Unleash your engineering creativity with Poly Bridge, the acclaimed bridge-building simulator! Experience hours of physics-based puzzle solving with over 100 levels of campaign play. You'll need to build bridges for cars, trucks, and even monster trucks while managing limited budgets and materials like wood, steel, and hydraulics. Will your bridge hold, or will it come crashing down? With a beautiful low-poly art style and a relaxing soundtrack, Poly Bridge is the perfect blend of challenge and fun.

Dinsun Expert Review

Our Expert Score

94/100

Poly Bridge is a masterclass in physics-based puzzle design. On the surface, it’s about getting a vehicle from point A to point B, but beneath that lies a complex and rewarding engineering simulator. The transition from the PC version to mobile is flawless—the touch controls for drawing struts and cables feel even more natural than a mouse.

What sets Poly Bridge apart is the 'failure' loop. Seeing your bridge collapse in a spectacular heap of wood and steel is almost as fun as finally getting it right. The sandbox nature of the game encourages you to be as efficient or as ridiculous as you want. Whether you're building a simple suspension bridge or a multi-level hydraulic drawbridge that launches cars into the air, the satisfaction of that 'Stage Clear' notification is unmatched. It’s a game that respects your intelligence while providing a whimsical, low-poly aesthetic that keeps things lighthearted.

Brilliant Game! Hours of Gameplay!
Wed Jul 19 2017 Rishi S.

This is a really awesome, and challenging game. It's not like one of those games with arbitrary criteria for winning. It gives you very detailed information on objectives and precise visualization of stresses. You can change the camera angles and speed up or slow down gameplay to really get granular with how you solve each design challenge. The graph that shows how your design compares to that of other players is a nice touch. I keep trying different designs just to be more economical. The developer gets extra kudos for making a game free of any up-sells. Worth every cent!

Great but needs some help

I love this game so much. It’s the perfect challenge puzzle game with realistic physics. The challenge of making your bridges work and stay under budget always has me thinking of ways I can do more with less. However my one and only complaint with the game is how heavy it runs the battery down. Just playing for 5-8 minutes knocks off 10% or more of my battery power. It’s been the top consumer of energy on my phone since downloading. It also causes my phone to get very hot as the demand on the phones performance is increased. If there’s an update that could improve the functionality of this games performance impact on my phone I’d give it 6 stars if I could. Until then due to the high impact on battery life my review will remain a 3.

Good game with a couple of severe design flaws
Mon Sep 07 2020 1762chicago

The problem is that you you can contract a hydraulic up to 50% (halving), with the opposite of this being expanding 100% (doubling). The game only allows you to expand a hydraulic 50%, meaning that two identical hydraulics starting in opposite configurations at full range of motion are impossible. This means I have to reengineer a second solution for what should be an identical second bridge in level 2-13 Either there needs to be the ability to expand a hydraulic 100%, or you need to be able to set a hydraulic to start in a different simulated state when the level is run. The first solution would work and be much less invasive a change than adding starting states for hydraulics, but that leads to the second design flaw. In order to create something in a different state, you still have to completely redraw it. There really should be a way to move and rotate groups of joints in order to translate existing designs. The lack of this ability means redrawing constantly. 3 stars because the issues mentioned seriously impede on the fun aspects of gameplay

Great game, sometimes extremely tedious
Sun Oct 20 2019 ben55418

As a player who has unlock the secret world,(every level 3 star other than area 52) I enjoyed the game soo much. The simulation is amazing, all the levels force you to be creative, and it’s overall great fun! Except for some of the levels, the tedious ones. these levels are the types of levels that force you to keep adjusting you’r creation one tiny bit at a time until you’r bridge doesn’t break. So if you want to unlock the secret world you’ll need to invest many hours.

It’s so hard
Wed Jan 16 2019 VanillaNyx

I really like this game, I just wish I had more hints. The game does have a tutorial that you can review as many times as you need. Plus each level tells you the order of events that will take place - that becomes more helpful as you get into the harder levels with multiple cars trying to get different places. But the rest is up to you, so it’s easy to get stuck on level. You might almost have the solution but something is off, so it doesn’t work. I’m stuck right now, I’m sure I will figure it out eventually if I keep trying, but for now I think I’m gonna try to skip the level.

One of the best mobile games
Tue Nov 28 2017 Randomname7464

I have played this game on pc and it was very fun so I was excited to see it came out on mobile. I caught it on sale so it was only $1.99 at the time. A great deal if you ask me. This is definitely the best bridge building game if not one of the best mobile games out there. They did a really good job on making good and simple touch controls which makes the game even more enjoyable. In fact I almost like the controls better than on pc. So much content in the game too. Really enjoy it.

One of my favorite puzzle games!

I’ve watched a couple people play this game before and it looked pretty fun. I’ve only seen people play on computers so I was pleased to see they have mobile versions. You get the same building options and functionality (campaign/sandbox) however you cannot get custom content (at least I haven’t found out how yet if you can.) Love the graphics and challenges they give you, very creative. Definitely worth it!

Great game, touch controls are very frustrating
Mon Dec 23 2019 snoozebar

I’ve played other versions of this game and love it, but the iPhone version is extremely frustrating. The touch controls aren’t programmed well. For example, trying to select the line curve guide to change the curve of the line works maaaaaybe one in four. Instead you’ll just move the screen around. I accidentally hit the wrong material all the time - the selectable area is small. And the selection tool is wonky - it doesn’t select what it should, or it selects unrelated items. I am still having fun with it, but MAN do I want different controls
