Book Of Ultimate Infinity Slot Review

The Book of Ultimate Infinity Reels slot will try to unlock the Ancient Egypt mysteries using the Infinity Reels Mechanic. It would be interesting to see whether this slot has the potential to outshine the latest releases offering a similar theme. SG Games and Reel7 have decided to change the familiar scenery and provide a different plot twist to the public. How does the Infinity Reels mechanic work, and how it changed the traditional slot reel design? Read further as we explore the potentials of this slot.

About Book of Ultimate Infinity Slot 

The classic Egypt look has proven to be a winning combination for many slot game developers, which comes as no surprise to us. From the well-established Book of Dead slot to recent homages like the Book of Ra and Book of Kingdoms-there’s a suitable offer for everyone’s taste. This time, SG Digital decided to change the theme’s worn-out feel and added the innovative Infinity Reels mechanic. For those that don’t know, Infinity is a mechanic that consecutively expands the reel grid for every consecutive winning combination.
The Book of Ultimate Infinity starts the action on a 3-reel, 4-row grids. If you land 3 identical symbols or wilds on the reels, you’ll add a reel to your right and maximise your chances to win. The reels continue to expand as long as you add matching symbols to the right-most reel. Even though we’re talking about an infinite reel expansion, the system is capped at 50 reels. This isn’t precisely an infinite option, but it’s decent, considering that you win an x2 multiplier for each subsequent new reel.
To start the infinite round of this slot game, you have to place your bets first. The betting range begins at £0.20 and goes up to £50 per spin. Besides the dynamic base game, the Book of Ultimate Infinity slot offers an additional bonus game-the standard Free Spins Feature. Do not underestimate its potential, since we guarantee you that the developer tried really hard to stand out here. We’ll talk about the bonus games in short. The maximum potential win is capped at £250,000 which is a pretty big reason why you should try to take your gameplay to the infinity.

Design, Symbols and Graphics 

As the title suggests, this slot game belongs to the group of “Book of” slots inspired by Ancient Egypt. Even though we’ve announced it as a modern, innovative slot game, there are many familiar, already seen elements regarding the design. The reels are placed in a desert oasis surrounded by pyramids and palm trees. The colour palette features blue, gold, and green shades, accentuating the animations’ rich and clean feel. The soundtrack is also Egyptian with the right amount of Arabian feel to it and perfectly fits the atmosphere.
The paytable features the standard Royal symbols (A, K, Q, J), a dagger, an ankh cross, a Queen and a bird statue. The highest rewarding symbol is the burial mask of King Tut, which pays 0.25x your bet. The symbols’ payout potential is at the highest as soon as you start to land win upon win with the Infinity mechanic. There’s also a wild gold symbol with the name “WILD” that substitutes all standard ones, besides the scatter represented by the golden book.

RTP, Variance and Payouts for Book of Ultimate Infinity Slot 

The theoretical Return to Player (RTP) percentage of the Book of Ultimate Infinity slot is 96.5%, which is slightly above the average value. On the other hand, the game’s variance is high, meaning that it offers less frequent, but heftier wins. For players that enjoy playing on highly volatile slots, this would be an exciting game to explore. The maximum success is capped at 5,000x your bet, or if you prefer, £250,000. Overall, this is an excellent slot with a big potential to become hit among the players, thanks to the innovative mechanic.

Gameplay and Features on Book of Ultimate Infinity Slot 

The developer didn’t want to outshine the mechanic’s complexity with additional bonus features, and we’re glad about that. We’ve already mentioned the symbol multiplier triggered by the Infinity mechanic. Here, the first extra reel pays 2x the symbol value, and each additional reel increases the multiplier by 1. For example, if you have 5 reels on the grid, you’ll get a 3x multiplier. The only in-game bonus feature incorporated in the Book of Ultimate Infinity Slot is the Free Spins. So, let’s see how this game works.

Free Spins

The Free Spins feature is the main bonus sensation in this slot game. Triggering this bonus seems a bit unusual, as you have to wait for the golden book to show up on reels 6-15. If you’re lucky to add the necessary number of reels to reach the book scatter, you’ll enter the Free Spins round with 10 free spins. Moreover, you’ll get a notification in the base game on how close you are to reaching the golden book. There aren’t many slot games that evoke a sense of positive anticipation, which is great, and we were quite surprised when we saw this detail.
Before you start your free spins round, the golden book chooses one random special expanding symbol. This one will be active during your free spins round. If you manage to land an expanding symbol during this session, the grid will always add an additional reel to your right. When the selected symbol lands on 2 or more reels, it expands and pays once per symbol. If you’re lucky to reach the golden book again, you’ll get a retrigger and another round of 10 free spins. There are no limits on how many times you can retrigger this feature, or as we like to say- the possibilities are infinite.

Book of Ultimate Infinity Slot on Mobile 

SG Digital has optimised the Book of Ultimate Infinity slot to work on all mobile devices without issues. The design, bonus features and everything that is part of the game work seamlessly when playing on a smaller screen. This game is developed with HTML5, so it’s a mobile-friendly slot that adjusts to any small screen, whether it’s an Android, iOS or a Windows device.

Other Scientific Games Slots 

Scientific Games (SG Digital) is a famous slot game developer that offers various online slot games in terms of their design and mechanics. One of their releases is the Jinse Dao Tiger slot, the latest addition to their Jinse Dao series inspired by the Asian tradition. Another popular SG slot is their Secret Mission slot game, a spy-themed title with a high RTP and excellent payout potential. And if you want to take your game to the Wild Wild West, check out their game called Silver Stallion. You’ll be amazed by the crisp design and graphics and warm feel that this game offers. Moreover, it provides a potential payout of 2,500x your bet, so it sure brings out the best to light.  

SlotsWise Verdict 

SG Digital’s first game that features the Infinity Mechanic is excellent. They’ve done a great job combining the traditional book of design with the Infinity mechanic. Even though it doesn’t offer many bonus features, the Free Spins round feels just enough. The Infinity machinery itself offers excellent win opportunities. Overall, it’s a well-designed game with quality graphics that can be played on any desktop and mobile device. If this blend of Ancient Egyptian slot and Infinity mechanics sounds attractive, you should give this game a try.
