20000 Leagues Under the Sea is an underwater-themed slot developed by KA Gaming, drawing inspiration from Jules Verne’s classic novel. The game features a steampunk aesthetic, blending Victorian-era submarine technology with deep-sea exploration. Its layout includes a WILD symbol that substitutes for all symbols except SCATTER. The base game pays left to right on active paylines, with only the highest win paid per line. A notable feature is the free spins bonus, triggered by 3 or more SCATTER symbols, awarding 15 to 35 free spins. During free spins, symbols pay both left to right and right to left, increasing win potential. The game also includes a 3x multiplier for all 5-of-a-kind wins, adding to its appeal for players seeking substantial payouts.
