Gem rocks

Although the moon landing in 1969 was a real milestone in the history of man, imagine if they were able to be up there a little longer than they were and were able to explore the area a little more thoroughly than they were able to back then. Indeed, that is what Yggdrasil ponders with their own slot game plot description for Gem Rocks slot game.

The Swedish developers, who have been making head waves in the gaming industry despite their relative infancy compared to other major developers, have decided to provide players with a unique experience by creating a ‘Tetris’ style vibe of a game with a number of rocks being akin to little monsters and gem-hearted giants.

The developers have really gone to town with this particular title and have provided players with a host of exciting and brilliant elements and this Gem Rocks slot review will explore all of them and provide players with an explanation as to what they can expect when spinning the reels on this game.


The first incredible thing that is noticeable in this ‘Tetris’ style game is that there are six reels instead of the traditional five that are found on the vast majority of slot games, whilst the number of winnable combinations available is simply eye-watering. Yggdrasil have included a whopping 4,096 ways to win, however advanced players of the Swedish developer’s previous games will know this is the norm for the company.

There are no betting lines to speak of, therefore players can only change the coin value and multiply it by 50 to get the total bet per spin. The coin range is 0.01 to 1.00, and the total bet is 0.50¢ to $50.00.

“Max Bet” is used to set the maximum allowable bet, and “Spin” is used to set the dial in motion. The “AutoPlay” option is used to rotate the reels automatically without interrupting the selected number of times.

Any three of the same kind on the reels will be worth a prize that increases when you land 4, 5 or 6 of the same kind on additional reels, but if any of these reels has more than one example of a winning symbol, the prize is multiplied. For example, if one of the reels has 2 of the same symbols, it is doubled and those multipliers can be multiplied by itself, leading to potentially huge rewards. While most symbols occupy a single slot on the reel, it’s quite common for giant symbols to land in 2×2, 3×3, or even 4×4 blocks, making it easier to score high-value wins.

Symbol values vary, from the brown cross or purple diamonds through to the green, white, blue and aquamarine gems which are each worth a little more. A crescent moon gem is the next best rewarding symbol in the game, but by far the best prizes come from the red star.

Feature Bonuses

When looking for Gem Rocks bonus features, there are no free spins to speak of, however the Cascading Reels feature can more than make up for its absence from this game.

The feature is triggered when a winning combination is made as it will then disappear and make room for more possible combinations to be made. Building up as many of these combinations will help to build the bar within the win-meter to the side of the game, which will then see a Monster Rock creature appear when it reaches the top.

The Monster Rock will appear as the same color as a standard symbol and comes in the form of a 2×2 block, which should help to provide more winning combinations. The Rock Monster can continue to expand with more winning combinations, with a huge 4×4 Monster being formed after a ninth win in a row. Players will certainly reap the rewards if they can manage to get him to replicate the color of some of the top symbols in the game.

RTP (return to player)

Yggdrasil’s Gem Rocks slot game has a return to player rate (RTP) of 96.2%, which should provide players with some confidence that they are within a chance of winning the maximum prize on offer. Gem Stone slots maximum jackpot pays over 9000x your stake, therefore handing out $921.00 using a 0.01 spin and a huge $460,850 with the maximum bet set at 50.00 coins.
