The Book of Ra online slot machine is one of the iGaming industry’s oldest and most popular titles. It was released way back in 2005, and it is just as popular today as it was when it first arrived two decades ago.
On this page, we will be exploring some of the main reasons why this popular Ancient Egypt-themed slot endures to this day, and we will also be revealing how to find a safe site where you can enjoy playing this blockbuster title right now from your Wi-Fi/internet-connected PC or mobile device, provided you are of legal age in your country to play at online casinos.
What is Book of Ra?
Book of Ra is a feature-rich, computer-generated online slot machine that anyone aged 18 or above can play in the real money mode and free play demo mode on hundreds of legally permitted iGaming platforms.
However, in some countries, you may find that the legal minimum age to play games like this on a fully licensed and regulated casino site is slightly higher (e.g. 21 in multiple US states and 19 in several Canadian provinces).
It was developed by a company called Greentube, and it’s brought to you by a top-tier, market-leading online casino software provider called Novomatic.
Here are a few quick facts about one of the world’s most popular online slots – Book of Ra:
- Name: Book of Ra
- Game type: Computer-generated online slot/video slot
- Rows/Reels: 5/3
- Paylines: 9
- Software provider/game development studio: Novomatic/Greentube
- Min/max bet per spin: $/€/£0.01/$/€/£45.00 (may vary, depending on region)
- Platforms/device compatibility: PC/Mac/iOS/Android
- Year released: 2005
- Theme: Ancient Egypt/Egyptian Mythology/Action & Adventure
The game has wild symbols and scatter symbols (the Book of Ra symbol doubles up as both a scatter symbol and wild symbol), and the main bonus feature that players can look forward to as they spin the reels is a free spins bonus with a special expanding symbol.
To trigger the free spins bonus, 3 or more Scatter/Wild Book of Ra Symbols must land in any position across the reels on the same spin. Each time this happens, a guaranteed bonus of 10 free spins will instantly be triggered/awarded.
Before you can play in the free spins bonus, one special symbol will be chosen at random, and then each time it shows up at any point during the feature, it will always instantly expand to fill the entire reel from top to bottom.
You need three or more special expanding symbols to show up on the same spin during the free spins bonus to receive a payout, and they don’t need to land in consecutive order across the reels to win a prize.
To ensure players never miss out on landing a winner, it’s best to play each spin with all paylines active, but only if you can afford to play each spin with all paylines active.

Why is the Book of Ra online slot machine so popular, even to this day?
The Book of Ra slot has remained popular with older and newer audiences for various reasons. For example, the likeable adventure-seeking Indiana Jones-style lead character and the game’s popular Egyptian Mythology/Ancient Egypt theme are two key components that many online slot machine enthusiasts tend to look for in slots.
Other popular online slot machine theme examples that are just as popular as the Ancient Egyptian theme include Greek Culture/Mythology, Sports, Horror, Sci-Fi, Norse Mythology, the Wild West, and Luck O’ The Irish/Leprechauns.
Over the years, the game has achieved iconic status, which very few games have the ability to do these days. In other words, it has become a true classic, and many people actively seek out this game, just like they seek out other hit titles, such as NetEnt’s Starburst online slot, Microgaming/Games Global’s Mega Moolah online slot, and Play’n GO’s Book of Dead online slot.
It’s a high volatility slot, which many players look for these days, and its simple mechanics, payline structure, betting options, and general gameplay features and bonuses combine to make this an ideal game for everyone from beginners to seasoned pros.
The Book of Ra’s fun sound effects and retro, slightly outdated graphics and animated sequences also give it its unique charm, which has further cemented its status as a modern classic. Many online casino websites also give players free spins or free matching deposit bonus money to try this game when they sign up and deposit for the first time.
