Book of Babylon Slot RTP, Details & Wager Limits

The setup in the Book of Babylon slot is very straightforward. The game uses a classic 5 reel, 3 row machine which is made up of 10 paylines. To create a winning combination, you need to land 2, 3, 4 or 5 matching symbols or wilds from left to right in a payline starting from reel 1. It’s about as simple a mechanic as you’ll find.

You can open up the Book of Babylon at stake levels that range from 10p to £25 per spin. To adjust stake sizes, use the + and – buttons in the bottom right-hand corner of the screen.

The Book of Babylon RTP is 96.217% which is a slightly better than average. It comes with a hit frequency rate of 38.29% meaning over a third of spins will result in a winning combination. The volatility in this ancient adventure is in the medium to high range. The most you can win from a single spin here is 5,000 x your total stake.

Theme – Audio & Design Features – head to the ancient city 


Ancient themed games usually mean Egypt, Greece or Rome. It’s rare to find the ancient city of Babylon as the setting for the Book of Babylon slot. For the uninitiated, Babylon was capital city of the Babylonian Empire in ancient Mesopotamia (in modern day Iraq). It was the largest city in the ancient world for a time and is best known for its Hanging Gardens which are one of the Seven Wonders of the Ancient World.

The gameplay here is very familiar but one area where Book of Babylon really does stand out is in its design. The sound and visuals here are terrifically well done. There’s an unusual and rather mysterious soundtrack playing while you spin which fits this rare theme well.  You won’t find many better looking and sounding slots than Book of Babylon.

A courtyard in the palace of a Babylonian king is the setting here. The reels are flanked by a pair of imposing statues. You’ll find rather elegant A to 10 royals alongside a quartet of higher value symbols inspired by the Babylonian-theme. There are 2 artworks as well as the bearded Babylonian king and a mysterious woman. The woman is the most rewarding standard symbol, paying 1, 10, 100 or 500 x your total stake if you manage to land 2, 3, 4 or 5 on a payline.

The Book of Babylon symbol serves a dual role. It’s a wild that substitutes for all the standard symbols when it makes up part of a winning combination. It’s also a scatter that can trigger the Free Spins feature if 3 or more of them land on the same spin. Landing 3, 4 or 5 Book of Babylon symbols on the same spin pays 0.5, 2 or 20 x stake.

The superb sound and visuals in the desktop version of Book of Babylon and also present in the mobile and tablet versions. The imagery here really is excellent. Combine that lush design with the simple but volatile gameplay and you have a very playable mobile slot.

Book of Babylon Bonus Features

The variety of extras in Book of Babylon isn’t enormous. The solitary bonus feature is the Free Spins feature with an expanding symbol.

Free Spins feature


Land 3 or more of the book wild/scatter symbols anywhere on the reels on the same spin to trigger the Free Spins feature. Your reward here is 10 free spins.

Before the free spins start, 1 symbol is picked at random. This can be any symbol apart from the book wild/scatter. Whenever this randomly selected symbol lands during the free spins, it expands to fill the whole of that reel or better still, multiple reels.

These expanding symbols don’t need to be next to each other to form a winning combination either. This means wins are formed scatter style. If you landed matching symbols on reels 1, 3 and 5 on the base game it wouldn’t create a winner. Land that same combination in the free spins though and you would be in line for a payout.

Your potential payouts depend on which symbol is chosen to become the expanding symbol. The higher the value of the symbol, the bigger your potential wins:

Symbol(s) Max Win (Full Screen)
Q, J or 10 100 x stake
A or K 150 x stake
Artworks 750 x stake
Babylonian King 2,000 x stake
Female Character 5,000 x stake

Landing 3 book wild/scatter symbols on the same free spins delivers a retrigger. Another 10 free spins are then added to your tally. You can retrigger the free spins up to 3 times meaning up to 40 free spins can be played in total. That’s it’s as far as gameplay goes.

In case you’re wondering, the gameplay is identical to that in Book of Ra Deluxe (Novomatic) and Book of Dead (Play ‘n GO) which isn’t a bad thing as these 2 games are very popular.

Book of Babylon Review Summary – beautifully designed ‘Book of’ slot  

I’ve seen the free spins with expanding feature in countless slots (many with an ancient Egyptian theme). There’s nothing very innovative about the Book of Babylon slot. What does make this game stand out though is the lush sound and visuals which are fantastic.

The key to winning big is to get a high value expanding symbol in the free spins. Other than that, it’s another ‘Book of’ game unfortunately. It all boils down to what theme/graphics you like. It’s only normal these days that every provider has this type of game. This is Green Jade Games’ version.

If you want a ‘Book of’ game with a twist, try the Book of Shadows slot by Nolimit City which is played on 10, 15 or 20 paylines (your choice). There are also free spins and special expanding symbols but it offers 30,338 x stake wins. Alternatively, try your luck with Book of 99 (Relax Gaming) which comes with an unheard of 99% RTP rate.
