Big Time Gaming‘s release, Crystal Towers, incorporates a three-dimensional reactor format, distinguishing it from more conventional slot machine designs. The gameplay is structured around a central tower, initially composed of five rows and featuring a total of 80 symbols. The visual presentation emphasises geometric clarity and dynamic motion, contributing to the immersive quality of the gaming experience.
Engaging gameplay
Winning outcomes are realised through the formation of clusters consisting of five or more identical symbols. These clusters may connect either horizontally or vertically, and the game mechanics permit connections that wrap around the sides of the tower, thus expanding the potential for various cluster configurations. Upon the activation of a winning cluster, the symbols involved collapse and are replaced by new symbols cascading from above. This mechanism introduces the possibility of sequential wins within a single spin, as subsequent clusters may form with the newly introduced symbols.
The slot further integrates several types of wild symbols, each serving distinct functions. Standard wilds may substitute for other symbols to facilitate the completion of clusters. Multiplier wilds augment the value of winning combinations by applying a multiplier to the payout, thereby increasing the potential returns. Trigger wilds, when included in a winning cluster, are instrumental in initiating the Free Spins feature, granting the player ten complimentary spins.
Free spins
The free spins phase alters the structural composition of the tower. Initially, the grid expands to six rows, increasing the total number of symbols in play to 96. With each subsequent spin during the free spins round, the tower grows taller, ultimately achieving ten rows and accommodating 160 symbols. This expansion not only amplifies the total number of symbols present but also enhances the diversity of possible cluster formations and, consequently, the win potential.
A notable feature within the free spins mode involves the dynamic resetting of the bottom rows after the second free spin. This mechanic ensures that either the first or the first two rows are refreshed, maintaining variability in symbol distribution and sustaining engagement across the free spins sequence. Additionally, up to ten wild symbols may be randomly introduced to the grid on each spin during this phase, further increasing the likelihood of forming high-value clusters and achieving substantial payouts.
Nik Robinson, CEO at Big Time Gaming, said:
Crystal Towers doesn’t just push boundaries—it transcends them.
The striking 3D visuals combined with our signature cluster mechanics create a slot that is endlessly exciting, immersive, and unforgettable.”
With Wilds, multipliers, and a tower that grows as you play, this is one of the most innovative releases of the year—and one of the most fun to play.”
