Best Mega Moolah Slots

Since the first Mega Moolah game was released in late 2006, there are now over 20 Mega Moolah slots to choose from. The iconic series from Microgaming includes jackpot versions of popular slots. Below, Chris Taylor, OLBG’s slots expert, reveals the best Mega Moolah slots.

All games give you the chance to win 4 progressive jackpots with the Mega Jackpot paying an average of €6.69 million every 49 days. 

1. Mega Moolah

The most popular jackpot slot in the world, Mega Moolah takes you on an African safari. With 5 reels and 25 paylines, this colourful slot can be played from just 25p per spin. Remastered and available to play on all devices including in Portrait Mode, Lion Wilds double your payout when part of a winning combination.

There is a Free Spins feature which is played when you see 3 or more Witch Doctor Scatters. Your reward is 15 free spins with a 3x multiplier. If the Lion Wild is part of a winning combination, it doubles the payout which effectively gives you a 6x multiplier. You can also retrigger the feature with 30 free spins available in total.

With the Progressive Jackpot Bonus Game feature triggered randomly on any spin, Mega Moolah has a 93.42% RTP rate and 1,955 x bet max wins. Finally, the Mega Moolah demo isn’t available but it is for other slots in the series.

2. Immortal Romance Mega Moolah

Immortal Romance Mega Moolah is the jackpot version of the iconic Immortal Romance slot (which is regarded as one of the best slot games of all time). With a vampire theme and one of the best soundtracks you’ll come across, you’ll play on 5 reels and 243 ways to win from 30p per spin on all devices.

There is a random Wild Desire feature where up to 5 wilds are turned fully wild. In The Chamber of Spins, there are 4 free spins features based on each of the characters. They offer 5x multipliers, Vampire Bats that double and triple payouts, Rolling Reels with an increasing multiplier up to 5x and wild symbol transformations.

With a 93.4% RTP rate, Immortal Romance Mega Moolah is exactly like the original slot but with 4 progressive jackpots. Max wins can reach 12,000 x bet.

3. Thunderstruck 2 Mega Moolah

Thunderstruck 2 Mega Moolah is the jackpot version of Thunderstruck 2, a Norse mythology classic with 5 reels and 243 ways to win. Available to play on all devices from 30p per spin, you join Thor in Asgard. The Wild Storm feature awards up to 5 wild reels but the action focuses on The Great Hall of Spins.

With 4 free spins features, there are Rolling Reels with a rising multiplier up to 5x with Thor, a 5x multiplier with Valkyrie, wild transformations with Loki and Wild Raven multipliers up to 6x with Odin. Thunderstruck 2 Mega Moolah is a medium variance slot with a 93.38% RTP rate and 8,000 x bet max wins.

4. Mega Moolah Megaways

Set in the heart of the Serengeti, Mega Moolah Megaways has 6 reels and up to 117,649 ways to win. Playable from just 10p per spin, winning combinations trigger Rolling Reels which can lead to successive wins as winning symbols are replaced by new ones.

In the Free Spins feature, you begin with at least 12 free spins. With unlimited extra free spins up for grabs, every win sees the Win Multiplier increase by 1 as well as triggering the Rolling Reels feature. The Win Multiplier can increase infinitely.

With a 92.23% RTP rate, Mega Moolah Megaways is a high volatility option with 10,000 x bet max wins. If you like the mechanic, check out OLBG’s guide to Megaways slots.

5. Book of Mega Moolah

Also set in the African plains, Book of Mega Moolah is played with 5 reels, 3 rows and 10 paylines from 10p a spin. The Free Spins feature starts with 10 free spins as well as a randomly-chosen Expanding Symbol. When it lands, it expands to fill the reels.

The higher the value of the Expanding Symbol, the bigger your win potential. If you land a screen full of Lion symbols, 5,000 x bet wins are possible on each free spin. With a 92.01% RTP rate, Book of Mega Moolah comes with 5,508.5 x bet max wins. Like free spins with expanding symbols?

6. Absolootly Mad Mega Moolah

One of the earliest slots in the series, Absolootly Mad Mega Moolah is an Alice in Wonderland-inspired game where you join the Mad Hatter on a fairytale adventure. With 5 reels and 243 ways to win, you can spin away on all devices from 20p per spin.

Using Rolling Reels with an increasing multiplier up to 5x, the Free Spins feature begins with 8 free spins. Multiple retriggers can lead to 56 free spins in total. Like the base game, Rolling Reels are in play but the multipliers are trebled meaning multipliers up to 15x. With 2,343 x bet max wins, Absolootly Mad Mega Moolah is responsible for the biggest Mega Moolah jackpot ever won: a cool €19.4 million in April 2021.

How to Win the Mega Moolah Jackpots

With all Mega Moolah slots, the progressive jackpots can won randomly from any spin. The higher your bet, the more likely you are to trigger the Jackpot Bonus feature (which is known by different names in different Mega Moolah games).

Once in, you will spin a jackpot wheel that has 20 segments and 4 different colours. Each segment corresponds to a progressive jackpot. The colours vary by slot game in the series.

Guaranteed to win a jackpot, below is a table highlighting the 4 progressive jackpots and the seed value. The latter is the minimum amount you’ll win if you win that jackpot.

Jackpot	Seed Value
Mega	£2,000,000
Major	£10,000
Minor	£100
Mini	£10

Mega Moolah Jackpot Winners

With over €600 million won, the Mega Moolah slots series is a four-tiered progressive jackpot network that has shattered and set records since Mega Moolah was released in November 2006.

The Mega Jackpot is the one you want to win as it’s worth at least £2 million (the seed value). The average Mega Jackpot payout is €6.69 million with an average timeframe of 49 days. Making it the highest-paying jackpot network of all time, there have been some life-changing jackpots won over the years. Below are the top 3:

Rank	Amount	Slot Name	When
1	€19,430,723.60	Absolootly Mad Mega Moolah	April 2021
2	€18,915,872.81	Mega Moolah	September 2018
3	€17,879,645.12	Mega Moolah	October 2015

When it comes to winners, the 3^rd highest amount won was by a UK soldier (it was £13.2 million at the time) at Betway Casino. Most winners come from Canada with 20% from the UK:

• 50% from Canada
• 20% from the UK
• 15% from New Zealand
• 10% for Europe
• 5% from Asia

Mega Moolah RTP Rates

With all Mega Moolah slot games, you will notice that the RTP rates fall below the industry average of 96%. Progressive jackpot slots tend to have a lower RTP rate than standard slot games as they factor in the jackpots.

With the Mega Moolah slots, 5.3% of the total RTP is directly linked to the 4 jackpots. To put this into perspective, £5.30 of every £100 wagering on these games will feed straight into the network. With millions of players playing, this is how the jackpots are so big.

Whilst progressive jackpot games offer you the chance to win 7 or even 8-figure jackpots, these jackpots need to be funded so the RTP is the way to do this (i.e. a % of what players wager). If you’re all about RTP rates, check out the best payout slots which have no progressive jackpots.
