Cosmic Jewels Slot Review
Unless you’ve been living under a rock your whole life, you’re bound to have heard that diamonds are a girl’s best friend. Our Cosmic Jewels slot review makes this love for sparkling gems clear, as you’re about to slip into a spacesuit and embark on an adventure into space with a jewel-hunting female astronaut.
Determined to search every inch of the cosmos, this beautiful blonde has roped you into helping her find valuables jewels. Stars shine brightly in the background as you walk in space, but it’s diamonds, opals, amethysts, and emeralds you’ll be hoping to see floating across the five transparent reels.
While the blonde fluttering her eyelashes will be all the encouragement many of you budding astronauts will need to blast off into space, the Cosmic Jewels slot machine boasts plenty of exciting features that make this exploration an irresistible proposition.
Boasting 1,024 ways to win, wild symbols, a Scatter Bucks feature that can deliver payouts of to 4,000 credits, and free games, this space-themed slot promises a truly unforgettable experience.
Explore the Wonders of the Cosmos
If you can’t already tell from the user interface, the Cosmic Jewels online slot has been developed by High 5 Games. This is the same experienced team behind popular titles like Cirque Chinois and Red Cliffs.
It’s certainly not the most visually appealing game we’ve ever seen, but our expert reviewers approve of how the symbols hover in a frameless 5x4 game matrix. The transparent reels allow you to watch the stars twinkle during each spin, with a thin blue line separating each of the five reels. The most disappointing aspect of the design is that the background is static, so the stars don’t move an inch.
Our review of Cosmic Jewels slot revealed that a total of 10 different symbols feature on the reels. This includes Ace, King, Queen, Jack, and 5 symbols. An emerald is the least valuable of the three different jewels that sparkle on the reels. Bigger rewards are on offer for finding amethysts and exquisite orange opals. We’ll tell you more about the two special symbols later in our Cosmic Jewels online slot review.
A calming soundscape accompanies the reels spinning. It captures the relaxed ambience of space, but you’ll be hoping to hear the funky tune that loudly rings out from your speakers to signal wins instead.
Our Cosmic Jewels review team was also pleased to discover that this space-themed slot is playable on both desktop and mobile devices. We spun the reels on tablets like the iPad and Samsung Galaxy Tab, as well as Android and iOS smartphones, with the same slick experience provided across all platforms.
Slip Into a Spacesuit From 0.80 Credits
The fact that Cosmic Jewels is a five-reel, four-row online slot means it offers a dreamy 1,024 ways to win.
The only downside to High 5 Games slots that utilize such a structure is that they usually require a sizable minimum bet. Unfortunately for the low rollers among you, the Cosmic Jewels slots game doesn’t break the mold when it comes to this matter. You’ll have to stump up at least 0.80 credits per spin to slip into a spacesuit, while a max bet of 400 credits is available for the thrill-seekers among you.
Our Cosmic Jewels review team was over the moon to find a return-to-player (RTP) of 96.5%. Such a generous payout percentage combined with the fact that this is a medium variance game should help to ensure your space adventure lasts all night long.
Seeking Wins That Are Out of This World?
Then look out for the beautiful astronaut on the second, third, and fourth reels when you play Cosmic Jewels slot online. She represents the powerful wild symbol, which substitutes for all symbols. While your attention will be drawn to the large diamonds she holds in each hand whenever she floats onto the reels, it’s the credit value that flashes in the black meter that you’ll be most interested in checking out.
This meter displays how many credits you’ve been awarded, thanks to the inclusion of High 5 Games’ popular Scatter Bucks feature. You could win up to 25x your stake for each wild symbol that appears.
Another reason to embark on this outer space adventure is for the chance to unlock free games. Three planet symbols awards 7 free games, while 15 free games are awarded whenever you land four. You’ll also see five planets dropping into view once in a blue moon, which equates to 30 free games.
Our expert reviewers would have enjoyed free games more with multipliers and the chance to retrigger the feature, but it’s still a good enough reason to immerse yourself in the Cosmic Jewels slot machine.
Check out our list below for other fantastic free-to-play High 5 Games slots.
Spacewalk Alongside Other Beautiful Ladies
Cosmic Jewels is one of many online slot machines that introduces gamblers to a beautiful astronaut.
If you’d like to blast off into outer space with other beauties, you should check out Astro Babes by Playtech. This 5-reel, 100-payline slot is set in a fictional space world, where five lovely ladies can appear to create wild reels and deliver extraordinary wins of up to 5,000x your stake during free spins.
For some Megaways action, match galactic symbols in the Starquest slot machine. This six-reel Big Time Gaming slot boasts up to 117,649 ways to win. It’s extremely volatile, but the female astronaut can appear as a stacked wild symbol across four reels to deliver some truly mind-boggling wins.
3.. 2.. 1.. Blast Off!
It might not be the most attractive game High 5 Games has ever released, but the Cosmic Jewels slots game boasts a whopping 1,024 ways to win and some very exciting bonus features.
It’s always fun watching the beautiful astronaut spacewalk onto the reels to deliver random credit wins, and you certainly won’t be complaining if you get lucky enough to unlock the maximum of 30 free games. And with an RTP of 96.5%, you can’t have any excuses about embarking on this space adventure.
So, what are you waiting for? It’s time to slip into a spacesuit and play Cosmic Jewels for free on this page before spinning the dazzling reels at one of our recommended online casinos.
