Mining is a little unusual but often used theme when it comes to online video slots and Gem Rocks — a game produced by Yggdrasil Gaming — adds to the extensive cache of titles that flaunt the said theme.

Gem Rocks is a six-reel slot that boasts of four rows and an eye-popping 4,096 ways to win which means that the standard payline structure is not utilized but wins would be formed as long as there are matching symbols on adjacent reels starting from the left-hand side. Solid rock frames those reels and there’s a meter on the left-hand side, which would be discussed later on in this article.

But before you can join this rocky race, you must first set your bets. By clicking on "Coin Value +/-" you can set coins size which ranges from the uncommonly 0.002 to 1. "Max Bet" is used to set the maximum bet allowed, and "Spin" sets the reels in motion. "Autoplay" option is used to turn the reels automatically without interruption for a chosen number of times.

Cascading rocks are typically very dangerous, but in a game like Gem Rocks, punters would be more than happy to see them blowing up and new ones dropping into their places. The oversized symbols during normal gameplay, and the massive Monster Rocks won’t necessarily complete winning lines of matching icons, but they definitely help in making it easier to do so.

Having 4,096 different ways to win across the six reels could seem a little too much at the beginning, but once the combinations begin to land, it all becomes al lot clearer, although working out multipliers when you see a number of identical symbols on a reel could take some getting used to.

Gem Rocks is a one attractive online slot game that has smooth gameplay and a feature that a lot of punters would like in the Dropdown Wins, in this case with a small improvement of Monster Rocks. Set the Autoplay and sit back and watch all the action! It comes with an RTP of 96.20%.


All the symbols are blocks of stone of various colors and holding a range of shapes – a star, a crescent, a circle, a blue triangle, a grey triangle, a square, a diamond and an orange cross. There are no wilds or bonus symbols in Gem Rocks.


Dropdown Wins

The bonus feature is all about the gameplay in Gem Rocks and it’s named Dropdown Wins, which is Yggdrasil’s version of “collapsing reels” from other game developers. Basically, any symbols involved in a win would explode and disappear only to be replaced by more falling in from above. New wins can then be formed and this process keeps on going until there are no more winning matches.

During the Dropdown Wins the meter on the left becomes active because, after a particular number of consecutive wins, larger symbols (Monster Rocks) fall onto the reels:

  • Two Wins = a 2×2 Monster Rock
  • Five Wins = a 3×3 Monster Rock
  • Nine Wins = a 4×4 Monster Rock

When there are no more wins, the round is over and the meter resets.
