A run ends when the ball contacts lethal red geometry or leaves the playable route in the standard Slope experience. Strategy should therefore create clearance, not rely on grazing the edge of a hazard.
Treat red obstacles as hard failures
Do not plan a line that depends on barely touching a red block. Visual perspective and speed make tiny clearances difficult to judge, and the collision result is not a place to search for extra score.
Edge loss is a geometry problem
Falling often begins before the final edge. A late dodge or long hold can leave the ball on a trajectory with no platform left for recovery. Review the input that created that line rather than only the moment the ball disappeared.
Clearance has two sides
A route needs enough room to pass the current hazard and enough room to recover afterward. Moving as far away as possible from one red block can be just as dangerous if it places the ball against the opposite edge.
Hosted versions may differ at the margins
Different browser builds or ports can vary in visuals and exact collision behavior. Base advice on obvious safe space rather than claiming a precise invisible hitbox measurement that has not been verified for the active client.
Apply Collisions and Run-Ending Hazards in a normal run
Practice this topic as a sequence of observations, not as a demand to force the same steering on every generated track. For Collisions and Run-Ending Hazards, keep the first visible principle in mind: Treat red obstacles as hard failures. Then use edge loss is a geometry problem as the second checkpoint, so the test covers both the initial choice and what follows from it.
On the first attempt, record the baseline: where the line starts to become unstable and which feature is visible at that moment. On the second, apply the cue earlier while using no extra steering. On the third, repeat the same cue and judge the exit line rather than only whether the immediate hazard was cleared.
If the run still breaks down, separate recognition, timing and follow-through. You may see the right route but commit late, or commit correctly and keep steering after the useful movement is finished. Fix the first failing layer rather than treating the entire sequence as one problem.
