Our rating:
  • Another slot to use the infinity reels mechanic
  • Each win adds another reel with no limit
  • Build up multipliers for bigger wins

Book of Ultimate Infinity Infinity Reels slot comes from Red7 and I have to say, the name isn’t that catchy. That’s not what you really care about though so we’ll be focusing on the features and gameplay in this review. We should briefly mention the design though. It’s not the best in my opinion going for a classic Ancient Egyptian theme with mediocre graphics. You’ll see there are just 3 reels and 4 rows to start with, but don’t worth as these will increase. All you need to do is get a winning combination from left to right using the base symbols. These are as follows, ranked in ascending order based on their value:

  • Jack, Queen, King or Ace
  • Dagger or Ankh
  • Woman
  • Eagle
  • Sphynx

There is a wild symbol too, of course, which substitutes for all other symbols in a winning combination apart from the book and growing symbols. They appear on all reels apart from reel 1.

Book of Ultimate Infinity Infinity Reels Slot Bonuses and Features

Infinity Reels. If you haven’t played infinity reel before, it’s quite simple. If you get a win of at least 3 symbols, another reel is added to the right. If another identical symbol lands on this new reel, another reel is added and as you might have guessed from the name of the feature, this continues indefinitely, even if the book reel is reached. Furthermore, the first additional reel gives a 2x multiplier, and each additional reel increases the multiplier by 1x.

Book Symbol. This is the scatter symbol in the game and it can appear on a random reel between 6-15. If you reach this symbol, you’ll be given 10 free spins where it can also appear on reels 9-15. You’ll see your progress towards the book below the reels. A random symbol will also be chosen as the growing symbol which, if it lands on 2 or more reels, will expand to fill each reel. If you reach the book symbol in the bonus, another 10 free spins will be awarded.

Book of Ultimate Infinity Infinity Reels slot from Red7 is the latest game to use the infinity reels mechanic so I was intrigued to see how it did and whether it would offer any improvements. Unfortunately I think it suffers from the same flaws as before, namely that it can get quite tedious after a while and even when you get a long string of reels, payouts can be quite low because the symbol values just aren’t that high. You will eventually get the free spins bonus which is nice and with expanding symbols this works quite well, but I just think many players will get bored of playing this slot for too long. Perhaps you’ll like the infinity reels mechanics more than me, but I’d rather play a faster-paced game with bigger win potential. You can find other Red7 slots here too.
