Mega Moolah Online slot by Microgaming is officially the most lucrative online slot machine in history, having turned over 60 people into instant multi-millionaires and holding the current Guinness world record for the largest jackpot payout from an online slot machine game. This famous slot is safari-themed, boasting an African savannah feel with simple, humorous animal faces serving as symbols, a distinctly African soundtrack and sun-baked grass plains with thick trunked-trees making up the backdrop to the reels. This title offers wilds, free spins and a chance at not one, but four progressive jackpots to put you on the trail of historic winnings.

Game Symbols

  • The lower value symbols are cheerfully coloured 10, J, Q, K and A card suit icons, with the Ace paying out the most at 150x your bet for 5 on a line.
  • The higher value symbols take on the guises of cheeky looking Elephants, Water Buffalo, Zebras and an Antelope. The Antelope is the most tight-fisted of the symbols, paying out 250x your stake for 5 on a line, while the Elephant thunders in at 750x your stake for 5 symbols on a line.
  • The wild symbol is a Lion which pays out an impressive 15 000x your bet if you get 5 on a line, as well as substituting for any regular symbols to form winning combinations and adding a bonus 2x multiplier.
  • The scatter is an unhinged-looking purple monkey with a jewelled headpiece which trigger’s the slot’s free spins mode.

Bonus Features

Free Spins

The free spins mode is triggered by lining up 3 or more monkey scatters. The reels then turn from brown to black and you are instantly given 15 free spins and a 3x multiplier for all the winnings you collect while the feature is active. If you are lucky enough to land 5 of these symbols, you will also receive 100x your wager.   Free spins can be re-triggered by the appearance of more monkey scatters during this round.

Progressive Jackpot

Getting to this slot’s history-making bonus feature is a matter of pure luck. The bonus game can trigger at any point during the base game. The reels disappear to be replaced by a wood-framed Jackpot with a lion’s paw print etched into its centre. To the left of the wheel, colour coded panels display the amounts for the Mega, Major, Minor and Mini progressive jackpots which start at $10, $100, $10 000 and $1 million respectively. The wheel spins and you can land on one of 20 coloured segments that correspond to the different jackpots. The Mega Jackpot is represented by a single, white segment, making it an understandably elusive prize with only a 5% probability of landing on the prized segment, every time you get to spin the wheel.  Catching the mini jackpot is much easier, with your chances standing at 50%. As the jackpots are all progressive, the potential to surpass the starting amounts is all but guaranteed.  

The Winner's circle

The Mega Jackpot has been won a total of 61 times in the slot’s 14-year history.  2017 was a bumper year, producing 13 mega winners. 2019 came within a hairs width of that performance, creating 12 mega jackpot winners. The 2015 £13.2 million mega jackpot win by UK resident, Jon Heywood, is what got this slot into the record books and nobody has succeeded at surpassing this yet. 2019’s final winner came out of New Zealand to claim a prize just shy of $5 million but was by no means the year’s biggest winner with a lucky Canadian player taking home an eye-watering $20,059,287.27 in January of the same year.

Our Verdict

The Mega Moolah slot is definitely a broad appeal game. It has a solid base game with a rewarding free spins mode that will charm casual gamers, and it holds a coveted prize for jackpot seekers.  The graphics and animation are dated, but the game’s popularity has seen it weather its fair share of competitors.  

The base game stands on its own as an exciting affair, offering a top-end possible win of up to 45000x your stake for the ultimate combination of landing 5 wilds in a line during free spins mode. The progressive jackpot’s allure is simple enough, catching the Mega segment on the right day could mean a fortune that changes your life forever. The game’s low RTP and medium volatility might put you off if you are a fan of fast and frequent wins, but Mega Moolah’s top prize might just change your mind.
