Build a Bridge! is a complex yet approachable physics-based puzzle game. It tasks the player with creating more and more elaborate bridges across multiple levels. You will have to choose the proper materials, using creativity and logic to stay within required budget and create a strong construction. During the planning phase the game presents itself with a simple, 2D interface. It is there that you select the best materials for your bridge and connect the dots to make the most resilient structure you can. You can approach each level as a complex puzzle, trying to be as efficient as possible and get the best solution. But don't be afraid to experiment too. You can just go crazy and construct something that looks outrageous but still somehow works. There's fun in both of these approaches. When you're done, switch to the 3D mode and watch a car drive through your bridge. Will it hold? Or will you watch a spectacular crash? In addition to the normal mode the game features the easy mode for more relaxed gameplayed, focused on creativity and improvisation. You can also use in-game hint system if things get too hard. With 86 levels to construct you will not run out of things to do quickly. Game features: - Different materials to build from - Wood, Metal, Cables - 86 levels of increasingly difficult puzzles - Varied, detailed environments full of interactive elements - Multiple cars to test out your constructions - Realistic physics engine - Beautiful, stylised art style - Available in 13 languages IGRS rating: 13+

Verdict
The clearest difference is rating: Build a Bridge! at 4.6 against Poly Bridge 3's 3.9. Build a Bridge! also leads on ratings volume (26K vs 126). Poly Bridge 3's advantage is ads (none vs shown) and update cadence (every 4 days vs every 2 months). On price, review sentiment, in-app purchases and monetization model there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Build a Bridge! sells 10 one-off in-app purchases and Poly Bridge 3 sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Build a Bridge! holds the better App Store score, 4.6 against 3.9. That said, the two scores are not equally well evidenced: Build a Bridge! has 26K ratings behind it against 126, so its average is the more settled of the two. Written reviews complicate that: 59% of Build a Bridge!'s written reviews are positive against 67% of Poly Bridge 3's, so the app with the better star average is not the one people write more warmly about.
Build a Bridge! ships an update every 2 months, Poly Bridge 3 every 4 days. The most recent releases landed on September 25, 2026 and September 21, 2026 respectively.
