    Are you ready for a space adventure?!

    Well–known developer Iron Dog Studio is taking players deep into uncharted parts of the Universe on a mission to collect as many interstellar gems as they can.

    Space themed slots are not a novelty and there is quite more than a few of them in the gaming world, such as Astro Legends as one of the latest additions. So let’s check out how UK developer approached this subject.

    In the background, …

    … vast Universe with purple nebula, planets and countless stars shining brightly. The soundtrack is composed of electronic soft beats and a drum roll with every winning combo. The futuristic vibe it gives away contributes to the atmosphere in a great way.

    Visually, this title has a beautiful and colorful design. Graphics are top - notch and animations, although subtle, are extremely effective.

    Betting Options and Symbols

    The hunt for interstellar gems is happening on 5 x 3 grid with 50 fixed paylines.

    As always, players can adjust the bet and in this case, it is in the range from 0.50 up to 100 $ per spin.

    When it comes to symbols, …

    … on the reels, you’ll find standard 10, J, Q, K, and A as low – value icons. The most you’ll be able to get from this group is 75 coins for landing 5 As on the payline.

    For some more generous payouts, you’ll have to line up some of the crystals. There is 5 of them – pink, purple, blue, green and yellow. The last two are the highest paying among them. The green gen will award you with 500 coins for landing 5 while the yellow one will get you 1.000 coins.

    Special Features

    This release doesn’t have any additional games but it doesn’t mean it lacks in appealing features.

    Another symbols appearing on the reels is the Orange Gem or Wild and just as any Wild, it will replace any of the symbols. But a very important thing about this Gem is that every time it appears, it will expand over the whole reel and create more wins for the players in one single spin. 

    Besides the expanding Wild, …

    … you’ll also encounter Re – spin round. This feature is activated every time a non–winning spin occurs and it won’t stop until the first winning combo takes place. During this round, the Wild reels stick until the end.


    All in all, Iron Dog Studio created a visually appealing slot with two bonus features.

    Expanding Wild and Re – spins triggered with every non–winning spin are certainly great additions to the game. The betting range will accommodate both those players on the budget and the high rollers. The developer also made sure that release is available on all sorts of platforms.

    The only downside is that the game becomes pretty repetitive after some time. But if you like hitting the Autoplay and relax while the reels spin, this won’t bother you at all.
