A Bumper rebounds products and can be used to redirect a factory route, contribute to value or chain behavior shown in gameplay, and serve as one movable object in the 200 kg puzzle. Fans can drive products into the Bumper, but the combined force may throw them out of the intended path. Exact rebound force, value gain, and the community estimate of about 5 kg are not official fixed facts.
Use the Bumper to change direction
Place the Bumper where an incoming product can strike it cleanly and rebound toward a visible target. Begin with a low-speed manual test so that the outgoing angle can be observed without products disappearing across the room. Adjust the panel walls around the rebound before adding stronger airflow.
Contain fan-powered rebounds
Accepted gameplay shows fans and bumpers working together, and also shows products being launched too far. Add side walls or a receiving tunnel, then increase force gradually rather than pointing a strong fan at an open Bumper. A successful design captures varied product angles, not just the first perfectly centered test item.
Treat value behavior as route-dependent
Gameplay demonstrates a value or chain benefit associated with Bumper contact, but the accepted sources do not establish one fixed multiplier. Use the current on-screen value change as evidence for your build and compare it with the extra time or jam risk created by the rebound. A longer path is not automatically better if products regularly miss the Maw or next machine.
Use it as one option for the 200 kg puzzle
Guide and community material mention bumpers among the movable objects that can add mass to the 0/200 kg platform. That makes the tool a possible part of the pile, not a guaranteed exact-weight solution. Watch the platform reading and combine several stable heavy objects instead of relying on the unverified community estimate for one Bumper.
Diagnose inconsistent physics
If the same incoming product rebounds differently, check whether it strikes the same part of the Bumper and whether another item changes the collision. Clear the area, test one product, and inspect the receiving panels before changing multiple tools. The accepted evidence supports the mechanic, while precise force and direction remain sensitive to layout and physics state.
