Poly Bridge 2 is a simulation-puzzle game developed and published by Dry Cactus, with music composed by Adrian Talens. It is the sequel to the critically acclaimed Poly Bridge. It is available worldwide for Linux, macOS, Microsoft Windows, Android, and iOS.

The objective of Poly Bridge 2 is to build a bridge that can take vehicles from place A to place B with materials provided within a limited budget.^[1] In addition to the materials that were already featured in Poly Bridge, a new material, the spring, is introduced.^[2] The game offers eight different worlds which consist of 16 levels each, along with six "challenge worlds" consisting of harder versions of the levels contained in the first six worlds, adding up to a total of 224 levels.^[3] The addition of a feature similar to the Steam Workshop allows players to make and upload their own levels for other players to enjoy. This workshop service is hosted on Dry Cactus's servers, making the game compatible with other launchers such as the Epic Games Store, whereas Poly Bridge's workshop was hosted on the Steam Workshop and was thus restricted to the Steam launcher.

Poly Bridge 2 is developed and published by New Zealand-based video game developer Dry Cactus, with Canadian composer Adrian Talens returning to compose the original soundtrack.^[4] The game was released on Epic Games Store and Steam on 28 May 2020 for Linux, macOS and Microsoft Windows.^[5] It released with four regular worlds and four challenge worlds, with two additional normal worlds and one challenge world added on 2 August 2020.^[6] A mobile version of Poly Bridge 2 was released for iOS on 28 October 2020, and for Android on 30 October.^[7]

A sequel, titled Poly Bridge 3 was released on 30 May 2023.^[8]

Russell Archey of Gaming Nexus rated the game 8.5 out of 10. He felt the game was enjoyable and relaxing, and brought him a lot of happiness every time the bridge he built broke and drivers drove into the water.^[15]

Chris O'Connor of Impulse Gamer gave the game an overall 3.6 stars out of 5. He praised the game for being good fun at a pretty reasonable price, but criticised it for not having enough stages.^[16]

Michael Lafferty of Common Sense Media gave the game 4 stars out of 5.^[17]

John Walker of Rock, Paper, Shotgun commented the game is "far more like an expansion pack than a whole new game", and thought it difficult to enjoy if creating on one's own.^[5]
