About Crystal Classics Slot

Crystal Classics slot is brought to us by Booming Games, who seemed to make a very good job out of a classic fruit slot. It merged perfectly the modern mechanisms with a fruity theme. As the winning combinations are formed in Cluster Pays, this slot has no fixed paylines.

In the base game, there could be a multiplier of up to 5x and in the bonus round this number can go up to 100x. In Crystal Classics you can win a maximum of up to 27,556x the stake, as a maximum win potential. Played on a grid set of seven reels and seven rows, this game can offer a lot.

Design, Symbols and Graphics

This classic slot has a nice background all in red nuances. The fruit symbols dominate the reels, which made this game also a fruit slot. The graphics are plain and clear and the overall design is very elegant. The golden border of the reels also matches some of the symbols, while it gives a perfect outline of the grid.

As for the animations, on a new spin, old symbols fall off the grid so new ones can replace them. Also when we have winning combinations, they are all touched by a laser-like beam of the Crystal Classics slot logo wild. The soundtrack is rousing and a bit retro.

The green apple, the orange, the cherry and the lemon are the low paying symbols. Upper on the paytable, are the star, the bell, and the lucky seven. There are two special symbols, a wild and a scatter. You need between five and 25+ matching symbols in a cluster to win. A wild symbol is rewarded each time there is a Cascade and it replaces regular pay symbols. The scatter is used for triggering a feature.

RTP, Variance and Payouts for Crystal Classics Slot

The Crystal Classics RTP is a little bit lower than the industry average, capped at 95.27%. The volatility is high meaning, winnings can be less frequent, but larger at times if they occur. To better understand these terms, you can read our variance, volatility and RTP guide.

You can place bets between £0.20 and £10 on a single spin.

Gameplay and Features on Crystal Classics Slot

The first feature that is obvious in the base game is the Cascading Reels feature. Then is the Multiplier Wild and a Free Spins feature. Also, there is a Bonus Buy option that is not available for UK players.

Cascading Reels Feature

You need from five to 25+ matching symbols horizontally or vertically to form winning clusters. The Cascading Reel feature removes the symbols off the grids and puts new ones in their place. Each win can trigger random wilds or multiplier wilds.

Multiplier Wild Feature

When the positions behind a cluster are empty, the logo wild symbol fires a laser-like beam on the positions and generates 1 to 3 wilds, in that space. It might do that for a second time as well, increasing the random multiplier of x2, x3 or x5. The wild will disappear with the winning combination, and usually a new wild or a multiplier wild is generated for the new win. More multipliers generated are added together.

Free Spins Feature

By landing four scatters in the same cascading sequence, trigger the Free Spins round. You can get 10, 15, 20 or 25 if you land 4, 5, 6 or 7 scatters respectively. Three or more scatters during the feature award you +5 extra spins. Here you can have at least 1 wild or multiplier wild per distinct winning cluster. The winning multiplier range is expanded for certain values up to x100.
