Game Information


Special Symbols - Book Wild/Scatter Symbol: The ancient book serves as both the scatter and wild. This symbol is multifunctional, acting both as a substitute for any symbol to help form winning lines, and as the key to unlocking the Free Spins feature.

Progressive Trigger Coins: These special coins are your ticket to the thrilling Jackpot Bonus feature. Accumulating these coins throughout gameplay enhances your chances of triggering the feature, where one of four progressive jackpots awaits. Each coin is adorned with a distinctive lion's head.

RTP - 92.01%, which is about right for a progressive jackpot slot of this magnitude.
Volatility - High, which means you may need to exercise patience while waiting for the payouts to come, but they'll probably be worth it when they do.
Free Spins Feature - The Free Spins Feature trigegrs when at least three Book Wild/Scatter symbols make an appearance across the reels, initiating with 10 free spins. Prior to the commencement of these spins, a symbol is chosen at random to assume the role of an expanding symbol. This symbol, upon landing, has the potential to expand, covering entire reels. When this happens, some colossal payouts can occur.
Jackpot Bonus Round - Ultimately, the jackpot round is triggered randomly. However, collecting coins makes it more likely. Each segment of the wheel is linked to a specific jackpot, with the Mega Jackpot being the crown jewel, starting at a staggering £2 million.


The Book of Mega Moolah slot captivates with its blend of adventurous African safari theme and the allure of progressive jackpots. While the base RTP might seem modest, the prospect of hitting the Mega Jackpot, along with the engaging Free Spins feature, makes it a must-try for both jackpot hunters and slot enthusiasts. The potential to win the progressive jackpot is really what this slot is all about. Check out some other Microgaming slots here.
