The difference between Crystal Classics and the most mediocre Greek Legends is surprising. It's hard to believe that these 2 titles were created by the same provider, and the difference between them is only a few weeks! Crystal Classics is Booming's first Cluster Pays slot and we hope to see a lot of fun here.

Slot details & Wager limit

This game has 3 high-paying symbols and 4 fruit symbols which are low-paying ones. You need to match 5 to 25+ matching symbols, horizontally and/or vertically, to win. All wins trigger the cascading reel mechanic, instantly removing winning symbols from the 7 reels, 7-row grid. Existing symbols fall down to fill in the gaps, and new symbols fall from the top to completely fill the playing field again. This process repeats as long as you keep winning, creating repeat wins during each spin. Each win also activates the Random Wild or Wild Multiplier feature.

Crystal Classics RTP and Volatility

8 
The slot has 95.27% RTP and high volatility.
The only real drawbacks of the slot are its somewhat boring name and 95.27% RTP, which is below the market average with high volatility. However, this is not a big deal since the main game offers a lot of thrilling rides with its cascading reels feature.

Crystal Classics Theme

9.1 
The playing field, decorated with a golden frame, is set against a simple background that changes color depending on what exactly is happening on the reels. The theme of the slot is fruity, so it's no surprise that oranges, lemons, cherries can be seen on the grid, as well as many of the familiar symbols of Lucky 7 and Golden Bells. There is a simple navigation menu at the bottom and a large game logo at the top. The slot's fruity design is clearly designed to evoke nostalgic feelings in players, and the old-school soundtrack sounds good here like never before.
Crystal Classics Theme
Major symbols are Lucky 7 that pays up to 100x, Star that pays up to 65x, Golden Bell that pays up to 40x. Low-pitched symbols are fruits: Apple pays up to 25x, Orange pays up to 25x, Lemon pays up to 10x, and Cherry pays up to 10x. The wild symbol replaces all standard symbols and can be assigned a multiplier of 2x, 3x, or 5x.

Mobile compatibility

Mobile compatibility
This is a modern slot machine created using HTML5 technology. This means that it is not only compatible with PCs, but also with all mobile phones and tablets. You can enjoy the fruit theme combined with modern bonus features and unusual mechanics anywhere, anytime, just remember to be connected to the internet!

Bonus Rounds & Free Spins

The bonus round is triggered when at least 4 Scatters appear on the playing field in the same cascading wins sequence. The slot will reward you with 10, 15, 20, or 25 free spins, for 4, 5, 6, or 7 Scatter in the same sequence, respectively. If you get 3 or more Scatters during this feature, you will get 5 or more extra free spins. The bonus round is played in the same way as the base game, but you are guaranteed at least 1 Wild or Wild Multiplier for every single win! Moreover, the range of multipliers has been expanded and now the maximum multiplier is 100x!

Crystal Classics - BF

Crystal Classics Max Win

8.9 
The maximum win is 27,556 times.
Here you can win 27,556 times your stake. This potential is made possible by the free spins bonus round, in which Wild Multipliers can be increased up to 100x! This feature may not be launched as often as we would like (about 1 out of 402.6 spins), but the basic game itself is quite pleasant.

Overall Rating

9.2
We are pleasantly surprised! This is a potential breakthrough material for a provider. We've seen the concept of random Wild Multipliers before, but Booming has made it original. Nice to see how the white laser beam generates up to 3 Wilds per cluster win. With a few Wild Multipliers, you can get solid payouts also in the base game, and with a multiplier of up to 100x in the bonus round, almost anything can happen!
