Start on a Search for (Captain) Nemo

We won’t delve into the intricate details of the original story, but it revolves around the thrilling adventures of a Victorian-era captain and his advanced submarine, the Nautilus.

The symbols and design elements exhibit a graphic novel style that complements the theme perfectly. While playing, you’ll encounter playing card symbols resembling pieces of pipework enveloped in an unusual energy, offering smaller payouts. Larger rewards await from various characters, a sea lion, and the charismatic Captain Nemo himself.

Submerge into the Depths

Successful symbols vanish from the reels, creating space for new symbols to drop down. This cascading reels feature can trigger additional wins, leading to more cascades. Each cascade contributes to a Dive Meter located on the left side of the reels. As the Nautilus submerges deeper, lower-value symbols are eliminated from the reels in the following cascade, enhancing the chances of landing high-paying combinations.

Various random modifiers can impact the gameplay of the “20,000 Leagues Under the Sea” online slot. As the depth meter ascends, the likelihood of bubbles bursting through the reels increases, leaving a path of wild symbols behind.

A colossal squid can emerge from the depths, but don’t fret, as its tentacles rearrange symbols to guarantee a win.

Unveil Free Spin Delights

The squid also initiates free spins – five, ten, or 20 – when landing in three, four, or five positions simultaneously. During this round, watch out for unique Nerve Points gained when a blue symbol appears on the far-right reel. These points add extra spins to the round, but a red symbol deducts them.

After every fifth win in the free spins feature of the “20,000 Leagues Under the Sea” online slot, a win multiplier kicks in for the remaining spins. With favorable Nerve Points and sufficient free games, your winnings could be multiplied by up to five times.

As an added bonus, a diver in traditional underwater attire serves as a stacked wild symbol throughout the free spins.

Confront More Colossal Calamari

Giant squids feature in the reels of Microgaming’s “Leagues of Fortune” slot. This game also offers 1,024 ways to win, with Nemo offering the highest payouts. Trigger the free games feature to witness the tentacles of a squid unveiling the number of spins and applicable multipliers.

If you crave for big wins, try your luck with the Eye of the Kraken online slot by Play’n GO. The crew of the Nautilus confronts the legendary beast across a 3×3 symbol grid, where free spins and wild tentacles await the brave.
