I have to be honest and say that Big Time Gaming did a tremendous job with the visuals. This 3D reactor format and amazing geometry make you feel as if you are building the tower yourself. BTG placed the pokie machine on top of a mountain that also seems like a portal into another dimension.
You will find yourself high in the clouds with nothing but the clear sky above you. If you are scared of heights, then I suggest that you do not look down. Nevertheless, it is always fun to walk on the clouds, eh?
With each new spin, you get 5 rows of multi-coloured blocks on the top of the mountain. After a non-winning spin, all of them are dropped down the portal and are carried to another dimension. Apart from having 7 different blocks that act as regular symbols, you also have 3 types of Wilds.
The regular Wild is there to substitute for all regular symbols. The Wild Multiplier will boost your win when part of a winning combination. Also, there is the Triggering Wild or the Scatter Wild. When this Wild is a part of the winning combination, you get 10 free spins.
Even though the Crystal Towers pokie machine might seem complicated, you will learn to play the game in a matter of spins. Thanks to the 3D design, you have four 5×4 grids. After every spin, you basically go around the entire tower to see whether you have any winning clusters on the tower walls.
To win a payout, you need a cluster of at least 5 horizontally or vertically connected matching blocks. Each win triggers cascading reels. This will help you form multiple wins in a single spin. You bet as low as $0.10 and as high as $5 per spin. The BTG title is of high variance and offers a 90,050x max payout. Crystal Towers RTP is 96.37%.

With every winning spin, you trigger cascading reels and get multiple wins in a single spin. Winning blocks are destroyed and new blocks appear. Wilds appear on almost every spin, thus helping you form winning clusters more easily.
Also, Wilds are important for triggering free spins. Well, 1 specific type of Wild, called Triggering Wild. You just need a Triggering Wild as a part of the winning cluster to get your 10 free spins. Also, you can use the Buy Bonus option if you don’t want to wait for the Triggering Wild.
The main innovation in the Crystal Towers pokie machine is the 3D Cluster Pays feature. So, you don’t form clusters only on 1 grid, but actually on 4 grids. Basically, on every side of the tower. It is fun to see how blocks get destroyed when they are a part of the winning cluster.
When you introduce Wilds and cascading reels, you get a fun slot machine that will keep you busy for quite a while. My biggest base game win was around 65x. I had this amazing run of cascades and plenty of Wild Multipliers included.
When the Triggering Wild gets you 10 free spins, you will start the true adventure. You start with a 6-block-high tower and, along the way, you get more blocks until your tower is 10 blocks high. At this point, you will play with 160 blocks.
Also, after the second free spin, you get up to 10 Random Wilds on every free spin. If the Wild is not part of a winning cluster, it turns into a Sticky Wild and remains on the grid until it gets to the bottom of the tower. It is also important to mention that, after every spin, 1-2 bottom rows are destroyed.
You can retrigger the feature with the little help of another Triggering Wild. My best round included 20 free spins, plenty of Wilds and Wild Multipliers. I won a total of 86x. For me, it was quite easy to trigger the feature. Within 400 spins, I triggered free spins 6 times, which is quite nice. Of course, wins were not that big every time.
If you don’t want to wait for the Triggering Wild, you can always buy free spins for 60x the bet. The price is not that big but there is the danger that you will not get your money back. This was often the case with me.
Face it, when it comes to innovation, Big Time Gaming is one of the best in the business.
The 3D reactor format is a breath of fresh air in the pokie machine world where all slots start to look alike. I firmly believe that this type of slot will be extremely popular in the future.
I was lucky enough to win often and that most of my wins are quite decent. Maybe that’s why I enjoyed testing Crystal Towers pokie that much.
My favourite part of the 2025 release is the Free Spins feature. I rate Crystal Towers 8.7.

Seems a bit complicatedCould use more extrasPredrag is a huge fan of pokie machines, especially the ones packed with extras. He considers his job a fun way to spend his days and sometimes feels guilty for getting paid just for having fun. Pokies have become his passion and he is always prepared to explore and review new titles.
With almost a decade of experience in reviewing video slots, Predrag has always tried to provide users with honest reviews based on facts. His favourite pokie developer is Big Time Gaming, and his number one pokie machine is White Rabbit.
Also, he never says no to a good epic fantasy story. That’s why he also loves Play’n GO and its Rise of Olympus. When he wants to party, he always goes for NetEnt’s Guns N’ Roses. Betsoft’s The Slotfather pokie is a perfect choice when he is looking for a good crime story.
