Regal Riches and Prosperity Pearl are, mechanically, the same IGT slot released under two different names and themes. Regal Riches uses a medieval-monarchy visual theme, while Prosperity Pearl uses a Chinese theme -- but both run identical five-reel, 30-payline math with the same wild-jackpot structure underneath. Made by Unity, an IGT division, the pair has built a following among slot enthusiasts specifically because of its layered progressive-wild feature, which pairs three separate jackpot meters with the base game's regular paytable.
Regal Riches and Prosperity Pearl are functionally identical slot machines released under IGT's Unity division with different cosmetic dressing. Regal Riches leans into a medieval European monarchy look -- crests, crowns, and castle imagery -- while Prosperity Pearl swaps in Chinese New Year-style iconography built around a treasured pearl. Beyond the reskin, the paytable, feature set, and math model are shared between the two.
Both games use a five-reel, four-row layout with 30 fixed paylines, and support a wide betting range -- from as little as $0.10 up to $500 per spin, depending on the specific cabinet's configuration. Return-to-player is variable by casino, with figures reported anywhere from the high-80% range up to just above 96%, since IGT allows operators to configure the payback percentage within a set range rather than shipping one fixed number.
The feature that sets both games apart is a set of three separate progressive wild-jackpot meters -- commonly described by players as minor, major, and mega tiers -- that build up over time as the game is played and are guaranteed to pay out once they reach a preset ceiling. This "must hit by" style design is what draws sustained player and analyst interest in the Regal Riches/Prosperity Pearl pairing, though the specific meter thresholds and optimal timing for each tier vary by cabinet and aren't published by IGT.
