Game Mechanics and Core Features

The six-reel setup includes a horizontal reel above positions 2-5, adding four extra symbols per spin. Reels 1 and 6 display 2-7 symbols, while middle reels show 2-6. Cascading wins remove successful combinations, dropping new symbols from above—the top reel replenishes from right to left.

Wild horseshoes appear exclusively on the horizontal reel, substituting for everything except scatters. The Super Gem symbol—also top-reel only—transforms all visible gem symbols into a single matching type, including itself. Four or more Pot of Gold scatters trigger 12 free spins with an unlimited multiplier that increases by 1x after each cascade. Additional scatters award five extra spins each.

🎯 Expert Tip: The Super Gem often hits when multiple gem types are visible—maximizing transformation value. Watch for this on dense reel configurations with 7+ gems in view.
