A Review of the Book of Sun Slot Machine

The first thing most people notice about this slot title is its familiarity with Novomatic’s Book of Ra Deluxe. As a new addition to the “Book of” series created and inspired by Novamitic’s game, has this slot title met or exceeded the expected standards?


  • Its expanding symbols and bonus features allow substantial wins, especially during free spins rounds
  • It is mobile-friendly
  • Free spin can be triggered


  • Max bet is not for true high rollers
  • There is no jackpot

The plot of the Book of Sun

Just like many online slots in the “Book of” series, the Book of Sun follows an Egyptian theme, taking us on an immersive adventure in ancient Egypt. Gamers are expected to discover the riches of Chorus and ancient Pharaohs. All the secrets are hidden in the Book of Sun, and only those who know how to decipher it will stand the opportunity to have the maximum wins in a single spin.

Book of Sun gameplay

This casino title has a layout of five reels and up to ten pay lines. It also has very easy-to-follow instructions and is suitable for mobile play, desktops, and laptops. The reels are set at the temple entrance between two massive pyramids, and gamers need to recognise all the symbols surrounding the reels quickly.

Graphics and animation

The theme of this game is very common with online slots. However, the providers did a good job with the visuals and the soundtrack, as they are very entertaining and in sync with the mission and adventures the gamers have ahead of them.

Free spins and bonus game

When you trigger the free spin feature, Book of Sun gives you 12 free spins, unlike most others that only give 10. The free spins are also retriggered if three or more golden books land during the free spins round. One symbol is randomly selected at the start of the free sin to become the special expanding symbol, and this can be any symbol except the Wild Scatter.

Putting aside the familiar theme and image of the Book of Sun slot, this Booongo title offers an unfamiliar entertaining experience that is hidden only in gameplay. Hence, it is a game worth trying out as it remains one of the most entertaining Egyptian-themed slot games online.
