How the Game Plays

Crystal Towers is an innovative 3D-style slot by Big Time Gaming that moves away from traditional flat grids in favor of a rotating cube-shaped tower. Set against a cosmic backdrop of floating rocks and high-tech energy grids, the game features a four-sided tower where symbols drop into place from above. It uses a Cluster Pays mechanic, requiring five or more matching symbols to touch horizontally or vertically to secure a win. A unique aspect of this format is that clusters can wrap around the corners of the tower, connecting across multiple faces. Every winning combination triggers a reaction, where symbols are removed and replaced by new ones, allowing for continuous chains of wins.

Free Spins Explained

The main bonus is triggered when a Trigger Wild is part of any winning cluster, awarding 10 free spins. The round starts with an expanded tower of six rows. As the feature progresses, the tower grows taller on the 3rd, 5th, 7th, and 9th spins, eventually reaching a maximum height of 10 rows and holding 160 symbols. During this mode, the tower persists between spins; instead of a full reset, only the bottom one or two rows are removed at the start of a new round. Additionally, up to 10 random Wild symbols can be added to the tower at the start of each free spin.

Special Wilds Explained

The game features three distinct types of Wild symbols. Standard Wilds substitute for regular cube symbols to help form clusters. Multiplier Wilds carry specific values that boost the payout of any cluster they are a part of. Trigger Wilds are responsible for activating the free spins and can also retrigger the round, providing an additional 10 spins if they appear in a winning cluster during the bonus.
