Put your inner engineer to the test in Poly Bridge, the charming, physics-based bridge-building puzzle game—now with fresh levels, new mechanics, and a finely tuned custom physics engine.
Sketch blueprints, pick materials, and iterate until your design carries cars, trucks, and convoys across outrageous gaps. The brand-new Spring material adds flexible, bouncy structures for creative solutions and clutch saves, while deterministic simulation ensures identical results for everyone—perfect for fair competition and replay sharing.
Settle into the vibe with an original Adrian Talens soundtrack featuring 13 new tracks and 18 remastered classics. Draft, test, tweak, and triumph—one satisfying solve at a time.

Gameplay

Each puzzle begins at the drawing board: you lay down road, brace with wood or steel, suspend spans, and now weave in springs to absorb impact or convert vertical forces into helpful rebounds. Hit “simulate” to watch your creation flex and strain in real time; color-coded stress maps expose weak points so you can re-triangulate, re-tension, or re-route load paths within a tight budget. New mechanics introduce trickier vehicle behaviors and multi-phase crossings that demand timed movement, counterweights, or spring-loaded ramps.
Because the physics are deterministic, a design that succeeds on your device will behave the same on your friends’, making leaderboards, challenges, and solution replays genuinely comparable. The loop is pure engineering: hypothesize → build → test → analyze → refine—until your bridge holds and the convoy sails through.
