With a background on the desert, with the pyramids of Giza on the background, this slot couldn’t have a more classic appearance. There is something special about it tho, and that is of course the Infinity Reels™ mechanic which creates a completely different experience on your reels.

Bet Range and Paytable


This Book-of slot is not the only one covering the Ancient Egypt theme, one of our favourites to explore the same imaginary is Giza Infinity Reels, one of our favourite slots in the famous series. But there are so many other Ancient Egypt brilliant games, we cannot stop ourselves from mentioning huge hits like Rise of Giza Powernudge or Pharao’s Fortune.

Looking at the paytable we see lower paying symbols being royals from J to Ace. Higher-paying symbols, on the other hand, are the Egyptian amulet, a sword, an Egyptian Queen, a Lion and of course the Pharaoh. The Golden Pharaoh is the highest-paying symbol on the paytable, awarding 0.25x the stake for each symbol in the winning combo (keep in mind that thanks to Infinity Reels, these combos might be quite long).

There are no surprises also on the front of special symbols. The WILD substitutes for all other symbols but the Book symbol, helping you in the forming of winning combos. The BOOK Symbol is the scatter and triggers the free spins bonus round.

Free Spins

On top of the many special features implemented in the Infinity Reels mechanic, this slot offers an interesting Free Spins special feature. At the bottom of the reels, you will see a map showing how many reactions you need in order to trigger the free spins bonus round. If you manage to reach your goal, you will be awarded 10 Free Spins. You can re-trigger the free spins bonus round by landing more Book symbols during the feature.

At the beginning of the special feature, one symbol is randomly selected and will act as the Growing Symbol. If it lands on the rightmost reel, the symbol will add a reel (no matter if it improves the winning combo or not). On top of that, if you land 2 of these symbols at the same time, they will expand to become full reel symbols.

Our Verdict

book of infinity™ win

We are not particularly excited about Book of Ultimate Infinity by SG Gaming. We found this slot quite boring and we truly believe you can find better titles if you are in the mood for Ancient Egypt Book-of slots.
