Book of Sun is a quality Egyptian-themed slot machine developed by Booongo.
Booongo once again invites us to go on an exciting journey through Ancient Egypt by playing the Book of Sun slot. But as soon as you open it, you will immediately realize that this is an excellent copy of the famous Book of Ra slot from Novomatic. But, to be fair to Booongo, I would like to say that they are far from the first to decide to release a slot with a similar theme and gameplay. For example, the developers of Play'n GO also created a very successful and modern version of this slot called Book of Dead.
As mentioned above, the Book of Sun slot machine is made in the Egyptian style and invites you to find the long-lost riches of the ancient pharaohs. If you have already played slots created according to this principle, then the design will be familiar and understandable to you, since it does not offer anything new. As always, the playing field is located at the entrance to the Egyptian pyramid, with huge columns standing on the sides. On the technical side, the Book of Sun slot machine is also nothing new, you will get five reels and only 10 lines to form your winnings, and the range of bets provided here can be from 0.20 euros per spin. The symbols that you will meet on the playing field in Book of Sun will also be familiar to you. Less valuable are card names from 10 to A, followed by a bird and a scarab. The god Ra is of great value, and finally the most valuable symbol in the slot is the Egyptian pharaoh. As in all similar models, the Book is the most important symbol in the game, because it performs two roles of a wild and a scatter symbol at once. This means that it can substitute for all symbols to form winnings more often, as well as activate free spins when dropped in the right amount.
If you have already played slots with similar mechanics, then you probably know what you can expect from the gameplay. As in all similar models, the only and main feature is the free spins round. It can be activated after three scatter symbols (Book) appear on the playing field. Once this happens, in addition to a cash reward of 2x, 20x or 200x your stake for three, four or five of these symbols, you will have access to 12 free spins. And by the way, this moment is different from previous models, in which the number of free spins did not exceed ten.
So, as soon as three scatter symbols appear on the playing field, you are guaranteed to get 12 free spins, before launching which one random symbol will be selected, it will act as an expanding one. This special symbol will expand every time it appears on the playing field in a certain amount. The only symbol that cannot expand in the free spins feature is the book. Also note that if three more scatter symbols appear on the playing field during the free spins round, you will receive an additional 12 free spins.
Summing up, I would like to say that Book of Sun is an excellent slot machine from the developers of Booongo, which, despite its insane resemblance to the Book of Ra slot, looks high quality, interesting and definitely deserves your attention.
