About Gems Bonanza Slot

Pragmatic Play is one of the most prominent names in the industry even though it hasn’t been in the industry for decades. It releases high-quality casino games with a focus on slots and theGems Bonanza slot is one of them.

The Cluster Pays grid is made of 8 reels and 8 rows, which make 64 positions available for the winning combinations. Winning in the game requires matching symbols to form clusters of five. Wins count when the symbols are adjacent to one another in either direction. 

The grid of 64 fields is permissive to multiple winning outcomes forming across its entirety, independent of the area on the screen or symbol kind.

Tumble features, different modifiers, wild, Gold Fever Progressive and more features are available to be triggered in this game. The prizes can reach up to 10,000x the stake.

Design, Symbols and Graphics

The graphic design could have arrived in a more watered-down version and the game would have been just fine. However, Pragmatic Play has created extra details, such as the dynamic background and the cool premise that involves a Mayan calendar wheel and a foundry dripping with melted iron. 

Gems Bonanza Slot

Gems Bonanza slothas a lot of moving parts on the grid also. The gems are drawn and rendered very well and there are sparkles that emerge from the cutting of the gems as they disappear from the grid when they are a part of a winning outcome.

Another detail when you play Gems Bonanza is the sound. There is a mighty musical theme that keeps players company during the reel adventure and it's best to let it resound during it.

From small to big, the symbols can pay between 0.10x and 1x for five of a kind, 0.20x to 2.5x for seven of a kind, 3.75x to 50x for clusters of 15 to 19 symbols and so on. They are all gems in different colours.

Then there is the red orb that can create a colossal symbol in the location where it lands. These symbols can strike up a pose of 3x3, 4x4 or 5x5. The green orb is a lucky wild modifier that can add between 5 and 15 wild symbols.
