In this level, players are typically constrained by a tight budget and are only given to span a gap. The core challenge lies in creating a structure that can support a heavy vehicle while managing extreme stress levels that often lead to the bridge collapsing after the vehicle crosses. Common Strategies for Success
: The goal is usually to build a bridge that allows a specific type of vehicle or object to cross from one side to the other without collapsing. poly bridge 4-9
A common failure in Level 4-9 is the "spring" effect. If you build a long, steep ramp made of jointed wood, the joints act like hinges. When the car hits the incline, the bridge bounces, the joints separate, and the structure collapses. In this level, players are typically constrained by
