Poly Bridge

Poly Bridge, sometimes known as Poly Bridge 1 or simply the Dry Cactus bridge builder, puts your engineering skills to the test. It’s a physics-based puzzle game where you design bridges to help vehicles cross rivers and gaps. Sounds straightforward? Think again. You’ll juggle budgets, materials, and angles—and watch as your creations either survive or spectacularly fail. Need a challenge? You got it.

What’s the game about?

At its core, Poly Bridge is about creativity and problem-solving. You get given a map segment, some materials like wood, steel, and cables, plus a budget. Your job: build a bridge that can handle the load. Cars, trucks, even dump trucks roll across in each level, testing your work. Sometimes your bridge holds up, sometimes it doesn’t—and seeing it break can be oddly satisfying.

Key features

• Over 100 levels with increasing difficulty
• Sandbox mode for free-building with unlimited resources
• Simple but effective construction tools
• Realistic physics engine to simulate stresses and loads
• Steam Workshop support to share and download bridges

Lesson learned: always carry a spare bridge design or two.

Gameplay and mechanics

The early puzzles are surprisingly chill—but don’t get comfortable. Later stages force you to balance cost with stability, designing complex structures like suspension bridges or drawbridges. If you’re into tinkering or once doodled bridge ideas in class, this will click. If you’re lucky, your solution will let vehicles slide across without a splash.

More than just puzzles

Poly Bridge isn’t about beating a clock or scoring points. It’s about the “aha” moments when your bridge stands tall and the humor in watching a failed attempt crash into the water. The sandbox mode is where it gets interesting—you can build whatever you want without limits. Ever wanted a bridge made of spaghetti? Now’s your chance (well, sort of).

Why give Poly Bridge a try?

Do you like puzzles that make you *think*? Want to mess around with physics and engineering without a boring textbook? Poly Bridge offers that casual, satisfying vibe. It’s a smart mix of challenge and chill, perfect for short bursts or longer sessions. Just don’t be surprised if you end up rebuilding the same level a few times. Hey, engineering requires patience.
