Play Cosmic Crystals for Free

If there's one video slot machine theme that is sure to capture the imagination, then it is the theme of interstellar gems. Cosmic Crystals serves up a fairly impressive portion of cosmic soup, complete with some glistening chunks of crystal croutons. It's definitely a game that will appeal to a vast majority of slot players with its astronomical sense of wonder, not to mention the minimalism of the design which places stunning colors over a deep black background, conjuring images of far away galactic clouds.

The game is also designed to make mobile game play easy, allowing players to tap and swipe their way through the spinning action. The mobile slot machine has a simple menu system the option to set up a continuous auto-play for non-stop spins.

Deep space spinners will find that Cosmic Crystals is a very fruitful online slot machine. Thanks to the slot's low volatility game play, there is a high likelihood that a winning spin will be found with each and every stake that is placed. And if a win isn't formed on any of the 50 permanent pay lines, then the video slot's bonus re-spin will activate until a successful formation is formed. Sounds like a ridiculously good deal, doesn't it?

Well, not exactly. Because even though the game is guaranteed to turn every bet that is placed into a winning prize, the size of the potential prizes are somewhat minuscule in comparison to most slot machines online. For example, the game's lowest valued icons – 10, J, Q, K and A – will pay out some far-from-galactic line bet multipliers from 2x to 75x whenever three to five matching symbols align. Considering that player's have to place the maximum of 50 pay lines per spin, then you are only going to break even when you find five matching K or A icons to receive a 60x or 75x prize respectively.

There are some more lucrative symbol combinations to be found in this low volatility online slot, with five different crystal symbols that will pay a range of five-in-a-row prizes from 100x to 1,000x. Of course, these bigger wins are much less common, but they could help to boost the betting balance in the right direction after a series of low value prizes. Another thing that could also help punters boost their balances is the fact that many multiple pay lines can be triggered at once – there are 50 of them in play after all!

This game's minimum bet is 0.20 credits and the maximum is 50.00 credits, providing plenty of room for maneuver depending on whether you are a low or high roller.

There are no free spins on offer in this online slot machine, which is fair enough considering that the game features a free re-spin during the base game. The slot machine does provide a wild symbol, however, which is represented by a special golden gem symbol.

This valuable crystal appears sporadically over the reels, substituting for all other icons to potentially create a winning combination. Whenever the wild symbol does appear, it will expand vertically to cover all three reel positions, making it even more likely that more than one pay line will be triggered for a larger potential prize pay out. What's more, the any wild icon that appears on a non-winning spin will remain there throughout the free re-spin feature.

Cosmic Crystals by Iron Dog Studio is definitely an exciting prospect for spinners who like to see the wins come in on a frequent basis thanks to a special free re-spin element that ensures a win is found. That said, the online slot machine has one of the lowest pay out potentials in the market, with most of the wins paying out less than the size of the total bet. Thankfully, the game's 50 pay lines and expanding wild icon could ensure that some wins move your balance to astronomical heights.
