Great Gems Slot Review

Sharpen up your pickaxes and bring your shovels, because we are taking you mining. Great Gems is a five-reel, four-row video slot that benefits from 1,024 ways to win. Playable from £0.25 per spin, the 2019 release is brought to us by Red Tiger Gaming and Cayetano Gaming. Gamers will be taken deep into the caves, where they will be digging for enormous Gemstones. Use the help of the Extender feature and land Gems as big as 5×4. Also, benefit from the Senior Reels feature, which will remove up to 7 of the least paying gems for bigger wins.

Game Symbols

Once you enter the cave, you will hear nothing except the sound of drops of water falling, but once you start spinning the reels, you will enjoy an engaging soundtrack. The reels are packed with precious Gemstones and it will be up to you to collect as many of them as you can. The Diamond is the Wild that substitutes for all other symbols on the reels and also is the symbol that pays the most. Expect to see plenty of other Gemstones, like Rubies, Amethysts, Emeralds, and plenty of others of a different colour.

Now, the rules of the game are as easy as breathing, because you need to concentrate on breathing when you are so deep into the cave. The Red Tiger Gaming title features five reels, three rows and offers 1,024 ways to win. Land at least three matching symbols on adjacent reels, beginning from the far left reel, in order to win a payout. Betting is fixed at 25 coins, but the coin denomination can be altered, meaning that you can bet as low as £0.25 and as high as £25 per single spin. Once you get tired of hitting the Spin button, activate Autoplay and let the machine do all the work.

Special Features

Unfortunately, there are no free spins on the offer in the 2019 release. Gamers can benefit from two additional features. First, we will talk about the Extender feature, active during each spin. The Extender feature picks one of the symbols on each spin and it can extend it. The chosen symbol can cover only one cell, or it can get as big as 5×4, covering the entire reel grid and rewarding players with awesome wins. Also, there is the Senior Reels feature, which is triggered randomly. The Senior Reels feature will exclude up to 7 least paying symbols in one spin, to allow you to add high-paying symbols and secure you bigger wins.

When it comes to maximum payouts, punters can expect wins up to 8,100 times the bet in a single spin. The Diamond Wild is the symbol that pays the most, offering 8 coins for five of a kind. Use the Extender to make symbols larger for bigger wins. The Ruby is the highest-paying regular symbol, offering 4 coins for the maximum combination. Great Gems’ RTP is 94.63%.

Great Gems on Mobile

The Red Tiger Gaming title boasts simple, but crisp visuals and the reels run as smoothly as possible thanks to the amazing quality of the game. This is why the Great Gems video slot offers the same gaming experience on any device and it can be played on desktops and on handheld gadgets.


+ Crisp visuals

+ The Extender feature can get you 5×4 symbols

+ Playable across all devices


– No free spins

– No multipliers

– Could use more action


There are more than enough gem-themed video slots out there and we do not believe that the Great Gems video slot will find its place under the sun. The Red Tiger Gaming title offers little action, only two additional features, one of them is active on each spin, and the other is triggered randomly. The Extender can enlarge symbols up to 5×4, but it will not happen that often, while the Senior Reels feature is not as rewarding as you might think. All in all, there are plenty of other video slots with a similar theme out there and we advise you to look for precious gemstones elsewhere.
