Crystal Gems is played on 5 reels and 20 pay lines. When I played this game I managed to activate the free spins very fast and I was really surprised about that. A mine cart full of gems is the scatter symbol in this game. As soon as I started playing I got 3 scatters and I got 8 free spins. The most important thing here is that the wild symbol is even more valuable during the free spins because it offers a multiplier of x 2, x 3 and x 4. I won something around 50 x bet. But this was a really good start. It is possible to retrigger the free spins in the Crystal Gems video slot game. It is also possible to get more free spins at the beginning if you activate the feature with more than 3 scatter symbols. So if you get 4 scatters then you will get 10 free spins and for 5 scatters you will get 12 free spins. During my session I managed to activate the free spins couple of times but the wins were somewhere around 10 x bet and 30 x bet.
There is another random feature called Mystery Crystal Pick where you need to pick one gem which hides a cash prize. During my session I did not activate this feature at all. This came as a surprise because usually it is easier to activate the random feature than the special feature. Anyhow, I had a really good session when I played the Crystal Gems video slot game. For that reason I will recommend this game to anyone.
