Game Review

Atlantean Treasures Mega Moolah Slot

Any slot enthusiast will know that the words ‘Mega Moolah’ means the money in the slot industry. The classic Mega Moolah game still holds the world record for the highest winning payout in online slot history; a prize of a whopping €17,879,645.12 at the time of this review.

Atlantean Treasures Mega Moolah by Microgaming is the latest concept in the progressive jackpot series and boasts some of the finest sounds and visuals of the bunch. Produced in partnership with Neon Valley Studios, this game offers an in-game top prize of 500x your bet and a Mega Jackpot reward that pays out no less than €1 million.

The underwater-themed game offers an exciting base game where Expanded Sticky Mermaid Wilds and Re-spins can bolster your bankroll until you can manage to trigger the Jackpot Wheel, where you stand a chance at winning one of four progressive jackpots.

Theme, Soundtrack and Symbols

The Lost City of Atlantis hosts this game and promises extraordinary rewards if you are lucky to collect enough pearls. The transparent reels sit to the side of the screen, and the four progressive jackpots dominate the left.

In the background, you can catch a glimpse of some city ruins which now lie under the waves. The graphics are well designed and provided a high definition visual experience.

An up-tempo tune keeps you engaged as you roll the reels in anticipation of matching combinations. The reel symbols all bolster the game theme well. These include a mix of classic slot symbols and underwater themed icons. Symbols include Bars, Blue Sevens, Pink Fish, Purple Fish, Seahorses, Seaweed, and a Starfish.

There is one special icon in the game. The Mermaid Wild has the two-fold power of expanding on the middle three reels when she lands there and substitutes for all standard game symbols in hopes of creating combo wins.

Game Mechanics

The under-the-sea adventure plays out over 5 reels and only 10 paylines for a total bet of between €0.10 and €200. With the promise of nothing less than €1 million as a jackpot haul, this game provides the perfect playground for high rollers.

The medium variance of the game positions it well for payouts, it’s just a pity that the RTP is so low at only 92.08%. Having said this, it is still 4% higher than the original Mega Moolah game which has turned many players into instant millionaires already.

Land combos of three or more matching symbols from left to the right on the reels to start boosting your bankroll, with in-game prizes of up to 500x bet up for grabs outside of the progressive jackpot. This is a bit lower than the previous Mega Moolah game though.

Special Features

Unfortunately, the game does not have a bonus spin round, which it could have benefitted from, as the base game can feel tedious at times. Thankfully, the appearance of Wilds on any of the middle three reels will muster a bit of excitement.

Wild Re-Spins

When a Mermaid lands on reel two, three, or four, it will expand to cover the entire reel, lock in place, and cause the rest of the reels to re-spin for another chance at landing wins. Should you land more Wilds, the process will repeat. You can only land three Wilds on the reels at most, which means that you could trigger up to three re-spins in a row.

Jackpot Wheel

To stand a chance at winning one of the jackpot prizes in the game, you will need to trigger the Jackpot Wheel. To do this, you will need to collect as many pearls from the game (land above the reels on random spins) as possible. It is not certain how many pearls will trigger the Jackpot Wheel, but it is understood that your bet level has a lot to do with its activation.

Once you trigger the wheel, you will get to spin it and walk away with one of the jackpot prizes. The Mini, Minor, Major, and Mega jackpots are continually progressing in value as players bet on the game throughout the network of Mega Moolah casinos. The seeding for the jackpots is as follows:

  • Mini Jackpot: €10.
  • Minor Jackpot: €100.
  • Major Jackpot: €10,000.
  • Mega Jackpot: €1 Million.

Play ‘On The Go’

Atlantean Treasures Mega Moolah is available on Microgaming’s Quickfire platform, meaning that you have access to the content from both your desktop and mobile devices without the need for additional software downloads. Instead, the game can be played directly from your browser in either landscape or portrait view with easy to use controls for ‘touch’ play.

CasinoWow Game Verdict

If playing for a high progressive jackpot is your desire, then Microgaming’s Atlantean Treasures Mega Moolah is the answer for you despite the low RTP. You will need to wade through a rather uneventful base game to get there but landing the Mega Jackpot can change your life in an instant. If the lack of a Free Spin round puts you off, you can revert to the old Mega Moolah classic instead.
