowing you and other players to leave feedback and ratings on user submissions.
The Sandbox allows you to create your own level layout, placing terrain pieces and islands, defining how many vehicles are in the level and the resource limits that apply (if any) among other things (we used the Sandbox to design every level in the game). Once you're happy with the layout you switch to Edit mode, where you build the actual bridge, and then start the simulation to trigger events (cars, ships, hydraulic expansions, etc.) and watch your bridge do its thing. If you wish to submit your level layout as a challenge to a friend and to the rest of the bridge-building community, you must design a successful solution in Edit mode first. Once the simulation runs to its completion with a successful outcome, you will be presented with the option to upload the challenge for others to try and solve. You'll be able to see how many people are playing your design, how many are solving it and what resources they're using, along with other stats.
You can choose to save and share an animated GIF of your bridge at any time with a couple of clicks, pretty cool! And it will also be uploaded to an online gallery of user submissions, super cool!
We'll be offering the game on Early Access, but only in its final polishing stages, as we'd love to give everyone a solid experience while being flexible enough to improve things we might have missed and integrate community feedback before final release.
Yep, we're making sure Poly Bridge runs well on the good old penguin too, you can't make a bridge-builder and not have it run on Linux!
We love seeing what our players are doing with Poly Bridge.
