How to Play

To start playing Gem Rocks, do the following:

  1. Open the game and click on the settings button
  2. Learn the rules of the slot, as well as the winning table
  3. Place a bet between €0.10 and €50
  4. Spin the reels of the slot machine

The game has 4,096 ways to win, as well as 8 main payment symbols. In addition, there are also special characters that appear on the screen only when certain conditions are met. They trigger the bonus features, increasing the win.

The slot also has giant symbols ranging in size from 2x2 to 4x4. Prizes received when several combinations appear at the same time are added up and paid out immediately. After that, the symbols from these combinations disappear, and others take their place according to the cascade principle. In general, cascades can last up to a maximum payout of €460,850.

Gem Rocks RTP and Volatility

The RTP of the slot is 96.2% while the volatility is low.

RTP is an indicator thanks to which you can find out the theoretical percentage of return of bets to players at the end of the game. It is worth remembering that this number is related to statistics and is difficult to apply to real game conditions when the user spins the reels for half an hour or a little more. For RTP to work, you need to play for much longer, for example, about a month continuously.

If the game has low volatility, payouts in it will occur relatively often. At the same time, the multipliers to the bet in such slots are much lower than usual. 


Gem Rocks

It may seem to you that the theme dedicated to stones and stone sculptures offers not too much fun entertainment. However, the provider managed to breathe life into the seemingly lifeless landscape, which is a gloomy-looking mountain. The fact is that stone golems with burning eyes live in this place, which can appear on the screen at any time and bring big wins.

The soundtrack of the game is another masterpiece from Yggdrasil. The music that plays during the game simply enchants anyone who hears it. We recommend turning off all other in-game sounds immediately so that you can enjoy the soundtrack without interruption.

The symbols of the title are tiles with the image of multi-coloured stones. They have different shapes, from a circle to a rectangle. The most profitable of them is a star-shaped stone, which brings up to €200 in profit.
