Crystal Towers

Crystal Towers is a groundbreaking 3D-style slot by Big Time Gaming, blending visual innovation with popular cluster mechanics. Set atop a sky-bound mountain portal, the game features a rotating cube-shaped tower made from crystal-like blocks. It breaks the mould of traditional slots by offering gameplay on multiple sides of the tower, while the cascade mechanic keeps the action going during the same round. 

Symbols on the Crystal Towers slot range from colourful gemstones to patterned premium cubes and Wild icons. Each spin drops a new tower into view as symbols fall into place. Moreover, the game is accompanied by a soft ambient soundtrack that complements the animated spectacle. 

The Crystal Towers slot has a return to player (RTP) percentage of 94.30% with medium-high volatility. It is suitable for all experience levels and supports a wide range of stakes. 

Spin the 3D Tower 

When you first launch the Crystal Towers slot game from our online casino, you may be surprised by the slot’s setup. Rather than a 2D grid, this game features a 3D cube made up of four sides, each with five reels and five rows. 

Despite its irregular design, you can play Crystal Towers online just as you would any other slot game. Start by setting your stake by clicking the arrows beneath the bet box. When you’re ready, click the spin button to play a new round. 

Crystal Towers uses Cluster Pays to award prizes. A valid cluster is formed whenever five or more matching symbols land next to each other, in any direction. Clusters can form across all four sides of the tower and are automatically detected. 

Only the highest payout per cluster is paid, and all prizes are multiplied by the stake. 

Seven standard cubes deliver the slot’s regular payouts. The purple cube is the most valuable, awarding between 0.5x and 5x the base stake, while the red cube’s payouts range between 0.3x and 5x. 

Crystal Towers Features 

The Crystal Towers slot game offers engaging mechanics with a fresh perspective, making this one of the most popular online slots by BTG. 

Reactions 

Every winning combination in Crystal Towers activates a reaction. During a reaction, winning symbols pay out before disappearing from the cube. Symbols above them fall into their place while new symbols land from above to fill any gaps. 

If a reaction creates a new winning combination, the feature is retriggered. This continues until no new winning combinations are formed. 

Wild Symbols 

Crystal Towers has three distinct wild symbols. While all three substitute regular symbols to help complete or develop winning combinations, Multiplier and Trigger Wilds have additional abilities. 

Multiplier Wilds boost regular payouts they are part of by their respective multiplier, while Trigger Wilds activate 10 free spins whenever they form part of a winning cluster. If two or more Trigger Wilds activate the bonus, each contributes 10 free spins to the balance. 

Crystal Towers Free Spins 

The Crystal Towers free spins bonus is just as entertaining as our latest casino promotions, and is played on a special, six-row 3D tower made up of 96 symbols. 

During the third, fifth, seventh, and ninth spins, an additional row is added. As a result, by the end of the bonus, the tower spans 10 rows and is made up of 160 symbols. 

As of the second free spin, up to 10 wild symbols are added randomly across the tower. Moreover, only the bottom one or two rows are removed. 

Any Trigger Wilds that form part of winning combinations add a further 10 free spins. The Crystal Towers bonus continues until free spins run out or the maximum win limit is reached.
