Crystal Classics

Crystal Classics Overview

Crystal Classics, designed by Booming Games, is one of those classic brick and mortar slot machines that has been revolutionised and brought into the 21st century. Crystal Classics has plenty to offer the modern gamer with gleaming graphics, a giant board, and an exciting selection of features. The highlight here, however, is the top payout which ranges up to 27,556x your stake. This exciting maximum prize is achieved with the help of multipliers, which come in sizes up to 100x the stake. The only slight letdown for Crystal Classics is the RTP, which at 95.27% is a little on the disappointing side.

Looking at the bonus content, this game has, first and foremost, a useful cascading reels feature. Meaning that when you score a win, the winning symbols are blasted off the reels and replaced by a new set, giving you more chances to score wins from the same spin. There are also two different wild features included in this game. The first is a random deposit of three wilds at any time in the base game. The other is that some wilds can be upgraded into multiplier wilds to help boost wins. There is also a free spins game, which has a more lucrative set of multiplier wilds. All features will be explained in more detail later on in the review.

Theme and Symbols

The theme for this game is a classic fruity theme but with modern features and graphics. This slot is much like a collection of games that seem to be emerging in the market, which incorporate an element of nostalgia into a modern digital slot game. They do this by using classic slot symbols, a classic soundtrack and a background that reminds players of a simpler age. All of these elements combined have the sepia-tone effect of transporting players back to when you could only play slots in casinos and bars and when jackpots came out in floods of coins and hard cash. For some, this was the golden game of slot gambling, and developers want players to associate their new products with this epoch.

The background for Crystal Classics is just a simple diamond graphic design in red. The shape of the design has probably been chosen to emulate the shape of the crystals that are part of the most attractive symbols in this game. Apart from that, Booming Games have elected for simple in this design, letting the action on the playing board provide most of the visual entertainment value for this slot.

The board is a sizeable gold-fringed square with a darkened interior. This shadow effect makes the symbols on the various reels pop nicely from the screen.

Speaking of the symbols, these comprise the various fruity icons that one will see on the reels. These include the Cherries and Lemons, both of which are low-value symbols, followed by the Oranges and Apples. The most valuable symbols, however, are the golden Bells, the Stars and the lucky 7s. The Bells, Stars and 7s are all majors. The Bells payout at 80x the bet for 25 symbols or more, whereas the stars payout at 130x. The most valuable symbol, however, is the lucky 7 worth 200x the stake. The specials in this game are the Crystal wild and the golden Crown scatter, which activates the free spins game.

Features

The first feature in this game is the cascading reels feature, triggered every time a win is registered. When activated, the winning symbols disappear from the reels to be immediately replaced by a new set. This mechanic gives you multiple chances to create wins from the same spin. The mechanic only stops when a new set of symbols does not trigger a win. In which case, you start using your spins again, and the wins accumulated from the feature are paid out.

There are also two wild features in this game. The first is that three wilds can be randomly deposited on the reels at any time in the base game, helping to score more wins. The second is that wilds can be upgraded to multiplier wilds. These multiplier wilds boost the payout of any win they are part of by the value attached to them. In the base game, these values range up to 5x.
The final feature is the free spins feature, activated when players land four or more scatters on the reels simultaneously, giving you five free spins. In the free spins mode, however, there is a guaranteed cluster that disappears. The wild multiplier values also increase in the bonus game, ranging from 2x to 100x your stake.

Conclusion

Depending on how you feel about cluster pays, this could be a real winner for players looking for nostalgic gameplay with all the modern amenities that digital free casino slots allow. That low RTP rate does continue to plague gameplay, however.
