Atlantean Treasures Mega Moolah is a striking underwater twist on the iconic Mega Moolah progressive jackpot series that launched in 2020. Developed by Neon Valley Studios exclusively for Microgaming, this game trades the African savannah for submerged ruins and floating sea creatures — but keeps the four guaranteed progressive jackpots firmly intact.

It’s not a sequel to the original Mega Moolah slot in terms of gameplay, but more of a thematic offshoot with fresher visuals and new bonus features. And yes, the elusive mega jackpot still starts at £1 million and can be triggered at random, just like the original.

Atlantean Treasures Mega Moolah Slot Overview

⭐️ Reels / Rows / Paylines: 5 / 3 / 10

⭐️ RTP: 92.08%

⭐️ Volatility: Medium

⭐️ Bet Range: £0.10 – £200

⭐️ Jackpots: Mini, Minor, Major, Mega

⭐️ Top Base Game Win: 500x your stake

⭐️ Mobile-Friendly: Yes – HTML5 optimised

The game uses transparent reels set deep beneath the waves, surrounded by coral and treasure. Symbols include bar icons, lucky 7s, and colourful sea creatures, all floating in air bubbles. The aesthetic is clean, soft, and perfectly suited to mobile play.

Gameplay & Bonus Features

Win Both Ways

Unlike the original, Atlantean Treasures is a win both ways slot — so winning combinations can start from reel 1 or reel 5. This small tweak increases your chances of hitting something decent with every spin.

Expanding Wilds & Re-Spins

The wild symbol — a purple-haired mermaid — only appears on reels 2, 3, and 4. When it lands, it expands to cover the entire reel and triggers a re-spin. If another wild lands during a re-spin, it locks in place and awards another re-spin. You can fill up to 3 wild reels this way, making it easier to hit the game’s top 500x payout.

Progressive Wheel Trigger

The golden pearl symbol is your gateway to the jackpot wheel. When it appears above a regular symbol (not a wild) on reels 2, 3, or 4, the progressive jackpot wheel spins and awards one of the following:

⭐️ Mini Jackpot – starts at £10

⭐️ Minor Jackpot – starts at £100

⭐️ Major Jackpot – starts at £10,000

⭐️ Mega Jackpot – starts at £1,000,000

As with all Mega Moolah progressive games, the progressive jackpot value increases with every spin made across the network — so you could trigger the Mega prize on any spin, regardless of stake.

RTP & Volatility

The 92.08% RTP is higher than the original Mega Moolah slot, but still lower than average due to the progressive jackpot contributions. This version is also medium volatility, offering a smoother ride between features — perfect for players who want something more stable than the base Mega Moolah game.

Our Take on Atlantean Treasures Mega Moolah Slot

Atlantean Treasures Mega Moolah modernises the series with crisper graphics and smoother features while keeping the famous Mega Moolah progressive jackpot at the core. The expanding wilds, re-spins, and dual-direction paylines give it more gameplay variety, and the fresh setting makes it a nice alternative if you’re burnt out on lions and monkeys.

While there’s no free spins bonus, the stacked wild feature makes up for it — and let’s be honest, you’re here for that mega jackpot anyway.

More from the Mega Moolah Series

Atlantean Treasures is just one of several slots linked to the famous Mega Moolah progressive jackpot network. Microgaming (now operating as Games Global) has expanded the series with multiple themed entries — all connected to the same four-tier jackpot system: Mini, Minor, Major, and the life-changing Mega Jackpot.

Each game in the series brings its own style and features, but any spin, on any game, can randomly trigger the Mega Moolah progressive jackpot.

Here are some of the most popular linked titles:

⭐️ Mega Moolah – The original safari-themed jackpot slot, launched in 2006. Still going strong with wild lions, monkey scatters and classic free spins.

⭐️ Absolootly Mad: Mega Moolah – A surreal Alice in Wonderland-style slot with tumbling reels and growing multipliers. Holds the current record for biggest Mega Moolah win.

⭐️ Book of Mega Moolah – Combines the “Book of…” free spins mechanic with jackpot potential. Expanding symbols help boost base wins.

⭐️ Fortunium Gold Mega Moolah – A steampunk-themed entry with Mystery Symbols and enhanced visuals.

⭐️ Juicy Joker Mega Moolah – A classic fruit machine-style option for players who prefer a more traditional slot experience.

⭐️ Mega Moolah The Witch’s Moon – A dark, mystical entry in the series featuring expanding symbols and eerie charm.

No matter which version you choose, every spin contributes to the same jackpot pool, and each slot gives you a shot at the mega jackpot, which always starts at £1 million.

Atlantean Treasures Mega Moolah Slot FAQs

How do I trigger the progressive jackpot in Atlantean Treasures Mega Moolah?

The progressive jackpot is triggered when a golden pearl symbol appears above a symbol on reels 2, 3, or 4. This activates the jackpot wheel, which guarantees one of four jackpots: Mini, Minor, Major, or Mega. The trigger is random and not affected by specific combinations.

Can I win the Mega Moolah jackpot on a small bet?

Yes. Like all games in the Mega Moolah series, the Mega Jackpot can be won on any bet size. Your chances may scale slightly with your wager, but even the minimum stake qualifies for the full prize — including the £1 million+ mega jackpot.

What are the main bonus features in this version?

The key bonus features include:

Expanding Wilds (the mermaid wild fills the reel)

Re-spins when wilds land

A randomly triggered jackpot wheel
There’s no traditional free spins bonus, but the re-spin mechanic adds plenty of action.

Does the game pay both ways?

Yes. Atlantean Treasures Mega Moolah is a win both ways slot, meaning winning combinations can form from left to right and right to left — boosting hit frequency and overall payout potential.

Is this slot mobile-friendly?

Absolutely. It’s built in HTML5, so it plays smoothly on all devices — no downloads needed. Whether you're on iOS, Android, or tablet, the underwater visuals and features are fully optimised for mobile.
