Crystals and gems are often used as a focus topic in many online video slots by most leading manufacturers. Those shiny things are loved by all - come and play them, you'll surely like how they shine on the reels!
In the world of Online Slots, crystals can appear anywhere, so there are many slots that cover this crystal theme somewhat, this or that way. For example, you can find crystals in caverns or mines, while some other slots are just showing a reel screen full of various kinds of crystals, without any story behind that. Such slots are especially easy to play and thus are very good for beginners.
In crystal themed slots, the most valuable gems are likely to act as wilds as scatters: these could be diamonds or just the most shiny crystals of all you have in a slot. Bonuses more often than not include Free Spins, or, as it frequently happens with the crystal themed slots, free falls.
