Atlantean Treasures: Mega Moolah is Microgaming's 2020 attempt to bring their famous progressive jackpot network into an underwater kingdom setting. The idea is straightforward — take the Mega Moolah jackpot wheel that has produced some of the largest slot payouts ever recorded, and wrap it in a more visually elaborate package than the original. For players who come specifically for the jackpot chase, everything they need is here, competently delivered.
The game uses a cluster pays format rather than fixed paylines, set against an elaborate underwater civilisation backdrop. Bet sizes run from $0.25 to $125, positioning it slightly above true bargain-basement entry without being exclusionary. The visual production is polished in Microgaming's reliable fashion — detailed environmental animations, rich colour palette, symbols that read clearly against the background without the kind of visual noise that plagues some progressive titles.
Atlantean Treasures: Mega Moolah has a return-to-player (RTP) of 92.05%. That is a little below the roughly 96% average for modern online slots. RTP is a long-run statistical figure measured over millions of spins, not a guarantee for any single session.

Atlantean Treasures: Mega Moolah is Microgaming’s 2020 attempt to bring their famous progressive jackpot network into an underwater kingdom setting. The idea is straightforward — take the Mega Moolah jackpot wheel that has produced some of the largest slot payouts ever recorded, and wrap it in a more visually elaborate package than the original. For players who come specifically for the jackpot chase, everything they need is here, competently delivered.
The game uses a cluster pays format rather than fixed paylines, set against an elaborate underwater civilisation backdrop. Bet sizes run from $0.25 to $125, positioning it slightly above true bargain-basement entry without being exclusionary. The visual production is polished in Microgaming’s reliable fashion — detailed environmental animations, rich colour palette, symbols that read clearly against the background without the kind of visual noise that plagues some progressive titles.
The bonus structure follows the Mega Moolah template closely. The same four-tier jackpot wheel — Mini, Minor, Major, Mega — sits at the heart of the prize architecture, triggered randomly during play. The probability of triggering increases with stake size, but it fires independently of any particular game event rather than through a deliberate mechanical trigger. Free Spins with a 3x multiplier applied to all wins add a layer of base-game reward beyond the jackpot chase, giving regular play sessions some upside that doesn’t depend entirely on wheel activation. The progressive Mega jackpot is the primary reason to play this title, and it can reach genuinely life-changing amounts depending on the current pool.
The published base RTP is 92.05%, lower than most standard slots — a common trade-off with progressive jackpot titles, where a meaningful portion of each wager feeds the prize pools. Volatility is medium, meaning the base game pays with reasonable regularity when the jackpot isn’t in play. The max win is tied to the current progressive pool rather than a fixed multiplier, which is the central appeal.
Atlantean Treasures: Mega Moolah is the right choice for players who want Mega Moolah jackpot potential in a fresher visual environment. The lower base RTP is the known trade-off, and players approaching this slot should be clear that the jackpot prize pool is the primary draw rather than the base-game structure.
