How to play Book of Ultimate Infinity mobile slot

What happens when you mix expanding scatter pays with infinity reels? You get this Book of Ultimate Infinity slot.

What are Expanding Scatter Pays? That’s when (in the free spins usually) one symbol is chosen to pay like a scatter and expands over the reel. So you get more wins over more paylines. Think Book of Dead slot or the Book of Ra Deluxe 6 review.

What are Infinity Reel slots? That’s when you start with 3 reels, and on every win, reels are added to the right, to infinity. Instead of paylines the symbols themselves have a specific value and the more symbol you get on consecutive reels, the bigger your wins. Think the Gods of Gold Infinireels slot.

If all this is making your brain hurt, don’t worry. We’ve got you covered: this is a simpler game than you might think.

This Book of Ultimate Infinity slot takes the best of both worlds

What Red7 are trying to do is take two popular slot features and mash them together in a fairly basic looking Egyptian slot theme.

We thought it was just a gimmick too until we started playing. And the clever thing here is that it’s not all that they are doing.

For one, every time a new reel is added the multiplier increases. So at first, you might think the paytable is a little poor (you need 4 of the highest-paid symbols just to get my bet back?!) when you add the multiplier it makes it all worthwhile.

Because a fourth reel gives you a 2x multiplier on all wins, a 5th reel a 3x multiplier and so on and so forth, until you hit the bonus reel in this Book of Ultimate Infinity slot game.

What’s the bonus reel?

On each spin, one reel is picked to be the bonus reel – usually somewhere between reel 6 and 15. If you get to that reel you’ll trigger 10 free spins.

And then boy do those Expanding Scatter symbols come out to play. Because, don’t forget, you don’t get pay symbols on paylines, you get them on the number of symbols on the reel.

These reels are 4 rows high, so two rows of expanding symbols anywhere on these expanding reels will give 8 of a kind wins. If you get that expanding scatter pay on all reels, and 8 or 15 reels full of symbols and wilds, you might see yourself getting something close to that 5,000x your bet max win.

Will this Book of Ultimate Infinity slot payout as much as Tiki Inifinity Reels Megaways? Probably not. It’s still around the same kind of wins as the Book of Atem WowPot slot.

But it’s more than a little different, and it will have you on the edge of your seat as those multipliers bring you visions of Pharaoh’s gold straight to your living room. Fun on any day of the week.

In-game bonus features

Pays: When 5 or more identical symbols appear across consecutive reels, each symbol will pay out a singular win value. So each pharoah symbol will pay out 0.25x your bet, each sword pays out 0.10x your bet, and each J symbol pays out 0.05x your bet.

Wilds: The wild symbols substitutes for all symbols except the Book symbol or the expanding growing symbols. Wild can appear on all reels except reel 1.

Infinity Reels: On any spin, if a minimum of 3 identical symbols lands in reels 1, 2 and 3, and extra reel is added to the right. If it gets an identical symbol in the extra reel, another extra reel will be added. This continues until no more identical symbols are seen.

The first additional reel awards 2x the symbol win amount. Each successive reel reached increases the win multiplier by 1x. So 4 reels have a 2x multiplier, 5 reels a 3x multiplier, 6 reels a 4x multiplier and so on on.

Book Symbol and Free Spins: The Book symbol is a scatter symbol. At the start of each spin, one random reel is selected (from 6 to 15) to contain the book symbol. If enough reels are added to reach the reels up to the book symbol (see infinity reels above), you'll catch 10 free spins.

During the free spins, one symbol will be chosen to act as an expanding scatter. So the Infinity reels will work as they do, and then when you find no more of the winning symbols, that's when the expanding scatter comes into play.

The symbol will expand, cover the reel, and pay like a scatter, and does not need to be on consecutive reels.


Review closing thoughts

We didn't think it would work, but this Book of Ultimate Infinity slot on mobile surprised us at every turn.

From the multipliers adding a little extra zest of excitement in the base game, to the expanding scatter pays working remarkably well in the free spins, this is a strange but fun way to pass the time.

If you are not a fan of the Infinity Reels slots this won't convince you otherwise. But if you are looking for a wonderful mashup of two great features, then you'll enjoy a brilliant little real money casino game that deserves this 4-star mobile slot game review.
