Features Crystal Towers by Big Time Gaming is a casino slot built around cluster pays and a shifting 3D Tower. The base game starts with 80 symbols across 5 rows, and wins form from groups of 5 or more matching symbols connected horizontally, vertically, or across the Tower’s sides. When wins land, symbols collapse and new ones fall into place, creating chain reactions.
The slot uses Wilds and Multiplier Wilds to support winning combinations. A Trigger Wild appearing in a winning cluster unlocks 10 Free Spins. In the bonus round, the Tower expands from 6 rows to 10 rows, increasing the symbol count from 96 to 160, while up to 10 Wilds can be added during the feature. The game is described with high volatility and an RTP range of 86.41% to 96.37%.
A Bonus Buy option gives instant access to the Free Spins feature for 60 times the stake. Players can use the demo version to play for free and practice before playing for real money.
