Progressive Multiplier

A progressive multiplier is a slot multiplier that climbs step by step as a defined condition repeats, rather than being drawn at random for a single spin. The usual triggers are consecutive winning spins, each cascade in a tumbling sequence, every wild collected during free spins, or each new reel added by an expanding engine. The multiplier normally rises one level at a time and resets when the chain breaks or when the feature ends, though some games keep it for the whole round. Because the largest multipliers sit at the end of long chains that occur rarely, this design concentrates a big share of the theoretical return in outcomes most sessions never see. That makes progressive multipliers a strong marker of high volatility and long gaps between meaningful wins.
