Big Time Gaming is reaching for the stars — quite literally — with its latest release, Crystal Towers. Released on May 28, 2025, it features a cosmic backdrop built around a fully immersive 3D tower. This innovative cluster pays slot aims to redefine how players interact with reels, symbols, and bonus mechanics.
Innovative Design
Unlike anything seen in traditional grid or reel-based formats, Crystal Towers introduces a rotating tower of symbols. Wins occur across multiple sides simultaneously, thanks to a dynamic Cluster Pays mechanic. Players begin their journey on a 5-row Tower with 80 radiant symbols. Wins are created through horizontal or vertical clusters of five or more symbols. But the real spectacle begins during the Free Spins. The Tower can expand up to 10 rows and 160 symbols, unlocking colossal win potential.
The visual impact is immediate — sleek 3D animations and a comic book sci-fi style create a distinctive look that’s more arcade adventure than classic slot. “Crystal Towers doesn’t just push boundaries — it transcends them,” said Nik Robinson, CEO at Big Time Gaming, adding that the slot’s mechanics and design “create a slot that is endlessly exciting, immersive, and unforgettable.”
A Trio of Wilds
Key features include a suite of Wilds designed to amplify wins. Standard Wilds substitute for other symbols to complete clusters, while Multiplier Wilds boost any win, they’re part of— and Trigger Wilds go one step further, unlocking 10 Free Spins when they’re part of a winning combination.
Once inside the Free Spins round, the format changes again. Players start with a 6-row Tower, which gradually increases to 10 rows. After the second Free Spin, only the bottom one or two rows reset per spin, and up to ten Wilds are added to random positions. This drastically improves the chances of back-to-back cluster wins and cascading symbol chains.
Crystal Towers Bonus Buy-In
For those who prefer to skip the base game buildup, Crystal Towers includes a Bonus Buy feature (where available). Players can jump straight into the Free Spins round for 60x the bet — a high-octane shortcut into the heart of the action.
With a creative twist on cluster mechanics, ambitious visuals, and escalating gameplay that evolves as you spin, Crystal Towers is one of Big Time Gaming’s boldest releases to date. And for players ready to twist, match, and rise above the ordinary, this latest launch delivers a dazzling new perspective on slot design.
Crystal Towers is now available at new casino sites in the UK.
