iSoftBet presents to you a futuristic version of a well-known theme, the Ancient Egypt theme. In its new Book of Immortals slot, the developer tries to personify the immortal gods from Ancient Egypt, giving them a modern look and feel.


The Book symbol plays a dual role in Book of Immortals, acting as a Wild in certain aspects and as a Scatter in other situations. As a Wild, it replaces any other symbol on the reels in the creation of winning combos. As a Scatter, it helps you trigger Free Spins but also gives you insane payouts.

3 to 5 Scatters give you 10 Free Spins, but different payouts. Landing 3 Scatters, you get 2x the stake payout, with 4 Scatters you get 20x the bet, but with 5 Scatters on the reels, you get 200x the stake payout. During the Free Spins, the game chooses a special symbol on the top Ancient Reel. After you get your initial pays, this special symbol will expand and create winning combos on all 10 paylines on non-adjacent reels. After the Expanded symbol wins are paid, the top reel moves to select another different symbol. Gods symbols at this point become immortal and Expand and stay like that for the duration of the Free Spins. In case the Extra Free Spins symbol was selected on the top reel, you get extra Free Spins!

However, there is another cool feature which randomly triggers. With the Scarab Swap feature, Scarabs can fly across the reels during any paid spin and attach themselves to up to 10 symbols on the reels, transforming those symbols into the same, matching symbol and giving you a potentially bigger win.

Theme & Design

The blue Book symbol has a large scarab on the cover and something written in an ancient Egyptian language. You get to see the gods Anubis, Amun Ra and Apis and the goddess Bastet as the highest-paying symbols and the Ancient Egypt-styled playing card Royals as the lowest paying ones. Then, you also get the magic Scarabs flying across the reels.

In the background, you will notice that the reels are set at the entrance of an old palace, and far behind, you can see sphinxes and pyramids, and the sun shining brightly. However, as mentioned, the game was designed with futuristic drawings of the symbols, and special effects that make the graphics look ultra-modern.

Wagering & Paylines

There are 10 fixed paylines in Book of Immortals, and to place your bets, you will need to decide on the line bet value from $0.01 to $1.00. This makes the betting for 10 fixed paylines go from $0.10 to $10.00.

iSoftBet has offered an RTP of 96.31% for this game, which is great because that's the average RTP found in many slots. As mentioned earlier, when you land 5 Scatter/Wild Books, you get 200x the stake payout, which for the maximum bet would mean $2,000.00. The Gods and the Goddess can give you anything from 50x to 150x the stake payouts, which would mean up to $1,500.00. But these payouts are per round, meaning you could win a lot more with the 10 Free Spins and the extra Free Spins that you could win thanks to the special features.


Book of Immortals is a really mesmerizingly designed slot, with impressive graphics and attention to detail in the symbols drawings. Now, payout-wise, it doesn’t sound that promising, considering the fact that the developer has not set a maximum payout potential for it, and we know that $2,000.00 is the most we can get from 5-of-a-kind combos with the highest-paying symbols. Sure, that is the payout per round, and sure there are plenty of Free Spins you could win, however, we cannot be sure how much the top payout is going to be. But, if you’re interested in a casino game with cool features, theme and symbols, go ahead and try it. There is a reasonable betting range provided and an average RTP, so give it a try.
