Gems are attractive and generally valuable stones which make ideal gifts for your better half if you feel the need to apologise for something; they are also a familiar theme for online slot machines and maybe you’ll be able to buy one of you hit that big win. Crystal Clear is all about gems – it’s developed by Realistic Games and you can read all about it below.

Crystal Clear is a five reel slot with three rows and ten fixed paylines; those reels are transparent and if you peer into the darkness behind you can just make out a tropical scene with calm seas and palm trees dotting the shore.

There are six gems of different colours as the main symbols and these are red, blue, purple, green, orange and yellow.

The wild symbol is a clear diamond and as well as substituting for all other gems to make winning combos, it’s integral to the bonus feature and described in more detail below.

There are no bonus or scatter icons in Crystal Clear.

Bonus Features

Crystal Clear Bonus Spins

At the beginning of each spin there’s a stack of eight wilds on each reel and that number is also denoted below each reel. Every time you spin a win, all non-wild symbols on that combo change into wilds and you receive one free respin. The numbers below the reels now reflect the new number of wilds on each reel.

With each successive win the process continues until you win the jackpot (10000x your line stake for five wilds) or there are no more wins.

Verdict

Crystal Clear is a compelling slot with some good looks and a clever bonus feature we’ve not seen before – it makes you want to keep playing and there are certainly some big wins to be won for the luckier players. It comes with an RTP of 95.45%.
