The moment a run stops surviving and starts becoming a machine that feeds itself.
Run snowballing happens when early advantages compound into faster clears, safer fights, richer shops, or stronger reward access. It is thrilling, but if too reliable it can flatten late-run tension.
Example
Vampire Survivors weapon evolutions, Balatro Joker engines, and The Binding of Isaac item combos can all turn a shaky start into unstoppable momentum.
Why it matters
Snowballing matters because it is one of the genre's biggest pleasures and one of its biggest balance problems.
