The wild symbol (the Emperor) is key in this game. Even in the base game, it applies a random multiplier to any win it's part of (2x, 3x, 5x, 8x, 18x, 38x, or 88x). Hitting a five-of-a-kind with a high-paying symbol and an 88x wild is the game's jackpot. The full paytable is shown at https://lucky88slots.com/
