The good people of Yggdrasil are taking us back to the Stone Age with Gem Rocks, a six-reel, four-row video slot that offers 4,096 ways to win. Visually impressive, the 2018 release is literarily carved in stone and the three central features are the Monster Rocks, which come in different sizes to secure big wins.

First, you will have to start the Dropdown Wins and get at least two consecutive respins to summon the Monster Rocks. This visually impressive game and its gem-hearted stone monsters will help gamers land wins as big as 9,000 times the bet in a single spin.

The symbols used in the Yggdrasil title are written on stone plates. The Red Star is leading the pack, being the symbol that pays the most. The Moon comes second and is followed by the Emerald and the Diamond. The Triangle, Square, another Diamond and the X sign represent low-value symbols.

There are also three different Monster Rocks, which are made out of identical symbols, and we could consider them as kinds of Wilds, since they will choose one of regular symbols and turn into that particular symbol.

The reel grid of the 2018 release is carved in stone. The Gem Rocks video slot features six reels, four rows and offers 4,096 ways to win. All you have to do in order to win a payout is land at least three matching symbols on adjacent reels, starting from the leftmost reel. Symbols appear in regular size and in 2×2 formation.

One spin requires a fixed bet of 50 coins, but the coin value can be altered, meaning that you can bet as low as $0.10 and as high as $50 per single spin. The Dropdown feature is constantly active, but we will talk more about it in the following section.


There are no standard free spins on the offer in Gem Rocks, but there could be plenty of consecutive winning combinations, thanks to Dropdown Wins. Every time gamers land a winning combination, the winning symbol will disappear, making room for new symbols to appear and hopefully form a new winning combination.

Dropdown Wins are closely connected with the Gem Rock feature. Form two, five or nine consecutive dropdown wins and you will land 2×2, 3×3 or 4×4 Monster Rocks. Keep the progress of consecutive dropdown wins by watching the gem rock meter on the left side of the screen. Gem Rocks are constructed of identical symbols and they will help you land bigger wins. The trick is to land nine or more consecutive wins to get the biggest, 4×4 Monster Rock.


As we already mentioned, the symbol that pays the most in the Yggdrasil title is the Star, offering 200 coins for five of a kind. The maximum possible payout gamers can expect is set at 9,000 times the bet for five of a kind. Try to land as many Monster Rocks as you can in order to secure bigger wins. Gem Rocks’ RTP is 96.20%.

When talking about visuals, the Gem Rocks video slot is simply impressive, because it boasts state-of-the-art graphics and a fitting soundtrack. The reels run as smoothly as possible in the 2018 release. As for the special features incorporated, not everybody will like the fact that the Yggdrasil title does not offer standard free spins, but the Dropdown Wins and the Gem Rock feature represent interesting additions.

The gem-hearted Monster Rocks are there to help you land big wins, so don’t be scared of them, because the bigger the Monster Rock, the bigger the winning opportunity.
