Book of Mega Moolah Overview
Book of Mega Moolah was launched in 2023 by Games Global and combines two of the most beloved slot styles in online gaming: the ‘Book of' format and the Mega Moolah jackpot system. At its core, this is a 5-reel, 3-row, 10-payline slot with high volatility, meaning that while wins may be less frequent, the payout potential is notably higher.
The Mega Moolah series itself has a rich legacy. The original Mega Moolah game launched in 2006 and quickly rose to fame for its massive progressive jackpot prizes. It became one of the first online slots to regularly produce millionaires, including setting records for some of the biggest online wins ever. Since then, the series has expanded into multiple themed titles – from jungle and underwater settings to magical realms – all tied together by the same thrilling jackpot network. Book of Mega Moolah continues this tradition, layering in the popular expanding symbol mechanic from the ‘Book of' genre to create something fresh and rewarding.
Visually, the game leans into an African safari theme, filled with rich imagery and an ambient soundtrack that complements the setting. With a minimum bet of 0.10 credits and a maximum of 25 credits per spin, players can adjust their stakes to suit their bankrolls.
The game plays smoothly across all devices and uses a clean interface, which allows players to navigate with ease. But the real draw lies in the layered gameplay: from standard symbol payouts to expanding symbols in the bonus rounds, and of course, the randomly triggered jackpot feature.
Game Symbols
Book of Mega Moolah features a visually rich reel set that reflects its safari theme. The lower-paying symbols are represented by playing card values from 10 through Ace, each adorned with a tribal motif to blend with the African adventure aesthetic. These symbols offer smaller payouts but appear more frequently, helping to maintain consistent action during gameplay.
The high-paying symbols are where things get more exciting. They include animals iconic to the African savannah: buffalo, giraffes, elephants, and lions. The lion stands as the highest-value symbol in the base game, paying up to 12,500 credits when five land on a payline at maximum bet. These symbols don’t just deliver bigger wins – they also contribute to the visual storytelling of the game.
The Book symbol is especially important. Serving dual functions as both Wild and Scatter, it substitutes for all other symbols to help form winning combinations and also activates the game’s central bonus feature. Once three or more Books appear on the reels, not only does it result in a payout but also launches the Free Spins round.
One notable element of the payout system is the potential for large wins during Free Spins thanks to the expanding symbol mechanic. When a high-value symbol like the lion is selected to expand, even a partial match across the reels can lead to significant rewards.
Bonus Features
What truly elevates Book of Mega Moolah is its compelling bonus round. Getting three or more Book symbols triggers 10 Free Spins. Before these spins begin, a special expanding symbol is chosen at random from the paytable. Whenever this symbol appears during Free Spins, it can expand to cover the full reel, dramatically increasing your chances of scoring big. Even better, these symbols pay on all lines – not just adjacent ones – which gives players the potential to fill the screen with high-paying icons.
The expanding symbol is only activated if a win is possible, meaning the mechanic always has a meaningful impact. It’s worth noting that the Book symbol itself cannot be selected as the expanding symbol, ensuring that other symbols step into the spotlight during the bonus round. Additionally, the Free Spins feature can be retriggered by landing another three or more Book symbols, keeping the excitement going.
While the base game is enjoyable, the bonus round is where things heat up. The anticipation of triggering Free Spins combined with the potential for screen-filling wins adds a new layer of depth. And all of this sits alongside the real star of the show – the progressive jackpots, which can be activated randomly at any time.
Book of Mega Moolah Jackpots
Book of Mega Moolah forms part of the legendary Mega Moolah progressive network, meaning players have a chance to win one of four progressive jackpots: Mini, Minor, Major, and Mega. Each of these jackpots starts at a base value, but because they are fuelled by contributions from every spin made across the network, they continue to grow until claimed.
The Mini jackpot kicks off at 10 credits, offering a modest reward. The Minor kicks off at 100 credits and is more commonly won, making it a satisfying boost. The Major starts at 10,000 credits, providing a thrilling payout for any player lucky enough to land it. And then there’s the Mega jackpot, which begins at a staggering 2 million credits and has the potential to climb even higher, making it one of the most sought-after prizes in online gaming.
What makes the jackpot feature especially enticing is that it can trigger at random during any spin – no special combinations or bonus symbols required. Once triggered, players are taken to a separate screen where one of the four jackpots is guaranteed to be awarded. This sense of unpredictability adds a further element of excitement to every spin
