Book of Sun bonus features

As game designs go, Book of Sun offers some familiar visual motifs. The casino game screen is set against a backdrop of a stone temple. By way of symbols, we can see A, K, Q, J and 10 on the lower end of the paytable. A pharaoh and Horus, the hawk-headed god of Egyptian myth, are the more generous symbols, as is the scarab and the jewelled eagle.


In Book of Sun, there isn’t a Wild symbol as such but a Wild-Scatter combination, represented by the golden book (presumably the book referred to in the game’s title). The gold book acts like a Wild, substituting for all other symbols except the Expanding Symbols during free spins.

The book also doubles as a Scatter, and when 3 appears on the same spin during the main game, the free spins feature is triggered.

Book of Sun Free Spins

Once three or more books have landed simultaneously, the free spins feature is launched, with the player receiving 12 free spins initially. Should 3 or more golden books land during the free spins rounds, another 12 spins are added to the player’s tally.

At the start of the free spins feature, one symbol on the reels is randomly selected. This symbol will then become the Special Expanding symbol for the duration of the feature.

If a win is triggered, any instances of the selected symbol will automatically expand, increasing the chances of hitting more winning combinations.

Book of Sun jackpot

The Book Of Sun slot not include a jackpot feature.


Book of Sun has an RTP value of 95. This makes the game appealing to players who enjoy a measure of risk in their gameplay but who are also keen on stretching their bankroll to ensure they get to play for as long as possible.
