Poly Bridge is a creative bridge construction simulation game developed by Dry Cactus. The core gameplay of the game is to let players design and build various bridges to ensure that vehicles can pass safely. Its unique physics engine and open construction system provide players with rich game experience and challenges. The following will introduce the game content and gameplay of Poly Bridge in detail. Poly Bridge puts players in the role of a virtual bridge designer, whose task is to build bridges so that vehicles can pass smoothly through different terrains and obstacles. The level design in the game is very creative, from simple straight bridges to complex suspension bridges, the challenges are diverse and interesting. Each level requires players to solve various bridge construction problems through reasonable design under limited budget and resource conditions. The game adopts a unique polygonal style, and the picture is simple and interesting. Although the graphics seem simple, the physical simulation in the game is very detailed, and the construction and operation of each bridge are affected by real physical laws. This design makes the game visually both easy to accept and challenging. Gameplay Operation The basic operation of the game is very intuitive. Players need to build bridges by simply dragging and clicking. At the beginning of the level, players will see an area where a bridge is to be built and vehicles that need to pass through the bridge. Players can choose from different building materials, such as planks, steel, and ropes, to design bridges based on the terrain and budget. Players can use a variety of building elements in the toolbox to create bridges, such as straight segments, curved segments, support structures, and more. The design of a bridge must not only consider aesthetics, but also ensure that its structure is stable and can bear the weight of vehicles. Players can test the bridge after the design is completed to see how it performs when vehicles pass through. If the bridge cannot support vehicles or has structural problems, players need to adjust the design until the bridge can pass smoothly. One of the core features of "Poly Bridge" is its detailed physics simulation. The design of each bridge needs to take into account actual physical mechanics, including gravity, elasticity, and friction. The physics engine in the game can simulate the bending, stretching, and compression of the bridge, which means that players need to have a certain understanding of the bridge's load-bearing capacity. For example, when players design a suspension bridge, they must take into account the tension of the cables and the support of the bridge deck. If the bridge is not designed properly, the cables may break and the bridge deck may sink, which will make it impossible for vehicles to pass safely. Therefore, players need to constantly test and adjust the design to ensure the stability of the bridge. Each level has a certain budget limit, and players need to complete the construction of the bridge within the specified budget. This requires players to not only consider the functionality of the bridge when designing, but also to allocate resources reasonably. Different materials and construction elements in the game have different costs, and players need to choose the right materials according to the budget. For example, although the use of steel materials can increase the strength of the bridge, it will also greatly increase the construction cost. On the contrary, although the use of wooden boards is less expensive, it may not be able to withstand a large weight. Players need to make a trade-off between budget and materials to design a bridge that is both economical and sturdy. "Poly Bridge" encourages players to be creative and try different bridge design and construction methods. The level designs in the game are varied, from simple straight bridges to complex suspension bridges, floating bridges, cable-stayed bridges, etc., with rich challenges. Each level has different terrain and requirements, requiring players to design and adjust according to specific circumstances. The game also provides multiple modes and challenges, such as time challenges and high-score challenges, which further increase the fun and difficulty of the game. Players can get rewards by completing these challenges, unlock more building materials and design tools, and improve the playability of the game.
