This time, it has released a sequel to one of its most popular slot games, Mega Moolah, to bring you Book of Mega Moolah! Players will find themselves back on the African Serengeti Plains where they will spin reels filled with African safari animals. Bonus features in this game include a wild symbol which also doubles as a scatter symbol, a free spins round with an expanding symbol feature in play and, of course, the jackpot feature. In the jackpot feature, players are guaranteed to win one of four progressive jackpots which can range from as little as £10 up to over a whopping £2 million.

If you think this could be the slot game for you, carry on reading our Book of Mega Moolah review for all the information you need to know about this game.

How to Play

Once your bet is set, hit the white arrow button to send the reels tumbling. Bets per spin start from just 10p and can rise to £25. Winning combinations are formed by landing three or more matching symbols on consecutive reels, starting from reel one.

The symbols on the reels of this game are:

  • 10
  • J
  • Q
  • K
  • A
  • Giraffe
  • Buffalo
  • Elephant
  • Lion
  • Book wild and scatter


In the base game, the lion is the highest value symbol on the reels and it can award up to 500x your stake for five in a winning combination. As this is a progressive jackpot game, there are four jackpots up for grabs, the highest of which starts at wins of £2 million.

Special Features

There are three special features in the Book of Mega Moolah slot game including a wild symbol, a free spins feature and a jackpot bonus feature.

The wild symbol is the paw print green and gold book. Not only is this the wild symbol, but it also doubles as the game’s scatter symbol. As the wild symbol, it can substitute for other symbols on the reels to help form new winning combinations and potentially award larger cash prizes.

When three or more of the book wild/scatter symbols land on the reels, this will activate the free spins bonus round plus an initial pay out is awarded:

  • 3 book scatters – 1x
  • 4 book scatters – 10x
  • 5 book scatters – 100x

Players are awarded 10 free spins and a random symbol is chosen to become an expanding symbol. This symbol can expand to cover entire reels when it is part of a winning combination. If the lion becomes the expanding symbol, this can result in wins of up to 5,000x your bet.

The highlight of Book of Mega Moolah is, of course, the huge progressive jackpot up for grabs! Throughout the game, you can collect progressive trigger coins which can then result in the jackpot feature randomly triggering. During this round, players are guaranteed to win one of four progressive jackpots. Spin the jackpot wheel to be awarded one of these jackpots:

  • Mini jackpot – starts at £10
  • Minor jackpot – starts at £100
  • Major jackpot – starts at £10,000
  • Mega jackpot – starts at £2 million

Graphics and Sounds

If you have played the original Mega Moolah slot game, Book of Mega Moolah will feel familiar upon loading. Players will be transported back to Africa and the Serengeti Plains which act as the backdrop to the reels alongside a big pot of gold coins. On the reels, many familiar African animals are back to once again act as high value symbols on the reels including giraffes, buffalo, elephants and lions. The low value symbols are the standard playing card symbols in a variety of bright colours. Lively African music plays in the background as you spin which works perfectly with the overall theme of this slot game.


Most online slot players will have played the famous Mega Moolah slot and so we are sure many will want to try giving Book of Mega Moolah a spin. The graphics are similar to the original game but have been given an update and refresh to make it even better. What’s more, there are not too many bonus features in this game and it is kept simple with the free spins and expanding symbol. However, most players will be spinning its reels for the chance to trigger the jackpot and get mega jackpot win of over £2 million.
