This isn’t the first “Book of” Spinomenal free online slot, and it’s certainly not the first game we’ve seen inspired by Ancient Egypt. Book of Mad Money takes a common theme and places it on a fairly simple 5x3 grid with just 10 paylines. It’s an almost comfortable design, but the rousing music and thrilling features bring real sparkle.

Theme, Graphics & Soundtrack

If you take online slots as your guide, you’d be forgiven for thinking that Ancient Egyptian society consisted of nothing but pyramids full of endless treasure. And whilst not every archaeological discovery in Egypt is on the scale of King Tut’s tomb, the potential for gold and other marvels is part of what has held this long-buried civilisation in the popular imagination for thousands of years.

One important aspect of Egyptian culture was the Book of the Dead, an essential part of allowing a person to travel through the underworld and to the afterlife. That title has already been taken by a slot, so here we have the Book of Mad Money instead. Like Money Train 2, it can’t help reminding you about potential prizes.

It is still about the dead, though, set in a vast chamber where elaborate pillars and statues crack with age and the ground disappears under piles of gold. Symbols like scarabs, pyramids and the Book itself are vividly drawn, flashing with bright light if you win, and the music promises an adventure.

Book of Mad Money RTP and Variance

Brace yourself. The RTP of Book of Mad Money is only 94%. That is pretty low by the standards of modern online slots, but don’t just write the game off yet. The thing about averages - and RTP is only an average - is that there are always exceptions. 

Still nervous? With free casino slots, you can get a feel for gameplay and returns without putting actual money on the line. As Book of Mad Money has a slightly risky medium to high variance, the chance to play for free is even more valuable.

How to Play Book of Mad Money

Can you win any of the treasures in this tomb?

  1. The best way to understand the Book of Mad Money slot is to read the rules and paytable, which you’ll find behind the question mark button.
  2. Free casino slots still require a bet of virtual money, so use the plus and minus symbols to adjust it in line with your budget and taste for risk.
  3. Another part of your budget is loss and single win limits. Keep your game under control and make sure you walk away happy. Have them in mind before you start, and take a breather every so often to make sure you don’t forget them.
  4. Other settings include full screen, sound and turbo, which are located in the bottom corner.
  5. The main spin button is at the centre and framed by the buy feature and autoplay (continuous spins that don’t stop until you hit stop, regardless of limits). Have fun!

Always play responsibly.

Bet & Win Sizes

The bet adjustor takes your bet per line from 0.01 to 10. That means a total bet of between 0.1 and 100.

10, J, Q - x100

K, A - x150

Wild scatter book - x250

Pyramid, Scarab - x750

M crown - x2000

Book of Mad Money Bonus Features

Some of the best online slots are those with bonus features, and in the Book of Mad Money online slot, they’re certainly a highlight:

Free Spins

It starts with the free spins round, which, as in many slots, can be triggered with 3 scatters. You’ll be awarded 10 free spins and have the opportunity to retrigger another 10. What makes it extra interesting is the arrival of a special wheel, which you have to spin to activate a second bonus feature.

Expanding Symbols

That wheel can be used to decide which symbol will be your expanding symbol for the rest of the free spins round. That means that when a symbol you need to complete a payline lands in the wrong position, it may be able to grow until it covers that spot, too. That means more chances to win.

If you’ve followed our Book of Mad Money slot review so far, you probably have a pretty good feel for this game already. It’s a familiar theme but pretty well designed, with some exciting layers of bonus features.

What is the RTP of Book of Mad Money?

This is easily the most disappointing aspect of Book of Mad Money. The long-term average return has been calculated at 94%. Most slots that we enjoy playing are at least 96%. Of course, it’s very rare to have an average session on a slot. There’s room for deviation, both higher and lower. Nothing is guaranteed.

What is the variance of Book of Mad Money?

Something else that may make the more cautious players pause is the fact that Book of Mad Money has a variance that is between medium and high. Medium slots are fairly balanced between the size and frequency of their wins, but the high-volatility games increase potential rewards by increasing the risk. Wins may be larger, but they’ll also be rarer.

Does Book of Mad Money have a free spins bonus round?

One of the best parts of this game is that when you find 3 scatter symbols, it means you’ll just be given 10 free spins where you can keep playing without any new bets. Even better, during the round, you can spin a wheel to choose an expanding symbol in the form of an icon that will grow when you need it to complete a line.
