Casino game developer Yggdrasil sure has come miles in the last few years when it comes to the quality of their slot machines. The group's first games were bland and bled together in terms of presentation and features and just blatantly sucked. Things have taken a turn for the better recently though, as the quality of the games has gone way up, rivaling what you'd find from big boys like Microgaming, NetEnt, or Playtech. The perfect example of this modernization is the Gem Rocks slot, which takes you deep underground where you try to combine gemstones to win big.
Gem Rocks is a 6 reel, 4096 ways to win video slot that's set far underground and sees you working with these big rock monster to get the gemstones to group together for wins. The game has a very cool cascading wins system, which sees you having winning gems crushed and removed, only to be replaced by new gems above. This lets you have the chance to string together a series of wins. The game has a multiplier of sorts, which builds up as you string together wins. You can get a 2x2, 3x3, or 4x4 sized rock creature to come down, splitting into one of the gems and stringing together another big win.
The feature set in Gem Rocks is simplistic in the way that I explained it, but it does pay out. The game has a posted return to player (RTP) percentage of 96.2%, which is about average for a Yggdrasil slot but generally high for an online game.
I have put some good time with Gem Rocks, and I have to say that this is among my favorite Yggdrasil slots. This game is a bunch of fun, and you can rest assured that you're going to have a real winner here.
If you're looking for a game that plays good on your mobile devices, then Gem Rocks is also a good choice. I dropped this into my Samsung Galaxy Note 8 and found no issues playing it when compared to how it performed on my desktop.
So get your mining hat on and let's head down to the depths of the world and crush some gems and win some big cash! Who knows, you may end up making a hardened friend that helps you out.
