About Great Gems Slot

Great Gems is an exciting online slot game developed by Cayetano Gaming. Played on five reels and four rows, you’ll have 1024 ways to win on every spin. Featuring a fun gem themed design, every symbol on the reels is a different type of jewel, with values ranging from 0.2 up to 8, dependent on how many symbols are involved in the winning combination. The highest paying symbol on the reels is the Wild, which not only offers the highest payout for a five-of-a-kind combination, but substitutes for all other pay symbols too.

There’s two epic special features on offer, in the form of the Extender which can increase a symbol’s size to cover up to 5x4 reel positions, whilst the Senior Reels feature eliminates low paying symbols for bigger potential prizes.
