About Great Gems Slot

Prepare to go spelunking for the cavern’s hidden treasures in this Cayetano Gaming slot. Cayetano have produced some fantastic casino slots in recent years and have come at us with another to add to the collection. Great Gems will have you digging for jewels in no time! The high paying symbols in this slot come in the form of gilded gems such as Diamond Wilds, Rubies, Amethysts, Topaz and Emeralds. The lower paying symbols feature on the reels as smaller different coloured gems. Keep an eye out for the Great Gem that can appear on every reel; this will expand to fill up to 5x4 reel spaces for potential big wins. After an extension seven gems can be excluded for an improved chance at a win!

How to Play Great Gems Slot


The stake per spin can be set via the total stake in the bottom left of the game window. The “+” and “-” buttons will allow you to alter the total stake; the minimum bet to go jewel hunting is 25p per spin.


When you are ready to play the Great Gems slot the spin button will send the reels into motion. This is found at the bottom right of the game window and will send the reels into motion with every spin potentially activating the Extender Feature.


The auto button can be found directly next to the spin button and will allow you to set between five and 100 autospins. Here you will also be able to set session loss limits and stop on wins over limits.


If you need any extra information about the Great Gems slot the Pays button will tell you everything you need to know. This button can be found via the menu at the top right of the screen and will explain symbols, bonus features and pay lines.

Great Gems Slot Features


The Great Gem will appear somewhere at random on the reels during every spin. When this happens you will hear a sound effect and the gem will be clearly marked with how far it is going to extend. The gem can expand to be up to 5x4 on the reels which increases the big win potential massively!

Senior Reels

After an extension during every spin the Senior Reels Feature has a chance to activate. When this happens up to seven of the lowest paying symbols can be removed for an improved chance for a win. Lower paying symbols being excluded means that high paying symbols can be left for potential big wins.

Slot Boss Says
