Mega Moolah

The flagship progressive jackpot slot with the biggest prize of all is Mega Moolah which has now expanded beyond the original 2006 game to a whole series of versions and even has inclusion of some of the biggest slot game names from Microgaming.

Mega Moolah is played on a 5 reel 3 row board and 25 paylines, with an RTP of 93.42% which player should be aware of, this is much lower than most slots, but what makes Mega Moolah different is that the jackpot can be won by playing any stake from 25p upwards rather than being reserved for players using maximum stakes.

Mega Moolah was originally released in November 2006 and stood alone until May of 2009 when titles like Summertime and 5 Reel Drive were added to the Jackpot series.

Since then, a further 7 titles have been added, taking the full series to 9 Mega Moolah slot games.

Immortal Romance

A vampire-themed slot, Immortal Romance includes wild symbols, scatters for tiered free spins play at 243 ways to win in a medium volatility slot with a top win of 12,150 x and a randomly triggered Wild Desire bonus feature that can pay the biggest wins.

Before explaining the tiered bonus rounds, I should mention terrific game graphics, and an excellent soundtrack, particularly through the bonus rounds.

Immortal Romance Scatter Free Spins

There are four levels of free spins awarded when landing, 3,4,or 5 scatter symbols on the standard board. And each tier of free spins is named after one of the four premium characters in the game, namely, Amber, Troy, Michael and Sarah.

You need to land the scatter bonus 5 times to rise through the ranks and play the next bonus round with differing features.

BonusFree SpinsFeature
1Amber 10 Spins5x Wins
2Troy 15 SpinsUp to 6x Multipliers
3Michael 20 SpinsCascading Wins
4Sarah 25 SpinsUp to 14 Wilds added


All bonus rounds can retrigger as scatters land.

Wild Desire feature

The Wild Desire feature is a random bonus, and can turn each reel into a stacked wild. Obviously, 5 wild reels are the maximum but expect 1 or 2 most of the time.

Game of Thrones

It was inevitable that one of the biggest TV series in history would also produce a slot title and Microgaming was the one to build and release. 

Offering 243 ways to win board of 5 reels and 3 rows with around 95% RTP with a medium volatility rating meaning wins can be frequent and low value with the odd high-value win landing, but most good wins coming within the bonus free spins round.

Free Spins Bonus

Land 3 or more of the Game of Thrones logos to trigger the Free Spin round where you have a choice of four options by choosing a house

  • Baratheon house 8 free spins, wins x5
  • Lannister House 10 free spins x4 multiplier
  • Stark House 14 free spins x3 multiplier
  • Targaryen House 18 free spins

Scatter Bonus

Land two scatter symbols anywhere on the reels, and you'll be awarded a random multiplier of your total bet.

  • No. of slots 2000
  • Payout speed 24 Hours
  • Win rate 96.3%

Book of Atem

The Book of Atem offers 10 paylines across 5 reels with a 96.4% RTP High Volatility game on an Ancient Egypt theme and a top win of 5000x

Part of the WowPot jackpots game series, it holds the record for the biggest WOWPot paid to date by Microgaming of Over €17,000,000

Free Spins

The free spins round provides one symbol which will appear highlighted on the reels, and if you land 3 or more, they convert to stack and pay as they would if they were lined up left to right. This is pretty much the same style as Book of Dead and a host of other titles, that have this free spins feature, so if you are a fan of those, this will please you in the free spins rounds.

The one thing we might say that does make this a better game than Book of Dead is the RTP which i slightly higher, otherwise, it will be a decision based on graphical appeal and/or musical accompaniment.

Book of Oz

Book of Oz has a couple of titles in the series now, but here we concentrate on the original game.

Playing 10 Lines across 5 reels and 3 rows, with medium volatility at a 96% RTP, the top win on Book of Oz from Microgaming is 5000x

The attractive thing about this game is actually its simplicity. Microgaming do produce some of the most immersive and technically brilliant slot games, but Book of Oz, is really straightforward.

Expect similar bonus free spins rounds in the vein of Book of Atem.

What makes Book of Oz unique however is the option to respin the reels after a losing spin. This isn't a free option you have to understand, it will come at a cost, based on the probability of landing a win on the spin.

You can choose to ignore this - I would - and start a fresh spin at your normal stake

Microgaming WowPot Jackpots

The WowPot from Microgaming launched in February 2020 and provides a progressive jackpot with 4 tiers of prizes paying out over €50,000,000 in prizes as of June 2021.

The WowPot has a significant €2m seed amount and is supported by the Major, Minor, and Mini posts too.

The Wow pot has been won on 5 occasions since its launch. The biggest WowPot win to date is an incredible €17,529,047.11 won on the Book of Atem slot in April 2021 - can you even imagine?
