Volcano Goddess Slot by Pragmatic Play

Three colors of scatter, three different behaviors. Black scatters stick with their face value (0.1x to 1,000x). Gold scatters copy the combined value of every black scatter that triggered the round. Green scatters copy the total value of everything on screen - including other greens that already resolved. They process left-to-right, top-to-bottom, so when two greens land on the same respin, the second one copies the first green's already-inflated number. That compounding is how a 243-ways game reaches a 20,000x ceiling.

Six or more scatters give you a choice. Respins start with 6 on the counter, reset on each new scatter, and greens randomly add +1 to the count. The strategy (if you call luck a strategy) is greens landing late, after hundreds of x in black and gold values have accumulated for them to copy. Free spins work differently - 8 spins where the total value of your triggering scatters becomes the "Pay It Again" amount. Every gold scatter during the round pays that amount again while also acting as a wild. Retrigger with 3+ scatters for another 3 spins. At 100x bet, the buy option skips both features and goes straight to the jackpot pick game instead, where you pick from 12 items trying to match three of the same tier across Mini (100x), Minor (225x), Major (1,000x), or Grand (5,000x).

Fill all 15 grid positions with scatters during respins and the Grand jackpot stacks on top of whatever values are already sitting there. The visual presentation - a volcanic island backdrop with a Goddess figure and Eagle high-pays above standard card royals - looks about five years behind Pragmatic's current output. But the mythology-themed dressing is beside the point. The scatter value math underneath, particularly that green-copies-green chain, is doing something most hold-and-win variants don't attempt.
