Great Gems

Collect a fistful of precious gems on the slot from Cayetano Gaming to score wins of up to 8,100 times your stake. Great Gems is a fast-paced game with high volatility, Extender Gems that will expand up to 5×4 size and Senior Reels where low-value symbols are removed for more chances to hit mega wins.

Slot Details

Great Gems is a video slot with five reels, four rows and 1,024 ways to win. Pays are awarded for three to five adjacent symbols from left to right only. Your quest for the precious stones on desktop or mobile starts at 1.00 credit and peaks at 60 credits per spin. The game is highly volatile with an RTP of 94.85%, which is well below the industry average.

A sci-fi scene with kryptonite-like rocks on each side is the background to a frameless game window that is populated exclusively by gem stones. They appear in different shapes and sizes according to their pay value. At the low end are simple blue, green and yellow gems followed by red, orange and blue gems held by silver clips. Pays for a single five of a kind range from 1x to 2x your stake. At the high level are fully framed silver and gold gems in blue, green, orange, purple and red gems. Hit five across the line to win 2.2x to 8x your bet. A shiny diamond is the wild symbol substituting for all symbols and awarding a win of 4x your bet for a single 5OAK.

Great Gems Slot Features

The game has two modifier features that can pack quite a punch on any spin. First up is the Extender Gem, which is one framed icon that moves to a random reel position on every spin. It can extend randomly an any time to increase horizontally and vertically from a 1×1 symbol to a mega 5×4 size which would cover the entire screen.

The second feature is what the developer calls Senior Reels where one to seven of the low-value symbols are removed from the reels for the current spin. The Extender Gem feature can trigger on Senior Reels which significantly increases the chances to hit a win with a premium symbol.

Final Verdict

Admittedly, I wasn’t too keen on reviewing this slot as it looks rather bare and had initially little that appeared interesting enough for a full review. However, that changed after playing it for some in demo mode. It is highly volatile and the two features are quite powerful and will lead mostly to mega wins when they hit in the right spot. A win potential of 8,100 times your bet is surely enticing enough to give it a few spins.
