Review of Gem Rocks

The Flinstones mixed in with the ice age is how we can pretty much sum up this exciting Yggdrasil slot game. Who didn’t absolutely love watching The Flinstones when they were younger?! Now you can feel as though you are in that stone age time hanging out with Fred and Wilma. Maybe Yggdrasil had this old-school movie in mind when making Gem Rocks as the main theme of the game is rocks and gems with a unique grid and appearance.

There is a lot of colour and big features to look forward to in this slot game, some of the in-game mechanics definitely remind us of previous slots they have created such as Big Blox as they also contain block breaking features. This type of in-game feature can also be compared to cluster pays, but it feels much more exciting when it has the appearance of huge blocks being broken along with a cash win!

How to play Gem Rocks slot

Gem Rocks’ layout is rather different than other yggdrasil slots, or your regular slot game because it actually consists of 6 reels rather than 5. Not only are the reels different, but there are 4096 ways you can win in this game! Before you begin rockin’ in this online casino slot, you should be sure to adjust your betting limits. This can be done by using the coin value tabs at the bottom of the grid with the plus and minus symbols.

The minimum amount in which you can actually bet is £0.10, which is fantastic for those of us who prefer taking it slow in the beginning and do not wish to dive right in with the big bets from the start. The maximum betting amount you can place is £50, which is also a decent max bet. Once you have chosen and decided, you can enter the world of Gem Rocks and smash some of those beautiful gems.

Not only are the reels different, but there are 4096 ways you can win in this game!

The Gem Rock Feature

When you have had 2, 5, and 9 consecutive drop down wins, the Gem Rock feature will be activated and you could earn yourself a top casino bonus. You will be able to easily see your consecutive wins on the Gem Rock meter on the left side of your game grid which is also fun to watch light up and induces further excitement in this fantastic game.

What this does, is award you with a single Monster Rock which will land on the top of the reels and is made up of identical game symbols. The Gem Rock Meter has the ability to collect up to 9 consecutive wins, and no more Gem Rock features can be activated until the meter resets itself. The way in which the meter resets itself is when you have missed out on a win, making it non consecutive. There are 3 ways in which the Gem Rock Feature hands out rewards and it goes as follows:

  • 2 Consecutive wins - 2x2 Monster Rock
  • 5 Consecutive wins - 3x3 Monster Rock
  • 9 Consecutive wins - 4x4 Monster Rock


If you are one who really enjoys those slot games with a cluster pay feel, then Gem Rocks is the slot game for you, however if you are more for the classic style of slot game then it’s probably not up your street. There is nothing conventional about this slot by Yggdrasil and this is exactly why we love it so much.

From the music to the sound effects, it’s strange because it has a very calming atmosphere, but at the same time the thumping rocks create that anticipation and eagerness to trigger the Gem Rocks features! It’s extremely fun when slot providers think outside of the box and create slots other than the ones with the fruity symbols, and letters and numbers Gem Rocks will rock your world.
