PG Soft Lucky series: one grid, three reward systems
Unlike a mascot-led sequel chain, PG Soft's Lucky series repeats a 6x5 cascading framework while replacing the character, ways system and bonus behavior in each release. Cats, pigs and Irish symbols provide different skins, but the mechanical arc runs from high ways to sticky wilds and then to pay-anywhere play.

Lucky Neko established the broadest ways setup in 2021 with 32,400 ways, medium volatility and a 5,527x maximum win. Its free spins multiplier and bonus buy put the emphasis on cascade sequences. Lucky Piggy reduced the count to 2,304 ways in 2022 and lowered the ceiling to 3,687x, but added sticky wilds to keep winning positions active across the feature.
Lucky Clover Lady made the decisive risk shift in 2023. It replaced a fixed ways count with pay-anywhere wins, raised volatility to high and extended the maximum to 7,500x. Colossal symbols, locked winning positions, extra free spins and a guaranteed wild during free spins turn it into the most bonus-dependent entry. The shared grid makes the games look related; the treatment of wins after each cascade is what separates them.
