Book of Mega Moolah Online Slot Review

The Book of Mega Moolah slot is an African wildlife themed game where you can win one of the biggest progressive jackpots in the world. Played out over 5 reels, 3 rows, and 10 paylines, it returns to the original Mega Moolah theme and symbols, with lions, giraffes, and elephants featured alongside playing card symbols.

A book is both the wild and scatter symbol here, acting as others if needed and unlocking free spins with special expanding symbols that pay on any reels. The highlight is the randomly awarded Mega Moolah feature where you can win any of 4 progressive jackpot prizes. The top-tier Mega prize seeds at 2,000,000.00 and has been known to hit 12,000,000.00 or more.

It’s a high volatility game with average returns of 86.71%, which is fairly typical for a progressive jackpot slot. Play the Book of Mega Moolah slot machine on PCs or mobiles at the top Casino Sites and you can win up to 5,500x the stake in the main game, and many millions from the progressive feature.

How to Play the Book of Mega Moolah Slot Online

Jungle drums and birdsong welcome you to the plains of Africa, where you find cartoon wildlife symbols alongside colourful high card symbols 10 through to A. It’s a retro style that has changed little from the original Mega Moolah slot first launched in 2006. Despite the older design, it’s a bright, cheerful game with some nice animations from winning symbols plus a detailed backdrop of trees and piles of gold littering the grasslands. 

The controls are easy to use across PCs, Android, iOS, and Windows versions at the best Betting Sites. You can tap the stack of coins button to reveal staking options from 0.10 to 25.00 per spin which equals a range of 0.01 to 2.50 on each of the 10 paylines that run from the left reel. 

The paytable, reached via the 3 small lines above the reels, has a list of symbol values and details of how features such as the Mega Moolah jackpots work. You need a minimum of 3 playing card symbols to win, or just 2 examples of any animal to collect a prize. The lion is king of this jungle, and he pays 1x times the stake when he lands on 2 reels on a line, increasing to 500x for a full set of 5 on a payline.

Progressive Jackpots & Other Book of Mega Moolah Slot Features

A green book can substitute for any other if it’s in the right places to complete or improve a winning combination. It’s also a scatter symbol that pays 2x, 20x, and 200x your stake when seen in any 3, 4, or 5 places respectively. 

You get 10 free spins of the Book of Mega Moolah slot machine reels from any 3 or more scattered books and before they begin a random symbol is chosen to expand throughout the round. It will only expand if it can make a win, but the selected symbol doesn’t need to be on adjacent reels, making a prize more likely. Free spins retrigger if at least 3 books land at once. 

Of course, we’re all here to win a vast progressive jackpot prize, and they don’t get much bigger than Mega Moolah which features across many Games Global slots. It’s a randomly awarded feature where you spin a jackpot wheel that stops on any of 4 prizes. The Mini, Minor, Major, and Mega jackpots seed at 10.00, 100,00, 10,000.00 and 2,000,000.00 in that order. These increase in value as a small portion of all stakes placed across the Mega Moolah network is put aside until someone wins the prize and it resets to the base value.
