Playing Atlantean Treasures Mega Moolah - First Impressions

I sat down with Atlantean Treasures Mega Moolah knowing it was only the second game in the Mega Moolah series, released in February 2020 by Neon Valley Studios. The underwater theme is pleasant enough, and the entry point is low at just 10p per spin. It runs on 5 reels with medium volatility, so I expected a fairly balanced session with wins ticking over at a reasonable pace.

What struck me early on is how stripped-back the base game feels compared to other Mega Moolah titles. The max win sits at only 500x your stake, which is the lowest in the entire series. After a couple of hours spinning, the base game payouts felt modest. But the real draw here is obvious - those four progressive jackpots ticking away in the background.

Atlantean Treasures Mega Moolah Symbols and Paytable

The paytable is fairly straightforward. You get the usual mix of lower-value card royals alongside themed symbols tied to the underwater Atlantis setting. Higher-paying icons include sea creatures and treasure-related imagery. Nothing here will blow your mind visually, but the symbols are clear and easy to read on screen, which I appreciated during longer sessions.

The Wild symbol does its job substituting for other symbols to complete winning combinations. There is no elaborate Wild mechanic like stacking or multiplying, which keeps things simple. Scatter symbols are present but the bonus structure is not as layered as you would find in something like Absolootly Mad Mega Moolah or Immortal Romance Mega Moolah.

How Atlantean Treasures Mega Moolah Bonus Rounds Work

The main event is the Progressive Jackpot Bonus Game, which triggers randomly on any spin regardless of your bet size. When it fires, you spin a jackpot wheel divided into 20 segments across four colours. Each colour corresponds to one of the four jackpots: Mini, Minor, Major, and Mega. You are guaranteed to win one of them once you are in.

The Mega Jackpot seeds at a minimum of two million pounds and pays out an average of around 6.69 million euros roughly every 49 days across the network. During my session I never triggered the wheel, which is expected given the rarity. Higher bets reportedly improve your chances of entering the bonus, but it can land at any stake.

There is no bonus buy feature available on Atlantean Treasures Mega Moolah, which will disappoint players who prefer to skip straight to the action. The lack of a traditional free spins round with multipliers also means the base game carries most of the weight outside of the jackpot trigger.

Atlantean Treasures Mega Moolah RTP and Volatility

The RTP on Atlantean Treasures Mega Moolah is 92.08%, which is low by any standard. However, this is typical for progressive jackpot slots in the Mega Moolah network because around 5.3% of every wager feeds directly into the four jackpot pools. That is how those multi-million pound prizes get built up. If you strip out the jackpot contribution, the effective house edge is more understandable, but your bankroll will still drain faster than on a standard 96% slot.

Volatility is rated medium. In practice, I found base game wins came along often enough to keep me ticking over, but nothing substantial landed without the jackpot wheel. At a pound per spin, you can expect roughly 1,263 spins from a hundred quid on average, which works out to about an hour of play. That is noticeably shorter than higher-RTP games.

Is Atlantean Treasures Mega Moolah Worth Playing?

If you are chasing life-changing money, Atlantean Treasures Mega Moolah gives you access to the same jackpot network that has paid out over 600 million euros since 2006 and produced individual wins north of 19 million euros. The 10p minimum stake makes it one of the cheapest entry points into the Mega Moolah progressive. For jackpot hunters on a budget, that is genuinely appealing.

But if you want engaging base game mechanics, high max wins, or bonus buys, this is not the slot for you. The 500x cap outside the jackpots is the weakest in the series, and the gameplay itself is bare bones. I would recommend Immortal Romance Mega Moolah or Thunderstruck 2 Mega Moolah if you want richer features alongside the same four progressive pots. Atlantean Treasures Mega Moolah is purely a jackpot play - nothing more, nothing less.
