Introduction to Gem Rocks
Gem Rocks may seem like a simple game with a basic theme; in reality, this is far from true. This is because the game has a few interesting and original features that can’t be found in many other slots. These include the 4,096 Ways to Win feature, which is very cool; after all, many slots boast that there are 243 different ways to win, but this feature has over ten times the number of winning opportunities, which is seriously impressive. How is this even possible? It is mostly due to the fact that the game has six reels instead of the standard five, with each reel having four positions.
It is also possible to win all ways with this game, which is a generous extra feature many players will enjoy!
There are lots of reasons to check out Gem Rocks - you just need to make sure that you are feeling lucky first!
Gem Rocks review / first impressions
Our first impression of Gem Rocks is that the game is a lot of fun. The graphics look good but they do have a cartoon style to them that makes the game seem quite childish. This is far from the case; in fact, this game is very fast-paced and there are a few big wins that make the gameplay very exciting.
Having over 4,000 ways to win might seem like a bit much to start with; in reality, the gameplay is fairly simple and easy to understand. We suggest that players spin the reels a few times for free first, as this means you will understand how the game works before you spend any of your hard-earned cash.

Payout ratio (or RTP) of Gem Rocks slot
Gem Rocks has a payout ratio, which is also known as the return to player or RTP, of 96.2 per cent.
Gem Rocks slot graphics
This game may have a theme that is somewhat reminiscent of Bejewelled, but this doesn’t mean that the graphics are retro or old-fashioned; in fact, the graphics for this game are very modern and detailed, which is unexpected!
While you wait for the game to load, you will see the game logo. This is made out of purple rocks and a few of the gems. During the actual game, they mostly just look like normal gems; however, during the loading screen, they have been personalised with faces, arms and legs.
Once the game has loaded, you will see the reels set in the side of a rocky mountain. The mountain is crumbly, so it looks like the reels are being held up with dark purple rocks. In the background, you can see a purplish sky. We really like this subtle colour theme that kind of looks like a cartoon, which makes the game feel fun and fresh.
The game has both high paying and low paying symbols. The low paying symbols are represented by playing cards, with these symbols appearing on the reels frequently. The high paying symbols for the game are represented by gems, which look pretty valuable. You will see diamonds, sapphires and emeralds as the reels turn.
The game also has a fun, upbeat soundtrack. This definitely makes the game more fun; in fact, we think that some players will end up bobbing their heads along to the catchy little tune!
Gem Rocks game theme
This game has a simple gem theme. This theme is very popular in online slots, especially when slots were first created. This is partially because gems are valuable, so they fit in well with slot games, and they are easy to draw and illustrate, which was probably useful in the past!
There are lots of gem-themed games out there, but we think that Gem Rocks stands out from the rest. This is partially due to the modern graphics but is also linked to the fun, medium-high volatility action that can be found throughout the game.
How to play Gem Rocks slots
This game is played on a 6x4 grid, which is quite unique for a slot game - but don’t worry, it is still fairly easy to spin the reels. The only thing you need to do before you start playing for money is set your bet, which you can do using the control panel. Simply click the + or the - button to adjust your bet accordingly.
Once you are happy with your bet, you can start to play. You can do this yourself or you can use the autoplay feature to spin the reels for you.
Gem Rocks game volatility
Gem Rocks is a medium to high volatility game. This means that it has some big cash prizes, but the wins are not as frequent as the wins in a low or medium volatility game. You could spin the reels for quite a while without forming a win, which is risky; however, the wins are bigger, so you just have to decide if the risk is worth taking.
We think that medium to high volatility games are best suited to players who have money to spend, as you will ideally want to play for a while so that you will have time to trigger most of the bonus features and special symbols.
How to win at Gem Rocks slots
You will win a cash prize if you manage to get at least three matching symbols in a row but will win more for longer combinations, such as four matching symbols, five matching symbols or six matching symbols. You should also be aware that different symbols have different values; for example, the red star is the most valuable gem in the game and can pay out between 20 and 200 coins for a win.
You should also keep an eye out for the game’s bonus features.
Gem Rocks bonus features
The Free Spins bonus round
Gem Rocks has a fun Free Spins bonus round that will be automatically triggered if you manage to land the HOT symbol anywhere on the reels. When this happens, the free spins gamble wheel will appear on the screen and you will get to choose between eight free spins or a gamble. If you decide to gamble the free spins, you could potentially win even more free spins - but you could also lose all your free spins, so you should definitely weigh up your options before making a decision!
It is also worth noting that the free spins round can come with a multiplier, which makes it even easier for you to boost your winnings.
