 Cosmic Crystals is one of the more simple, but truly beautifully designed online slots by Iron Dog Studios. If you prefer plenty of colour and a tranquil, calming theme which includes elements of casino traditionalism then you should definitely give this slot a try. Covering 5 reels and 3 rows, this game is complete with a combined theme of space and crystals, producing a fairly unique theme which you are unlikely to find anywhere else due to the originality of the design. That being said, this game is not too far from more classical slots due to the inclusion of card symbols, fruit symbols and other traditional style design features.

This game offers an easy to play design, which includes a very generous number of paylines. The 5 reels covers a busy betway pattern of 50 ways to win, which includes all directions and allows for plenty of betways. Having 50 paylines to work with on a 5 reel slot is brilliant, making this slot very appealing to every player. The generous number of betways is needed, as the RTP rating of this game could be better. The RTP of this game is 95.01% which is actually below average, making this game more challenging than your usual online slot. The RTP rate balances out the generous betway pattern which makes this slot an overall medium, fairly volatile slot which offers good winning chance.

Cosmic Crystals has a betting range of £0.50 to £100 per spin, which gives you some room to use when choosing your own stake. A wide betting range is the key to making slots as flexible and accessible as possible, as they accommodate for all player styles and intentions. This game does feature an above average minimum stake, making it a more expensive slot to play  - this combined with the higher maximum bet limit offered in this game makes this slot more suited to those looking to place higher stakes at this online slots casino. This game includes fairly flexible betting range which does allow for players to use a range of betting styles, ensuring no one is left out in enjoying this very visually appealing online slot. 

Payouts and Symbols 

 Cosmic Crystals is a simple design based on gemstones and set in space - a combined theme which creates a very original and unique design. If you love glowing visuals and a colourful reel, then you will appreciate how Iron Dog Studios has designed this slot to appear. The slot consists of 5 reels and 3 rows, offering a smaller and straightforward online slot which is easy to manage and never complicated.  The visual of this slot is completed by the beautiful symbols, which include various glowing gemstones in a range of colours set against a dark reel background to offer a stunning display. The jackpot payout up for grabs in this colourful slot is 1,000x your stake - this can produce up to £100,000 which is sure to put a smile on any player’s face at this online slots casino.

There are a whole range of coloured gemstones in this slot including pink, blue, green, yellow and purple. The highest value gemstone symbol of this collection is the yellow gemstone, which gives you 20 times your stake for a payline - this can offer a maximum win of up to £2,000 which is pretty strong for a basic symbol payout in a main game. This slot does lack in multipliers or any bonuses which increase the payouts, meaning the highest payout available is the jackpot of 1,000x your stake - which still requires a full reel of wild symbols which can be fairly hard to find, but still achievable with the 50 betways available in this exciting slot. 

Bonus Rounds 

 Cosmic Crystals has one bonus feature, which centres all of the focus of this simplified online slot. The bonus feature used in this game is the Respin Bonus Round, a popular bonus feature which combines wild symbols with respins to offer players an increased chance of winning the jackpot - which in this case is up to 1,000x your stake or £100,000 as a maximum win. To access this important bonus feature, all you need to do is make a winning payline - not only will you win the payout from the payline, you will automatically trigger the Respin Bonus Feature of this game. This feature is simple and will lock any wild symbols into position, if there are any on your reels, before giving you a free respin to jumble your symbols in the hope of creating a winning payout of up to 1,000x your stake. The bonus feature of this game may be simple and basic, but it can really help you out in reaching that jackpot payout which is otherwise hard to activate through the main game of this slot.
