Twenty Thousand Leagues Under the Sea is basically what happens when a guy gets kidnapped by an emo submarine captain with a flair for the dramatic. Captain Nemo, the original ocean goth, sulks around his fancy fish tank of doom (a.k.a. the Nautilus) while monologuing about the evils of mankind. Meanwhile, poor Professor Aronnax and his pals are just trying to figure out if they’re prisoners or unexpected guests at the world’s weirdest Airbnb.

With its wild setting and even wilder characters, Twenty Thousand Leagues Under the Sea is practically begging for a slot remake. AvatarUX seems to agree, as evidenced by its brand-new Depths of Fortune slot.

Welcome to the Nautilus!

The Depths of Fortune slot features up to 16,807 ways spread across five reels. Betting on the slot starts at just $0.10, with a maximum betting limit of $10. If you’re betting at that upper level, you stand to win up to $200,000, thanks to the massive 20,000x maximum multiplier. The slot has low to medium volatility, meaning wins are more frequent but smaller compared to high-volatility games. The RTP is 96.05%.

The Loaded Reel sits next to the main reels, with its top cell acting as the Trigger Zone. As the reels spin or cascade, reward symbols, and blank spaces move from bottom to top on the Loaded Reel. If a reward symbol lands in the Trigger Zone, it activates. In the base game, rewards include expanding the Trigger Zone one position downward, expanding all reels up to three positions upward, applying a multiplier to the current win, randomly upgrading up to five low-pay symbols to high-pay symbols, and adding wilds or colossal wilds to the reels.

Landing at least five Coin symbols on the reels triggers the Hold & Win feature. This round is played on a grid where only blanks, Coins, and Loaded Reel rewards can land. Coins cascade down to the lowest available position and remain in place, carrying values between 1 and 100, while Colossal Coins hold values ranging from 500 to 5,000. The round starts with three spins, resetting whenever a new Coin lands. The Loaded Reel remains active, dropping new rewards and shifting upward with each cascade. Additional rewards in the bonus round include standard and Colossal Coins, Coin Upgrades that boost the value of visible Coins, Extra Lives adding up to three extra spins, a Collect symbol that gathers all Coins on the screen, and a Collect and Multiply symbol that gathers all Coins and applies a multiplier. The Grid Expansion and Trigger Zone Expansion rewards from the base game are also available here.

The Xpress section allows direct access to different game modes. The Fully Loaded mode costs 5x the bet and ensures that every spin features no blanks on the Loaded Reel. The Bonus feature costs 60x the bet and starts with five Coins on a 5×4 grid. Bonus Plus costs 120x the bet and begins with six Coins on a 5×5 grid. Bonus Premium costs 240x the bet and starts with seven Coins on a 5×6 grid, while Bonus Max requires a 500x bet and starts with eight Coins on a 5×7 grid.

Is the Depths of Fortune slot out of its depth?

For a long time, finding an AvatarUX slot that didn’t revolve around PopWins felt like spotting a deep-sea creature—rare and unexpected. But lately, the studio has been more than happy to step outside its signature mechanic, and The Depths of Fortune is another example of that shift.

Visually, the slot impresses with a distinct illustration style that’s both striking and well-executed. On the feature front, the game leans on two key mechanics: the Loaded Reel and the Hold & Win round. Notably, in the base game, the Loaded Reel’s Trigger Zone always starts empty, even when using the Fully Loaded betting option at 5x per spin—something to keep in mind before diving in. Overall, I give the Depths of Fortune slot a ten out of ten.

If you’re looking for a few other non-PopWins slots from AvatarUX, I recommend Big Catch Craze and Donkey and The GOATS.
