Enter a dark cave and follow the exploits of a mole who, in a deep space mining vessel, makes a great crystal miner. Genesis Gaming created an exciting slot machine game called Crystal Crater online slot for the web. It has an adventurous theme that encourages players to continue spinning.

This medium volatility slot machine has five reels and 50 paylines. The slot features high-paying symbols, low-paying card suit symbols, random wilds, free spins, and scatters, and in this slot review, we will go over all of it. The stacked diamond wilds not only provide the highest payouts, but they can also increase their overall value. Free spins can be won by landing scatter symbols, and there’s also a random wilds symbol that appears anytime. This feature is intriguing because it allows for better combinations by randomly dropping the stacked wilds onto the grid.

The number of available paylines in this slot is also exceptional. The slot features 50, a significantly bigger gamble than other real-money online slot machines. Add a high return-to-player percentage and innovative features like auto and turbo spin, and you’ll have a well-rounded product. This medium volatility slot is sure to keep you engaged. Our Crystal Crater review highlights questions you might ask about this fascinating slot.

Themes in Crystal Crater

Due to its underground location, this slot doesn’t lend itself to overt displays of artistic flair. Radi8 did an excellent job of injecting a personality into the shadowy underworld. Several rough rock formations can be seen in the distance while a stray stalactite dangles from the cave’s ceiling.

The grid’s theme is the showpiece: a magnificently personified mole looms at the top, his hands poised over a magical destruction button. This is not merely a cosmetic button; pressing it activates the bonus game. This slot comes to life because of his animated character, eccentric attire (a helmet and goggles), deep space mining vessel, and clever voiceover.

Generally speaking, the rest of the grid is straightforward. Jewels are represented accurately but lack visual impact. The music is a strong point, which you don’t see much in new online slots; the bouncy grouping of delicate keys gives the slot an upbeat, joyful atmosphere. Moreover, it has a slight echo evocative of deep beneath the earth.

Crystal Crater Symbols

Regular symbols

As any online slots guide will tell you, the symbols in these games can easily be separated into three categories. The most valuable symbols are those that depict a variety of precious jewels. Jewels such as ruby, citrine, amethyst, and emerald fall within this category. The various card suits each have a minimum payout potential. The card suits include spades, diamonds, clubs, and hearts. 

Wild Symbols

This incredible slot machine has not one but two random wild symbols. The first wild symbol, depicted as a blue sign, stands for any missing fundamental icons. Suddenly, it could fall out of the sky. The other has visuals reminiscent of crystals and is stacked on the reels. These stacked diamond wilds will open the game to more combinations and bonus features.

Bonus Symbols

Free spins can be won by landing scatter icon combinations, and stacked wilds symbols appear at random. A large diamond icon reads “bonus,” representing the bonus symbol. This feature is intriguing because it allows for better combinations by dropping random wilds onto the grid.

Paytable and Winning Combinations

The betting range on this slot is fairly tiny, going from a minimum of 0.01 to a maximum of 0.80. If you spin the reel and get five stacked diamond wilds on a single line, you win 500 times your bet. Crystal Crater could be called one of the top penny slots on the market right now.

Crystal Crater Payout Symbols

For the complete payout for five matching symbols, let’s delve even deeper into the list:

  • Diamond wild = 500x
  • Amber = 200x
  • Ruby = 150x
  • Amethyst = 100x
  • Emerald = 100x
  • Club = 75x
  • Heart = 75x
  • Diamond = 50x
  • Spade = 50x
  • Bonus symbol = 50x

Free Spins and Bonus Rounds in Crystal Crater

Stacked Diamond Wilds

The stacked diamond wilds symbol is the highest-paying icon in this online video slot. It can also fill an entire reel when it does so. It’s always exciting when this happens since it guarantees higher compensation in the Crystal Crater game. The stacked wilds’ random gameplay is something to watch out for.

Random Wilds

It’s impossible to predict when the random wilds symbol will come, but it’s a big deal when they do. More random wilds are scattered around the reels when the bonus symbols explode, increasing the odds of a big payout.

Free Spins

Triggering free spins with a mystery choice requires hitting three bonus icons. Gamers must balance the number of free spins they desire and the number of random wilds they want on each spin. The fact that you can retrigger the free games with a different collection of bonus symbols helps ease the pressure of making a mystery choice. It sets this game apart in any real-money online casino app library.
