Yggdrasil is back to rock (yes, we really made that joke) your world with the Gem Rocks slot. Hang on to the edge of your seat there buddy, because the Gem Rocks slot from Yggdrasil offers everything a player could wish for: some snazzy features, high volatility, and 4096 ways to win. It also has an RTP of 96.2% and a hit frequency of 20.8%. Besides all the tech stuff, it also has grade A quality animation and graphics. And with a maximum win of 460,850 coins to top it all off – Gem Rocks has it in the bag. That’s just the way Yggdrasil rolls (see what we did there, again). This provider doesn’t pop out a slot a minute like some other people (/cough/ Microgaming /cough/) and it shows. Gem Rocks is another well-polished product which offers both dynamic gameplay and innovative themes. It hits the spot for any type of player. So, buckle down and get ready to either play for free (check to the side) or keep on reading down below.



  • Gem Rocks is a cascading slot – meaning more opportunities for winning combinations and bigger wins overall.
  • Aside from being cascading, it also has 4096 ways to win. Again, this means more chances of landing wins than with a typical 20/25 payline slot.
  • The Gem Rock feature once triggered can seriously increase the value of big wins, especially if you get the 4×4 symbol.
  • Although it has an innovative game structure, Gem Rocks does not have many special features.
  • No Free Spins, Bonus Games or Wild symbols.
  • Given that the maximum bet possible is $50 it’s a little limiting for high rollers.
  • No progressive jackpots

Gem Rocks-slot-small The theme of Gem Rocks is based on a ‘rock made race of characters’, according to the software provider itself. It’s a bizarre idea, to be sure. But we think it has something to do with either ‘Golems’ from Jewish culture, which are typically made from mud and clay. But like pretty rock-like when they come to life. Or, for all you Marvel fans out there, you could say it looks the Thing from Fantastic Four. Either way – Gem Rocks is based on three different rock-made characters. They’re each powered up by a different gem. The gems are different in both color and value. But all this will become clear when we talk about gameplay, specifically the Gem Rock feature. Other than that, the graphics and design behind Gem Rocks is top notch as usual. From the exploding symbols, to the giant rock monsters – the animation is down to a T.


There are a lot of special aspects involved in the Gem Rocks gameplay. Not least of which is the fact that it is a cascading slot. Now, when a slot ‘cascades’, it means that symbols drop from the top of the reels down to the rest of the reels. Kind of like in a game of Tetris. When a winning combination hits, the symbols in the winning combo are destroyed (in Gem Rocks, they explode). New symbols then drop down to take their place. Because of this, spinning on a cascading slot is similar to playing on a slot with respins. With every win, you get an x amount of chances to win again – as long as winning combos keep hitting the reels. Now that’s a rocking deal. Besides this, Gem Rocks also comes with a Gem Rock feature and 4096 ways to win.

Gem Rocks Slot - Paytable

While Gem Rocks doesn’t offer the highest of payouts, it does deliver in frequency. The slot has a Return to Player rate of 96.2% and a hit frequency of 20.8%. Both of these numbers are decent for a game of this level. The special feature can be triggered often enough – although triggering the 4×4 Monster Rock is pretty difficult. After all, since it is a highly volatile slot game, it tends to pay out big but also not pay out small. Be prepared for this when betting on a slot game like this. The betting range between $0.10 – $50 is quite varied, especially given the coin values that you can bet per spin. The limit might be a little restricting for high rollers who want to go all out. The maximum win for Gem Rocks is 460,850 coins. An impressive sum, if we do say so ourselves. We’d be laughing all the way to the bank with that.
