Crystal Cascade

In the Crystal Cascade slot, OnlyPlay takes you into a colorful space world where various types of gems can fall on an 8x8 grid. It also features multicolored wild gems that substitute for other symbols to help complete clusters. The game uses the cluster mechanics, where you win by connecting five or more matching symbols horizontally or vertically. Winning clusters explode and new symbols cascade down to create more winning opportunities. As you spin the reels, you fill up a progress bar around the TNT Booster. When this bar is filled, you have a free TNT Booster at your fingertips. You can decide when to use the booster. Once you activate the bonus, it clears all symbols from the reels. Another progress bar can fill up and trigger the free spins round. During this round, you can get a color booster that explodes all symbols of the same type on the reels, boosting your winning chances. Each colour booster also offers you five or more free spins.
