How the Game Plays

Stacks of Pearls transports players to a submerged fantasy realm reminiscent of Atlantis, featuring a serene blue aesthetic filled with sirens, mermen, and ancient shipwrecks. Developed by Lightning Box Games, this slot uses a standard 5x3 grid with 30 fixed paylines. Wins are achieved by landing matching symbols from left to right, with the Siren serving as the highest-paying standard symbol. The core of the gameplay revolves around the Pearl symbols, which act as mystery symbols that can reveal either blank spaces or valuable Wilds to complete winning combinations.

Pearl Bonus Explained

The primary feature of this slot is the Pearl Bonus, which is triggered when full stacks of Pearl symbols land on two or three of the middle reels (2, 3, and 4). Landing two stacks awards 5 respins, while three stacks grant 7 respins. During this mode, the triggering reels are locked in place with Pearl stacks. For every respin, these pearls reveal their contents—either a blank, a standard Wild, or a Wild with a x2 or x3 multiplier. If you land an additional stack during a 5-respin session, the feature retriggers for a total of 7 respins.

Wild Multipliers

The potential for significant wins is concentrated in the multipliers found during the Pearl Bonus. If multiple Wild multipliers contribute to a single win line, their values are multiplied together. For example, three x3 multipliers on a single line create a x27 total boost. Since the pearls appear in stacks, it is possible to fill multiple positions on the center reels with these boosting symbols, significantly increasing the value of standard symbol combinations.
