Our expert casino reviewers have tried and tested hundreds of casinos and unearthed the following as the best places to play Book Of slots. Below, you’ll find our curated list of casino sites offering the most impressive selection of these iconic games alongside the best welcome slots bonuses and sign-up offers.
What are Book Of Slots? Popular Slot Mechanic
The ‘Book of’ series is a hugely popular category in the world of slots, found on many top casino sites. It all began with Book of Ra, launched in 2005 by Novomatic as a land-based casino game with a popular Egyptian-theme. Once it transitioned online in 2004 the game skyrocketed globally and is still to this day, a staple among online casinos.
Boasting an easy to understand mechanic, Book Of slots would soon become one of the most recognisable features in the industry with the ancient book serving as the iconic centerpiece of many titles. Book Of slots have been celebrated for their engaging gameplay which made bonus rounds more exciting and volatile. The most common thread linking all Book Of slots is in the Free Spins round, where a randomly selected special expanding symbol becomes the focus. This unique mechanic allows the chosen symbol to expand across the entire reel, increasing the number of winning ways that it is a part of and boosting the potential for big wins.
Beyond this, some Book Of games also introduce Respin features, with a few offering unlimited respins for added excitement. These mechanics have become a hallmark of the genre, keeping players entertained with their potential for thrilling payouts and they are regarded as some of the most volatile slots available.
Classic examples of this slot style include Book of Ra, which launched the genre, Book of Dead by Play’n GO, a fan-favorite globally, and Legacy of Dead, a compelling follow-up.
Whilst early releases with the mechanic stayed true to the original Egyptian aesthetic, newer variations brought fresh takes to the mechanic. An Irish-theme for example, can be found in Yggrdasil’s studio partner Reflex, Book of Blarney slot, a Halloween-theme in the Nolimit City’s feature filled Book of Shadows, as well as Push Gaming’s unique Asian-themed release Big Bam-Book.
Each offers the familiar mechanics with its own unique twists, making the Book of slots series a timeless choice for players.
